4 EIGHTY-FIRST ANNUAL REPORT OF THE COMMISSIONERS OF THE MADISON METROPOLITAN SEWERAGE DISTRICT FOR THE CALENDAR YEAR 2010 INTRODUCTION The Eighty-First Annual Report of the Madison Metropolitan Sewerage District is dedicated to Jon W. Schellpfeffer, Chief Engineer and Director. After 36 years with the District, 9 years as the Chief Engineer and Director, Jon retired in December, Jon developed the District s User Charge program and billing system. His work in this area resulted in his recognition as an expert in the field of service rate development. Jon also developed the District s Sewer Use Ordinance and worked with all of the District s municipal customers to help them to develop similar ordinances to protect their systems as well as the District s collection system and treatment plant. Jon worked closely with the Department of Natural Resources grants and loan programs to obtain the financing to construct numerous additions to the treatment plant and collection system. He also worked closely with the Dane County Regional Planning Commission on long range studies for interceptor expansions. Jon served for over 30 years with the National Association of Clean Water Agencies (NACWA), formerly the Association of Metropolitan Sewerage Agencies. In addition to serving on the Board of Directors of NACWA, Jon was the author of two national financial surveys and produced the national sewer service charge survey for ten years. As the District s Chief Engineer and Director, Jon oversaw several treatment plant expansions, numerous collection system upgrades, the District s 50-year Master Planning effort, the District s responses to increasingly stringent phosphorous limits, and most recently, the development of Leadership Expectations for the District staff. We will miss Jon s leadership and calm personality. 3

5 ORGANIZATION Madison Metropolitan Sewerage District (the District) is a body corporate with the powers of a municipal corporation for the purpose of carrying out the provisions of Sections to of the State of Wisconsin statutes. It was created by judgment of the county court for Dane County, entered on the 8th day of February Its existence was validated and confirmed by Chapter 132 of the Laws of 1969, effective August 2, The constitutionality of that Law was sustained by the Wisconsin Supreme Court in Madison Metropolitan Sewerage District vs. Stein, 47 Wis. 2nd 349, 177 N.W. 2nd 131 (1969). Time and Place of Meetings The Commissioners of the District meet once or twice each month, at the office of the Commission at 1610 Moorland Road, Madison, Wisconsin. Special meetings are held upon call of any member of the Commission. Commissioners and Executive Staff The District is governed by five Commissioners, each appointed by the Dane County Executive and approved by the County Board for five-year terms. John Hendrick (term ending June 30, 2011) Edward V. Schten (term ending June 30, 2012) Caryl E. Terrell (term ending June 30, 2013) Ezra Meyer (term ending June 30, 2014) Thomas D. Hovel (term ending June 30, 2015) Jon W. Schellpfeffer served as the Chief Engineer and Director until his retirement at the end of In December, the Commissioners announced that they had selected D. Michael Mucha as the next Chief Engineer and Director and that he would begin that role in early to mid-january Dave Gawenda, the Treasurer of the City of Madison serves as treasurer of the District.

7 Sources of Wastewater OPERATION OF WASTEWATER FACILITIES The District receives and treats wastewater from the Cities of Fitchburg, Madison, Middleton, Monona and Verona; the Villages of Cottage Grove, Dane, DeForest, Maple Bluff, McFarland, Shorewood Hills and Waunakee; and from sanitary and utility Districts and other areas in the Towns of Blooming Grove, Burke, Dunn, Madison, Middleton, Pleasant Springs, Verona, Vienna, Westport and Windsor. The District also accepts septic tank wastes and similar wastes from unsewered areas located primarily in rural Dane County. The total area of the District is square miles. Interceptor Service The District provides interceptor sewer service through main and intercepting sewers. The District operated and maintained miles of gravity sewers and miles of raw wastewater force main at the end of Cities, villages and town sanitary and utility districts own and operate the wastewater collection systems that connect to the Districts interceptor system. The District treats all wastewater at the Nine Springs Wastewater Treatment Plant located at 1610 Moorland Road, Madison, Wisconsin, located approximately one mile south of Lake Monona. The easterly part of the District is served by the East Interceptor, the Southeast Interceptor, the Northeast Interceptor and the Far East Interceptor. The westerly part of the District is served by the Lower Badger Mill Creek Interceptor, the West Interceptor, the Southwest Interceptor, the South Interceptor, and the Nine Springs Valley Interceptor. The transmission of wastewater from the metropolitan area to the Nine Springs Wastewater Treatment Plant requires the operation of 129 pumping stations, not including 429 small grinder pump installations. The following two tables list the number of pumping stations operated and maintained by individual communities and the District.

10 Preliminary treatment includes influent wastewater fine screening and grit removal. Fine screening is accomplished with three rotating band screens with 5 mm openings and a vortex grit system is used for grit removal. Variable speed drives for the band screens are used to control the influent well level and to maintain a minimum level above the influent flow meters. Grit is removed continuously from three vortex grit chambers. The dewatered grit and screenings are conveyed to dumpsters and hauled by a contractor to landfill three to five times per week. All material removed by the fine screens is conveyed to a screenings processing well. Two to four times a day the grit must be removed from the well with an operator present to oversee the pumping operation. The grit and accompanying rags are pumped to a separate settling basin (termed a Snail ) which had previously been used by the District in a primary sludge degritting process. The material settled in the snail is conveyed to the larger dumpsters with grit and screenings. Improvements to the fine screening operation were under investigation in A 30 psi spray bar with nozzles continually sprays the rotating 5 mm openings on the screens to push debris into a sluicing channel, and prevents the debris from continuing to the effluent side of the screen. It was found that the spray nozzles were not covering the entire screen and leaving areas were rags and debris were pushing through to the effluent side of the screen. New nozzle configurations were being tested with the manufacturer s assistance to mitigate the problem. Following preliminary treatment, nineteen primary settling tanks are used to remove floatable and settleable material from the wastewater. The wastewater from primary settling is then biologically treated in the activated sludge system. The activated sludge system consists of tanks with anaerobic, anoxic and aerobic zones configured for biological phosphorus removal, ammonia removal and decomposition of organic material. The secondary clarifiers are a combination of center feed/peripheral draw off and peripheral feed/peripheral draw off configurations and efficiently remove the suspended bacterial solids to meet advanced secondary standards. Most of the solids, which contain the microbial culture, are pumped back to the aeration tanks. A certain percentage is wasted every day to maintain a desired bacterial growth rate. An eight-to ten-day solids retention time is normally maintained in the process. During 2010, the secondary portion of the Nine Springs Wastewater Treatment Plant was operated as four separate plants. Effluent from the individual plants was monitored to ensure adequate process control and to provide information on differing operating modes. The treated water is disinfected by ultraviolet irradiation from April 15 th through October 15 th and pumped to Badfish Creek and Badger Mill Creek. In 2010, approximately million gallons per day (mgd) on average were pumped to Badfish Creek and 3.57 mgd were pumped to Badger Mill Creek. The open-channel ultraviolet disinfection system has met the effluent fecal coliform concentration standard since start-up in All lamp banks are cleaned with citric acid in the winter months when disinfection is not required. Lamp and ballast replacement is also accomplished during this period. The primary sludge is removed from the 19 primary settling tanks on a continuous basis and pumped to two gravity-thickener tanks. The solids concentration from the gravity thickeners averaged 4.4% in The waste-activated sludge is thickened in two dissolved-air-flotation (DAF) units. The solids concentration from these units averaged 4.2% in When a new gravity belt thickener was added in 2006 for thickening anaerobically digested sludge, the 9

11 existing gravity belt was modified so it could either thicken waste-activated sludge or anaerobically digested sludge. From January to July, 2010, a portion of the waste-activated sludge was thickened to approximately 5.0% on the GBT to relieve the loadings to the DAF thickeners. The anaerobic digestion process was operated as a single-stage mesophilic digestion system throughout All digesters were fed and heated to a temperature of approximately 100 degrees Fahrenheit. Digester foaming problems plagued the digestion system from January until June, This has been a winter problem since the late 1990 s. Operation with an acid phase digester preceding temperature phased thermophilic/mesophilic digesters was attempted in 2007 and This followed the 10 th Addition digestion system modifications as a way to address the foaming problem. However, due to several operational problems, the configuration was abandoned. The detailed design phase of the 11 th Addition for further upgrades to the digestion system was in progress in 2010, but interim operation as a single-stage mesophilic digestion system will continue until upgrades are made to the system. In an attempt to mitigate the digester foaming problem, piping additions were completed in November 2009, which allowed a different feeding pattern for the digesters. 100% of the primary sludge and less than 50% of the waste-activated sludge were fed to the east digesters which have gas mixing systems. The remainder of the waste activated sludge was fed to the west digesters along with some of the effluent sludge from the east digesters. The west digesters have less capacity, but have mechanically mixed systems less susceptible to foaming. The purpose of this feeding method was to reduce the foaming problem in the east, gas mixed digesters. This feeding pattern was implemented and continued throughout The digested biosolids concentration averaged 2.4% in The digested biosolids were thickened from 2.4% to an average concentration of 5.8% by the addition of polymer on gravity belt thickener # 2. An average of 22.5 tons/day of digested biosolids was thickened in The polymer used for thickening was a liquid emulsion polymer. The thickened and digested biosolids are either pumped directly to loading facilities or to the Metrogro storage tanks. During the winter, all biosolids are stored in the Metrogro storage tanks. The tanks have a storage capacity of 19.5 million gallons. All biosolids are hauled and applied to cropland as a soil conditioner and fertilizer. The digested biosolids are marketed by the District under the name of Metrogro. As a by-product of the anaerobic digestion process, gas is produced that is approximately 60% methane. The District supplements digester gas production with natural gas purchased from Madison Gas and Electric. Digester gas usage averaged 636,000 cubic feet per day in Part of the digester gas was used to fuel boilers for plant heating and to fuel a 650 horsepower blower engine, which provides air to aeration tanks. The remainder of the gas is used to fuel two generator engines in Sludge Control Building #2. Prior to use in the engines and boilers, the gas is treated by a gas treatment system started up in May The gas treatment system removes moisture, hydrogen sulfide and siloxanes from the gas. An average of 14,256 kw-hrs of electricity was generated each day in 2010; and the engine blower saved the purchase of approximately 4,460 kw-hrs per day of electrical energy. The District takes advantage of the heat recovered from the engines to heat anaerobic digesters and most plant buildings. Jacket water heat and engine exhaust heat are recovered from all three engines when available. Lube oil heat is recovered from the generator engines, but not from the blower engine. 10

12 All three engines were shut down in December 2010, when the District discovered WDNR air emission operating permits were required for the engines and boilers. Based on the size of the engines and the amount of fuel being used in them, WDNR felt that a construction permit should have been obtained at the time that the engines were installed in Modeling and testing were required for determination of emission limits for engine operation. Until limits could be determined, and modifications made to assure those limits could be met, the District decided only plant boilers would be operated to provide heat for the buildings and digesters. The District hired the firm of RMT, Inc. to submit a permit application. The District also retained attorney Linda Bochert of Michael Best & Friedrich, LLP to represent the District in future negotiations with DNR. A preliminary permit application was submitted to DNR in November and a stack emissions test was performed on one of the engines in January An update to the permit application is expected to be submitted in March Since preliminary modeling indicated that the exhaust stacks on the engines would need to be raised, Strand Engineers, Inc. was hired to provide structural plans to support the extended stacks. The DNR has determined that a number of other treatment plants in the State may also be operating combustion equipment without a permit. Representatives of the District have been meeting with DNR staff and representatives of the Racine Water and Wastewater Utility to develop a survey that will be sent to all treatment plants in the State. This survey will be used by DNR to establish categories of facilities and emission thresholds to define which facilities are exempt from the requirement to obtain an air permit and which facilities need an air permit. The 2010 wastewater treatment data are reported in accordance with the District s WPDES Permit and a summary of this information is shown in the table Yearly Log-Plant Operations. Monitoring data for effluent metals are reported in the table Influent and Effluent Metal Concentrations. 11

Environmental monitoring to support the Metrogro program continued in Approximately 650 water samples were collected from private wells, with samples being analyzed for a number of parameters, including nitrate nitrogen and coliform bacteria. Soil samples were also collected, with the soil test recommendations being used to determine Metrogro application rates. 13

15 A change was made to the spring yield guarantee program in 2009 in an effort to control costs. A standard payment structure was instituted based on the date at which application to a given field is completed. This change was made in an effort to control costs. Payments in 2010 were 12% less than payments in This reduction was mainly due to most of the spring application of biosolids being completed by May 15 th. MetroMix Program The District s goal is to diversify its overall biosolids management program by developing a soillike product(s) called MetroMix. MetroMix will be produced by combining dewatered biosolids with materials such as sand and sawdust to provide bulk and texture. Wide scale production and distribution of MetroMix will not occur until after completion of the 11 th Addition to the Nine Springs Wastewater Treatment Plant. The District is in the research and development phase of the MetroMix Program. The District is providing laboratory support and other in-kind contributions for a 4 year field research project being conducted jointly by the University of Wisconsin-Madison and the Virginia Polytechnic Institute and State University (Virginia Tech) that is funded by USDA. This project is evaluating use of biosolids (including MetroMix) in sod production as an alternative to traditional production systems that use commercial fertilizer. Specific research objectives include the following: Evaluating the agronomic benefits or drawbacks to using biosolids, composted biosolids, or de-watered biosolids for sod production compared to traditional production systems. Quantifying soil loss or gain during traditional and biosolids-based sod production and harvesting. Determining short and long term impacts of using biosolids for sod production on soil physical, chemical, and biological properties. Quantifying changes in fertilizer and pesticide inputs along with disease and insect pest susceptibilities. Calculating the economic advantages or disadvantages of using biosolids for sod production compared to traditional methods. Identifying the potential social barriers to producer and consumer acceptance of sod grown using biosolids and identifying how potential barriers might be overcome. Should the economics and other issues associated with biosolids use for sod production prove to be favorable, a seventh objective of this project would be to develop a comprehensive outreach program to communicate the results of this project to stakeholders and to facilitate the adoption of more economically and environmentally sustainable sod production systems throughout the United States. Biosolids were initially applied to the research plots in the fall of 2009, with a second application being made in the fall of Preliminary data is promising, showing that biosolids applied at high rates produced sod with color, density, and quality similar to or better than the fertilized controls. 14

16 ACCOUNTING AND CLERICAL ACTIVITIES The District s Accounting/Clerical work group provides clerical support and accounting functions for all District departments. Routine tasks include receptionist duties; telephone answering; typing of commission meeting minutes, agenda and resolutions; managing the septage receiving database; records management including scanning incoming and outgoing general office correspondence for electronic storage; and accounting functions including administering accounts receivable, accounts payable, general ledger, payroll, investments and employee benefits. Notable activities in 2010 include the following: 1. Joyce Williams joined the Accounting Department staff in December This enabled Stephanie Calkins to get involved in higher level accounting duties and Janelle Werner to dedicate additional time to OnBase (Electronic document retention system) support. Stephanie and Janelle were also involved in more of the business planning for the department and helped to establish training plans for their additional responsibilities. Debi Iglesias assisted in implementing new workflows for OnBase scanning and created outlines and flow charts for the structure in OnBase. Debi has been putting more of our permanent documents, such as Commission meeting minutes into OnBase for retention. 2. The OnBase document management system continued to be a focus area in We completed scanning employee-reviewable human resource records into OnBase, and gave employees access to their own information. This allows employees to view information such as personal development plans and records, performance review documents, pay and tax information, and current benefits. We also worked with the Engineering department to document their workflows for OnBase and improve the workflow for pay requests and consultant invoices. 3. Asset Management was a focus for the group in Since the CMMS system now has asset depreciation functionality available, we plan to import our FAMS (current depreciation system) assets into CMMS. With the help of several people we have matched up asset to asset and populated all necessary fields for import. Once completed, this will make future asset additions, retirements, and write-offs much easier and will also provide more information for asset replacement and capital budget. All of the worksheets of District assets have been converted to an electronic form which is searchable by project. INFORMATION SYSTEMS ACTIVITY The District s Information Technology (IT) workgroup provides infrastructure support and the Information Systems (IS) workgroup provides software support for the following existing applications: Administration: Budgeting, Document and Records Management, , Microsoft Office Desktop, Pretreatment, Pump Station Billing, Rate Setting, Security, User Change Billing, and Web Site Management. 15

17 Engineering: Change Order Management, Construction Plan Holders, Geographical Information System (GIS), and Hydrology Modeling. Operations & Maintenance: Metrogro Hauling and Land Application, Operations (Regulatory) Reporting, Laboratory Analysis, Process Control Data Transfer and Analysis, Oracle Work and Asset Management. The Staff were also involved in the following activities in 2010: An upgrade to the Oracle Work and Asset Management (Work Order, Purchasing, and Timekeeping) system was completed. The IS staff continue to make software improvements to the in-house Lab Information Management System (LIMS) application. The telephone system was upgraded. Normal budgeted replacement of servers, PCs, and laptops RESEARCH UW Soils Department/State Laboratory of Hygiene Research A long term objective of the District is to produce a biosolid that meets the USEPA and Wisconsin Department of Natural Resources definition of a Class A biosolid with respect to pathogens. Class A production requires the use of a treatment process that consistently reduces pathogens to below detectable levels. Current state and federal regulations require the production of a Class A biosolid for end uses anticipated in the MetroMix Program. Regulatory agencies have identified six different methods that can be used to demonstrate compliance with the Class A pathogen reduction requirements. One method is to demonstrate on a site-specific basis that operating conditions result in pathogen reduction levels equivalent to defined processes known to reduce pathogen levels to below detectable levels, which are commonly referred to as processes to further reduce pathogens (PFRPs). In order to obtain PFRP equivalency, a facility must demonstrate that its process is capable of achieving a 3 log inactivation of fecal coliforms with final density <1,000 MPN/g dry wt, a 3 log inactivation of enteric viruses, and a 2 log inactivation of helminth ova. This must be done both at the laboratory-scale and full-scale. In the U.S., viruses and helminth ova are often present at such low levels that this degree of inactivation cannot be demonstrated from natural incoming levels. Quarterly sampling of digester feed and digested biosolids indicates that this is the case for the District. Research being led by Professor Sharon Long (UW-Madison/Wisconsin State Laboratory of Hygiene) is exploring whether appropriate surrogates can be identified for virus and helminth ova. If the surrogates are demonstrated to correlate with spiked pathogens at the laboratory scale, those surrogates can be tested at full scale and the relationship with pathogens can be used to support that the required degree of pathogen inactivation for a Class A determination is being obtained. Since surrogate organisms can be enumerated more rapidly than pathogens, testing for them would also allow for more frequent process monitoring. 16

18 Results to date suggest that, male-specific coliphages and enterococci may be useful as surrogates for virus destruction. Surrogates have yet to be identified that correlate well with helminth ova destruction. Work will continue on this project in MMSD Golf Course Demonstration Project Working in cooperation with the City of Fitchburg and the Nine Springs Golf Course, effluent is being used to irrigate a 5,200 square foot area on the 7 th hole of the golf course, which includes the former green and portions of the adjacent fairway. This demonstration project began in 2004 as part of the District s on-going effort to evaluate opportunities to promote the beneficial reuse of effluent. The following table shows various application statistics for the past five years.

District staff will explore opportunities to expand the irrigation project to a larger portion of the golf course in Groundwater Recharge MMSD recently completed a 50-year master plan. Two recommendations from the planning effort were that the District should consider watershed balancing and opportunities for effluent reuse in future facilities planning projects. One potential approach to accomplish both watershed balancing and effluent reuse is to use highly treated effluent for groundwater recharge. 17

19 The District, in partnership with the City of Fitchburg, supports a yearlong practicum (2010/2011 school year) conducted by the University of Wisconsin-Madison Water Resources Program that is exploring opportunities for groundwater recharge. Students participating in the practicum are examining a wide range of engineering, water quality, regulatory, and social issues that need to be considered before a potential groundwater recharge project could move forward. Much of the focus during the first semester was spent on collecting baseline information and conducting a literature review. Specific tasks moving forward include the following: Identifying desired site characteristics (soil physical properties, etc) and using these characteristics to identify preferred sites within the City of Fitchburg. Evaluating potential impacts on water quality and quantity (including impacts on groundwater levels). Evaluating the current regulatory structure to determine if changes are needed to ensure that recharge is conducted in a manner that protects human health and environmental quality. Developing a generic design for a recharge project, including planning-level cost estimates. Identifying social barriers to a potential groundwater recharge project and identifying specific information/education/outreach efforts to effectively address these barriers. UW Engineering Department/Struvite Control In 2010, under the direction of Professor Daniel Noguera of the UW Civil and Environmental Engineering Department, graduate student Cheng Ji conducted research to investigate the reduction in struvite formation in anaerobic digesters following Waste Activated Sludge (WAS) phosphorus release before digestion. Two digester trains were operated for this study. One train digested WAS combined with primary sludge and no special treatment, the other digested WAS from which the phosphorus had been released and primary sludge. This portion of the study demonstrated that releasing phosphorus from WAS prior to anaerobic digestion resulted in phosphorus levels inside the digester about 10-15% lower than that from digesters fed with untreated WAS. Also examined in this research are the effects of cooling the sludges and understanding the precipitates that are formed. This was a significant problem first observed during 10 th Addition operation of tube and shell heat exchangers used for cooling thermophilic sludge to mesophilic temperatures. Constant heat exchanger cleaning was required to remove what was assumed to be struvite from the heat exchanger tubes. The purpose of the research is to understand the precipitation reaction associated with cooling of thermophilic sludge to mesophilic temperatures so the precipitation can be reduced or better controlled. With research still under way at the end of the year, it appears that the previous assumption of struvite being virtually the only precipitant associated with digested sludge cooling may have been incorrect. Other related, but different precipitants, may be formed during sludge cool down. Work is continuing in this area to collect more data, confirm early observations, and to better understand the processes involved. UW Engineering Department/Digester Foaming Under the direction of Sharon Long of the UW College of Agriculture and Life Sciences, graduate student Amanda Siebels investigated causes and potential cures for anaerobic digester 18

20 foaming experienced at the Nine Springs Wastewater treatment plant. Foaming in the digesters has been a serious operational problem since the late 1990 s. The foam has the potential to cause extensive damage to the digester and gas handling equipment. Various test methods were developed for measuring the foaming potential in the digesters and in the feed sludge, and biological tests were under development for identifying filamentous bacteria normally associated with foaming. Testing was conducted November 2009 through April 2010, on bench-scale mesophilic and series acid-phase/thermophilic digesters to evaluate the process impacts on foaming potential. The research confirmed that time of year and the quality of the feed solids were the most important factors in triggering of our foam events, based on the observations of the bench scale digesters. The research also concluded that while the acidphase/thermophillic digester combination was successful in decreasing filamentous organisms, due to the presence of the destroyed cell walls, the foaming potential was not reduced, and in fact was shown in the lab to have increased foaming potential. Since this research can only be effectively done while the Nine Springs plant is experiencing foaming, bench research was suspended during the summer months and was re-started in mid- November. The purpose of this phase of research will be to investigate mitigation techniques in light of the findings from the previous work. Phosphorus Release from Waste Activated Sludge (WAS) Research work continued using in-house staff and laboratory resources to evaluate possible alternatives to the phosphorus release method proposed by the University research, which was the combination of the WAS and primary sludges to release phosphorus. This applied research work demonstrated at bench scale that introduction of a small recycle stream of acid phase digester sludge to the WAS is capable of a higher phosphorus release percentage than combining WAS and primary sludge. Added benefits of this method of phosphorus release are decreased liquid volume to thicken (and thus less equipment required) and a more concentrated phosphorus stream to send to the harvesting equipment being added in the 11 th Addition upgrade. Based on this bench-scale work, design for the 11 th Addition is proceeding around this method as the primary basis for reducing phosphorus prior to anaerobic digestion. Additional work in this area during the year determined that addition of a small amount of a supplement (similar to molasses) from Quality Liquid Feeds (QLF) is capable of equaling the observed release percentage obtained from acid phase sludge addition. Unlike acid phase digester sludge which is being designed into the 11 th Addition and will be available on-site the QLF supplement (or similar) if used would need to be purchased and transported in. However, it does appear, based on bench scale work, that it will offer another viable option for operation if acid phase sludge cannot be used for any reason. Research evaluating the effectiveness of a combination of acid phase digester sludge and QLF appears to show at bench-scale that it may offer even greater effectiveness than either additive independently. 19

21 INDUSTRIAL PRETREATMENT PROGRAM In 2010, the Industrial Pretreatment Program continued to implement state and federal requirements regarding permitting activities directed towards industrial users. Additionally, pollution prevention and source control measures continued to serve as vital components of the working relationships with non-permitted users. Industrial permits for Carnes Company, Fristam Pumps USA, Placon Corp., and Bell Laboratories were all reissued. All industrial permittees received annual inspections, and District-led compliance monitoring of regulated wastewater discharges occurred in both semiannual periods. No third party or regulatory audits of the pretreatment program were conducted in District staff continued to perform waste-acceptance reviews and to respond to non-permitted industrial, hauled waste, and other waste acceptance requests. Septage permits were issued to several new waste haulers and annual septage permits were reissued to more than 30 hauling companies. Eleven mid-level (NTO) permits were reissued to entities including landfill owners and industrial/institutional dischargers. Pollution prevention efforts continued to focus on mercury with some outreach directed towards future chloride reduction measures. Activities in the fourth year of the Mercury Pollutant Minimization Plan remained focused on the dental sector. Over 100 dental clinics, where dental amalgam is placed or removed, continued to operate amalgam separation equipment. The fourth annual report of dental best management practices by dental clinics resulted in improved response rates over previous years. Additional dental sector activities included performing site visits at 20 dental clinics. District staff performed site visits at hospitals and UW Madison to support mercury minimization activities at those institutions. ACCEPTANCE OF SEPTAGE AND ATYPICAL WASTES Septage has been accepted at Nine Springs Wastewater Treatment Plant since During 2010, the District accepted waste from 21 permitted septage haulers and six non-typical haulers (organizations or consultants) via special discharge permits. The septage receiving facility handled nearly 9,500 loads in The septage haulers are charged a specific rate for each category of septage that reflects the District s cost of treating the wastes. The following table lists the five domestic septage categories, the number of gallons of septage received during 2010 and the percent of increase or decrease in volume from 2009 to Septage Types Received, Summary Information Septic Tank Holding Tank Grease Trap Settling Basin Portable Toilet 7,167,000 14,430, , , ,000 32% increase 15% increase 6% decrease 10% decrease 2% decrease The septage receiving facility is the discharge point for other wastewater not characterized by the five domestic categories. During 2010, other wastewater included: 20

22 Other Wastes Volume (Gallons) Groundwater from Remediation Projects 15,600 Refuse Hideaway Landfill Leachate 476,000 Middleton Landfill Leachate 16,000 Verona Landfill Leachate 69,000 Ice Cream from Schoep s 148,000 Annatto Oil Residue from Danisco USA 4,500 Tissue Digester Residue from WVDL 32,000 Diluted Glycol from HVAC Contractors 11,000 Other Industrial Wastewater 3,000 The District continued cooperative efforts with regional wastewater treatment plants by providing transportation and treatment services for biosolids. The District transported 84 loads of biosolids from the Village of Brooklyn totaling 413,000 gallons and 134 loads of biosolids from the Village of Belleville totaling 666,000 gallons. Other wastewater generated outside of the District service area and transported by permitted septage haulers included: 95,000 gallons of pet food manufacturing waste from NFP of rural Lake Mills, and 613,000 gallons of meat packing wastewater from Dairyland Beef of rural Cottage Grove and Country Meat Cutters of rural Reeseville. Acceptance of wastewater generated outside of the District is in accordance with District policy, and generators are assessed surcharges that escalate quarterly. LAGOON SITE SUPERFUND PROJECT Routine O&M activities continued in These activities included monthly visual inspections of capped areas and containment dikes, dike stability monitoring, water management and vegetation control. The cap continues to perform as intended and routine O&M activities will continue in The District received permission from EPA to move from a semi-annual reporting frequency to an annual reporting frequency. EPA agreed that a reduced reporting frequency is warranted given the low maintenance requirements and the low level of activity associated with the capped area. EPA also determined that dike stability monitoring using sondex and inclinometer instrumentation only needs to be conducted during times when significant work takes place (e.g. raising dike elevations as part of routine maintenance). WATERSHED PROJECTS Yahara River Watershed Monitoring Program Monitoring to determine the impact of the District s treated discharge upon the main receiving stream, Badfish Creek, continued in During 2010, water-quality sampling of Badfish Creek, its tributaries and the Yahara and Rock Rivers continued semi-annually at established sampling points. 21

23 Aquatic macroinvertebrate samples were collected from three sites on Badfish Creek and one site on the Oregon Branch of Badfish Creek twice during 2010 (April and October). Three samples were taken at each site, producing a total of 24 samples. Biological indices continue to suggest that the District s effluent water quality is not inhibiting organisms from living in Badfish Creek. Preliminary data show fair to good water quality classification for all sites. Staff collected fish at three sites along Badfish Creek in July using the District s walk-along, stream-shocking boat. Each site sampled had four 100-yard sections shocked for data analysis. Results continue to show a diverse population of fish inhabiting Badfish Creek. A total of 45 different species of fish has been collected since fish shocking was started in 1983, with 19 22

24 species being collected in At Site 1, northern pike were again collected being found 5 of the last 6 surveys at this uppermost site on Badfish Creek. Twenty-six brown trout were collected at Site 2 which is the most collected since the inception of fish shocking in May The blacknose dace, brown trout, hornyhead chub, white sucker, and golden shiner all showed an increase in the collections during this survey at Site 3. The green sunfish was again the dominant fish collected at Site 1. At Sites 2 and 3, the white sucker was again dominant. The information collected continues to suggest that water quality is not a limiting factor in the viability of fish living throughout Badfish Creek. The lack of fish habitat and the addition of non-point pollution sources along the 20 miles of Creek, may continue to cause fewer game fish and other fish species to be collected during future surveys. The aquatic plant, Eurasian water milfoil, was seen for the sixth year at all fish shocking sites. There is a concern that this species of aquatic plant will form dense mats on the surface of the water, affecting dissolved oxygen values which are critical for the survival of fish and other aquatic life. Eurasian water milfoil is now quite prevalent at Site 2. This highly invasive exotic plant will be closely monitored during future surveys. 23

25 Sugar River and Badger Mill Creek Monitoring Program The Sugar River and Badger Mill Creek, both within the Sugar River Watershed, were sampled chemically and biologically in 2010 to determine water quality. During 2010, water samples were collected bimonthly at established sites within the watershed and chemically analyzed. Aquatic macroinvertebrates were collected at two sites on the Sugar River and three sites on Badger Mill Creek in April and October. Aquatic macroinvertebrates were collected similarly to 24

26 the ones in Badfish Creek with three kick samples taken at each site, producing 30 samples. Preliminary data for 2010 show a fair-to-good macroinvertebrate community at all of the sites, which is similar to A fish survey completed in July used the District s walk-along stream-shocking boat on four 100- yard sections at two sites on Badger Mill Creek and two sites on the Sugar River. This survey produced 23 different species of fish. Since 1994, there have been 39 species of fish found in the Sugar River Watershed; 29 species in Badger Mill Creek and 36 species in the Sugar River. The brown trout had the 2nd greatest number of individuals collected at all sites since 1994 (346). Water chemistry has not changed; however, stream habitat (substrate) appears to be changing from a more coarse gravel to a finer-grained mud. It is recommended for future studies to use the same shocking crews to aid in data analysis. 25

27 Upper Yahara River Watershed Monitoring Program In July 2002, monthly water sampling was initiated in the Upper Yahara River Watershed on Token Creek, Six Mile Creek, Spring Creek and the Yahara River. For each water body, water 26

28 samples were taken at sites near their headwaters and at sites closest to their entrance to Lake Mendota. Samples were taken to characterize water quality conditions in the Upper Yahara River Watershed. In July 2003, after a year of monthly testing, sampling was reduced to quarterly. The number of sample sites was also reduced, with remaining sampling taking place closest to each stream entry to Lake Mendota. During 2009, four samples were taken at these sites. Results continue to show similar values for the twenty-three chemical parameters monitored. Sites have also been chosen for fish and aquatic macroinvertebrate sampling, although no collections were made in Grass Lake Monitoring Program Numerous times during the year, relief operators and the District Biologist went to the Grass Lake dike to monitor its integrity and gather water level information from the lake and the Badfish Creek effluent channel. Although water sampling was discontinued in 1995, the District still monitors lake levels and maintains the dike as required by the NR permit issued by the Department of Natural Resources in Phosphorus-Related Initiatives The Natural Resources Board adopted administrative rule revisions related to phosphorus in June 2010, that are collectively aimed at controlling phosphorus discharges to waters of the state. These revisions included establishing numeric water quality criteria for phosphorus, developing an implementation framework for point dischargers, and establishing new provisions to control runoff from nonpoint sources. In a separate effort, the Wisconsin Department of Natural Resources (WDNR) and EPA have jointly issued a draft Total Maximum Daily Load (TMDL) for phosphorus and total suspended solids for the Rock River Basin. A TMDL is a calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards. The TMDL allocates the pollutant load between point sources and nonpoint sources. DNR has also begun to develop an implementation plan for the TMDL, with assistance from stakeholder groups. District staff are participating in the development of the implementation plan. These phosphorus-related initiatives will impact the District by requiring that phosphorus loads associated with effluent discharge either be reduced by adding advanced treatment at the Nine Springs Plant, offset through water quality trading, or addressed using a combination of these approaches. The Natural Resources Board also directed DNR staff to develop a statewide framework to support water quality trading. DNR formed a workgroup to provide assistance in developing this framework, and District staff is participating in this effort. The District, in cooperation with Dane County, also formed a workgroup to help evaluate opportunities for trading at the local level. MONITORING STREAM FLOWS An agreement signed in June 1977, with the United States Geological Survey (USGS) for monitoring stream flows in Badfish Creek near Cooksville and the Yahara River near Fulton, was renewed for another year. In September 1996, an agreement was also signed with the USGS to monitor stream flows, stage, specific conductance, dissolved oxygen and water temperatures in Badger Mill Creek near Bruce Street in Verona. This agreement was also renewed for another 27

29 year. In April 2009, a new monitoring site was added to the Sugar River at HY 69 near Verona. This site monitors stream flows, stage, specific conductance, dissolved oxygen, water temperatures and ph. LABORATORY ACTIVITIES During 2010 the District Laboratory performed a total of 61,005 analyses on 13,100 samples. These analyses included: PARAMETERS QUANTITY Nutrients (TKN, TP, NH3-N, NO2-N, PO4-P, WEP) 17,899 Solids (Suspended and Total) 16,348 Biochemical Oxygen Demand 5,201 Anions (C1, NO3-N, SO4) 4,002 Field Measurements (ph, TEMP, COND, DO) 4,247 Metals 9,021 Bacteria (FCOLI, TCOLI, ECOLI, Salmonella) 1,436 Volatile Fatty Acids (VFA) 1,781 Misc. Testing (Alkalinity, Density, Oil and Grease, CN, WET) 1,070 The District laboratory was also involved in the following activities: Continuing its relationship with the UW and providing analytical support on three UW research projects. One project was designed to assess the performance of anaerobic digesters fed normal sludge versus anaerobic digesters fed phosphorus-released sludge. The second study was designed to assess the issue of foaming in the digesters. The third study is a research project conducted by the UW-Soils Department that is evaluating the use of biosolids to support turf production. These studies will continue into Analyzing numerous samples in support of in-house research to help determine the efficiency of phosphorus release using acid sludge. Analyzing samples from the City of Middleton for TKN, NH3-N and TSS analysis. During wet weather conditions, the city pumps water out of a retention pond and must have the discharged water analyzed for reporting to the DNR. During the year the District analyzed twelve samples of this type. Analyzing samples from the City of Madison Engineering Department from their monitoring program. The City collects samples from various points throughout the collection system to use for billing purposes. The District analyzed 137 samples for TKN, TP, CBOD5, TSS, and ph. This partnership will continue in MAINTENANCE OF DISTRICT FACILITIES The maintenance workgroups of the Operations and Maintenance Department are responsible for the maintenance of the Nine Springs Wastewater Treatment Plant, the District pumping stations, the non-district pumping stations covered by maintenance agreements, and the District s interceptor system. This work is performed by the Mechanical Maintenance Section, the Electrical Maintenance Section, the Building and Grounds Section, the Monitoring Services/Sewer Maintenance Section, and the Purchasing/Inventory Section. 28

30 Training of craftsmen continued to be an important function in Maintenance Department personnel serve on the Joint Apprenticeship Training Committee (JATC) which oversees the activities of the apprenticeship programs for electricians and mechanics. Additional training courses attended by Maintenance Department supervisors and craftsmen included: MMSD Supervisory Training Program, Underground Storage Tank Operator training, Full Circle WAM user conference, Smart Pressure Transmitter training, and the Collection System Seminar Following are more detailed listings of the activities performed by each of the maintenance sections. Building and Grounds Section The section spent the majority of the year maintaining the District and non-district pumping stations and the Nine Springs Wastewater Treatment Plant buildings and grounds, odor control equipment, roads, and small equipment. Routine work includes landscaping projects, cutting grass, plowing snow, cleaning plant buildings and galleries, maintaining lagoon and dike roads, and painting and carpentry projects. This section performs preventive maintenance work on the District s electrical manholes, process tanks, roofs, floors, and HVAC units. There were significant personnel changes within the Building and Grounds Section in Early in the year, Art Errthum moved to an Apprentice Electrician position and Steve Klein moved to an Apprentice Mechanic position. Ross Hollfelder, Brady Lessner, and Jeremy Olson joined the District with the Building and Grounds crew in March. In 2010, the Building and Grounds Crew assisted the Operations and Engineering staff with various projects. Major projects accomplished in 2010 were: Cleared trees off of the Grass Lake Dike. Continued working with the City of Madison on a non-intrusive well cleaning procedure. The procedure minimizes entry into confined spaces and allows the grease that is removed to be taken directly to the landfill. Performed preventive maintenance on Primary Tanks 1, 2, 13, and 14. Performed preventive maintenance on Aeration Tanks 1 through 9. Performed preventive maintenance on Final Clarifiers 1, 2, and 7. Painted and landscaped at the treatment plant.

Replaced the septic system tank for the District property at 1243 Moorland Road Mechanical Maintenance Section The goals of the Mechanical Maintenance Section are to: 1) verify proper operation and effectively maintain the pumping stations of the District and its contract customers; 2) ensure that all collected wastewater is conveyed to the treatment plant; 3) effectively maintain and support operation of the treatment plant equipment and facilities while working with operations personnel to meet the District s goal of meeting or exceeding the WPDES permit; and 4) develop section staff members to their best professional and personal ability through the District s apprenticeship program, other training programs, and wellness opportunities. Mark Ripp completed his apprenticeship and became a journeyman maintenance mechanic. Zenon Kochan and Steve Klein were enrolled in the Maintenance Mechanic Apprenticeship Program. They continue to gain valuable work experience by working with the District s journeymen. Three mechanics are also participating in the District s Supervisory Training Program. Several mechanics have begun to work on their Personal Learning Plans. In addition to many planned and scheduled maintenance activities, major accomplishments completed in 2010 included: Removed and reinstalled three effluent cone valves when they were sent for rebuilding. Rebuilt an ACB2 return sludge pump. Repaired digester draft tube mixers and mixing compressors. Rebuilt Pumps A and B at Pump Station 17. Installed two new pumps at the City of Madison Cherokee pump station. Installed one new pump at the City of Madison Atlas pump station. Replaced the compressor at the City of Madison Diemer pump station. Removed and reinstalled the Waukesha blower engine when it was sent out for an overhaul. 30

32 Electrical Maintenance Section The Electrical Maintenance Section devoted a majority of the year to providing the support necessary to assure a high level of electrical reliability to District facilities and the facilities owned by others and maintained by the District. This was accomplished with a mix of preventive maintenance, normal day-to-day support, staff training, and planned improvement and construction projects. Examples of preventive maintenance tasks developed by the section include: calibration of electrical and instrumentation equipment, thermographic testing of switches and motors, repair and testing of fixed and portable gas detectors, and operational inspections and cleaning of electrical and electronic equipment. The section continued to make progress in identifying problems by tracking data with the use of the Computerized Maintenance Management System (CMMS). The CMMS has continued to aid with maintenance scheduling and daily work orders. Steve Hering completed his apprenticeship and received his journey worker certificate. Carl Wright retired from the District. Jeff Kroning and Jeff Fuller continued their progression in the Industrial Electrician Apprenticeship program. Art Errthum joined the electrical maintenance group and enrolled in the apprenticeship program. In addition to normal maintenance tasks connected with the operation of the District s wastewater collection and treatment facilities, the following planned improvements or projects were completed or continued in Completed upgrade of the electrical distribution system and pump controls at the Town of Madison Mayflower Pump Station. Assisted with the rehab projects at District pump stations 6 & 8. Completed the upgrade of the level control system at District Pump Station 7. Assisted with the Process Control System facility planning project. Prepared the pumping station control panels for summer and winter operation. Continued with the upgrading and documentation of electrical drawings for the District and non-district facilities. Provided electrical cross-training to the District s mechanics. Assisted with the startup of City of Madison Midtown pump station. Continued with the in-house training of the apprentice electricians on electrical and instrumentation theory and hardware. Continued updating of the documentation for the District s phone system. Continued to modify the Johnson Control software to accommodate the Operations Building HVAC system. Operated District generators to provide power to various pumping stations during planned and unplanned power outages. Assisted with the operation building HVAC control system rehab project.

Continued with modification of control systems at City of Madison and District lift stations to allow proper station operation when the PLC or UPS has failed. Completed upgrade of Operations Building sump controls. Completed the flow meter replacement for primary effluent flow to Aeration Tank 24. Assisted Mechanical maintenance group with Blower engine and Generator engine removal and rehab. Assisted with the preventive maintenance testing of electrical equipment at the Nine Springs facility and District pump stations. Assisted with the thermographic inspection of electrical equipment at the Nine Springs facility and District pump stations. Inventory Control/Purchasing The primary goal of the Inventory Control/Purchasing Section is to centralize purchasing and inventory control functions for the District to reduce costs. One major component is the scheduling and completing of physical inventories. Three partial inventories were conducted in April, July, and October based on usage. In December, a full physical inventory was conducted to reconcile all inventory quantities. Grouping orders together and taking advantage of price breaks at price and quantity levels have helped to reduce purchasing costs. Internet purchasing is being used to take advantage of the latest technology. Expanding the vendor base and finding alternative sources and products for District purchases have resulted in shorter ordering times and a reduction in District inventory. During 2010 the Inventory Control/Purchasing section performed the following: Took over responsibility for purchasing and inventorying of safety equipment. Assisted with the testing of new releases for the Computerized Maintenance Management System known as WAM Attended the WAM user group conference Received certification as Class A and B underground storage tank operators. Increased the number of parts being manufactured by local machine shops rather than purchasing them from the equipment supplier. Began working with a second machine shop to manufacture replacement parts. Obtained membership in the Madison Plant and Facilities Maintenance Association (PFMA). Monitoring Services/Sewer Maintenance Section Following the retirement of Don Lythjohan, John Podebradsky was selected to fill the Collection System Supervisor position. Later in the year, Derek Steinhorst was selected to fill John s position on the crew. A major portion of the work performed by this section is the collection of wastewater samples and flow information from the communities and sanitary districts that are served by the District. The crew also inspects portions of the District s collection system each year. Repair needs found by the crew are either made by the crew members or by contractors. In addition to the inspections performed by the crew, crewmembers work with contractors to televise and clean portions of the interceptor system. During 2010, the following activities were performed by the crew: 32

34 Inspected and maintained the air relief valves on several of the pumping station forcemains. Worked with the Engineering Department and equipment vendors to determine if modifications could be made to reduce the plugging problems that have been experienced. Made repairs to several manholes that had been damaged by snowplows or mowers. Inspected the following interceptors: o Southeast Interceptor McFarland Relief and Sigglekow Extension o Nine Springs Valley Interceptor Highway 14 Extension, Granada Way leg, and Ski Lane leg o Northeast Interceptor manholes to o West Interceptor Randall Relief o Northeast Interceptor Waunakee Extension Worked with a contractor to smoke test and remove an abandoned line that ran through manholes through Inspected stop log and flap gate structures. Exercised buried valves at several pumping stations. Removed the flow splitting gate in manhole Worked with a contractor to clean the siphons. Installed inside seals on manholes through INTERCEPTOR TELEVISING AND CLEANING MMSD's collection system includes 93 miles of MMSD-owned gravity interceptors and approximately 1,200 manholes. MMSD s interceptor inspection program includes annual cleaning and televising of approximately 10% of this system each year. This program is intended to keep MMSD current on the physical condition and hydraulic adequacy of its interceptors and to allow for well-informed decisions regarding the need for significant underground repair or replacement projects. The 2010 televising and cleaning was performed by Visu Sewer, Inc. The following areas were cleaned and televised: West Interceptor Northeast Interceptor Southeast Interceptor East Interceptor Monona Extension 11,818 ft 1,710 ft 7,810 ft 1,326 ft The contractor must repeat televising for 3,880 ft of the Northeast Interceptor because of technical problems with the recording system. That work will be completed in USER-CHARGE MONITORING AND BILLING User-charge billing of the District s thirty-seven municipal customers is performed quarterly using data collected at Nine Springs Wastewater Treatment Plant and within the collection system. The monitoring services/sewer maintenance (MS/SM) crew supports quarterly billing by providing sampling and flow measurement at key points in the collection system. In 2010, the MS/SM crew collected data and samples at 92 field sampling points each quarter, thereby generating 2704 samples throughout the year. The analysis of the user-charge field samples and Nine Springs influent samples by the District lab generated 12,463 sample results used in the user-charge billing process. 33

35 SEWERAGE SERVICE CHARGES Prior to the beginning of each calendar year, the District furnishes a written estimate of the cost of sewerage service for the ensuing year to each municipality in the District. This estimate is based on the previous year s wastewater contributions, any anticipated changes that may alter the municipality s prevailing water use trends, and the service charge rates for the ensuing year. The District s 2010 service charge rates, shown in the following table, were adopted on October 26, Service Charge Rate Summary Information Parameter Rate Units Volume $ per million gallons CBOD $ per pound Suspended Solids $ per pound TKN-Nitrogen $ per pound Total Phosphorus $ per pound Actual Customers $18.72 per year Equivalent Meters $9.93 per year The 2010 rates included a 0.90% surcharge to recover the DNR NR101 effluent fees. Wastewater volumes, CBOD loadings, suspended solids loadings, total Kjeldahl nitrogen (TKN) loadings and total phosphorus loadings are determined each quarter for each community. These determinations are based on a minimum of seven consecutive days of monitoring data for the current quarter and previous quarter s discharge data for each community. Meter equivalencies are based on the capacities of the different sizes of water meters used throughout the District. A 5/8-inch water meter has a capacity of twenty gallons per minute and is defined as one equivalent meter. The capacities of larger water meters are divided by the twenty-gallon per minute capacity of a 5/8-inch water meter to determine their meter equivalencies. An actual customer is defined as one water meter without regard to size. The numbers of equivalent meters and actual customers in each municipality are set by counting the number of each size of water meter in service in each municipality where water meters are used. In municipalities where water meters are not used, the number of each size water meter that would be required is estimated. In 2010, the average annual residential service charge in the District was about $245. This amount includes $133 for services provided by the District and $112 for services provided by the municipality (e.g. the City of Madison). A survey of 165 of the nation s largest municipalities indicated that the typical residential service charges in the District in 2010 were 65% of the national average of $376. Operating costs per million gallons of treated wastewater for the years 2006 through 2010 were as shown in the table below. Several accounting policy changes in 2008 affect comparisons with prior years. First, benefit costs that had previously all been charged as an administration or treatment expense were charged to all cost centers. The effect of this change is to reduce administration costs and increase collection labor costs. Second, some planning costs are no longer charged to the collection and treatment cost centers, but are included under administration 34

36 costs. The effect of this change is to increase administration costs and reduce collection and treatment costs. The combined effect of the accounting policy changes is to show an overall decrease in the 2007 operating costs of 0.7%. To enable a same basis comparison, column 2007(2) shows 2007 costs using the same accounting policies as were used for 2008 and succeeding years. These changes would increase the 2007 administration costs by 3%, and decrease the collection costs by 9% and treatment costs by 1%. In comparison with the 2008 costs, 2009 overall operating costs increased 3.7% with administration costs increased 12.9%, collection costs increased 0.3%, treatment costs increased 1.9%, and debt service costs increased 3.4%. The large percent increase in administration costs was associated with recognizing liability for other post-employment benefits (OPEB); this is the first year that these costs are reflected in operating expenses. The cost per million gallons increased by 12.9% compared to the 2008 because of the moderate increase in costs combined with a large volume decrease of 8.1%. In comparison with the 2009 costs, 2010 overall operating costs increased 4.0% with administration costs increased 5.8%, collection costs decreased 6.5%, treatment costs increased 5.1%, and debt service costs increased 4.8%. The relatively high increase in administration cost was associated with additional demolition costs. The large percentage decrease in collection costs was due to lower labor and repair service costs. The cost per million gallons increased by 9.9% compared to 2009 because of the moderate increase in costs combined with a significant volume decrease of 5.4%. Costs per Million Gallons of Wastewater Treated District Function (2) Administration $170 $202 $209 $165 $203 $227 Collection Treatment Debt Service TOTAL $1,269 $1,322 $1,314 $1,235 $1,394 $1,532 TRAINING ACTIVITIES During 2010, District employees completed over 5491 hours of training. As a whole, District employees averaged over 65 hours of training per employee during the year. Notable training during 2010 include: Vendor training conducted for Pump Stations 6 & 8, and new Blower engine controller. District employees averaged over 14 hours of safety training each during Safety training is held monthly throughout the year. The District continued phase two of the Manager Supervisor Training Program for the new and prospective Managers and Supervisors. A total of 25 people signed up for the second phase of the training which started early in Training sessions for the program are a mix between courses taught by District staff and courses taught by Madison Area Technical College instructors. The program has been very well received and is a model training program for which other agencies have requested information. 35

37 2010 Average Training Hours by Workgroup Training Hours per Employee Average of 65 hours per employee Workgroups PUBLIC EDUCATION MMSD 2010 Tour Summary In 2010, 53 tours took place with a total of 1741 total participants. Compared to 2009, 34 tours took place with a total of 1008 total participants. Helping with our public education efforts by serving as tour guides were: Paul Nehm, Roy Swanke, Steve Reusser, Jim Post, Jon Schellpfeffer, Ralph Erickson, Matt Allen, Ryszard Zolnik, Dave Taylor, Mike Northouse, and Jeff Brochtrup. Terry Gent and others in the Building and Grounds crew assisted tour efforts by setting up the Multipurpose Room for tours and by keeping the facility Park Like and Parlor Clean. Monty Baker and others in the Lab helped by setting up the Lab display and exhibits. For nearly every tour, Jeff Steven hosted the tour area in the Effluent Building displaying the many species of fish found in streams receiving the District s plant effluent. To highlight the quality of the effluent produced at the Nine Springs Wastewater Treatment Plant, the 50-gallon, flow-through aquariums showcased in the Effluent Building public education room. In addition to the fish tank, this display area includes maps, drawings and pictures of all water, aquatic macroinvertebrate and fish surveys. The tank that houses fish contains species that are commonly collected along Badfish Creek, Badger Mill Creek and the Sugar River. Effluent flows through the aquarium prior to being pumped to Badfish Creek and Badger Mill Creek. Survival, growth rates, and activity of the fish, which are living in 100% effluent, continued to be normal. The 36

38 display area is a favorite attraction of the many tour groups that routinely visit the Nine Springs Plant. It also acts as a canary in a mine shaft scenario to show if the effluent is acutely toxic to some of the biological inhabitants prior to the effluent s discharge to the receiving streams. Tour participants also receive a pencil as a reminder that we need everyone s help in doing the right thing when using water. Tour groups are asked to keep inorganic wastes, chemicals, mercury, and unused medicines out of the wastewater stream to help protect the environment, reinforcing the concept that a toilet is not a waste basket. Time is spent during each tour encouraging people to consider higher education and apprenticeships working towards careers in environmental fields. Interceptor and Fact Sheet News Letters In 2010 two Interceptor newsletters and one Fact Sheet were produced. The Interceptor is a newsletter that is distributed to District employees and sent to our customer communities, regulators, consultants, vendors, retirees, sister agencies and colleagues. The Interceptor keeps everyone updated about activities here at the District. The Fact Sheet newsletter is an internal publication that helps keep the District s employees up to date on issues that affect them. Many people help produce these newsletters, Roy Swanke is the main editor and producer of the Fact Sheet. Jon Schellpfeffer and Matt Allen are the main editors of the Interceptor newsletter. The Interceptor is put together by a 3 rd party graphic artist. In addition, many District employees contribute articles to the newsletters. MMSD Radio Advertising Campaign for Public Education in 2010 During spring time 2010, as part of a five initiative action plan to help reduce inflow (clean water) into the MMSD collection system, the District, for the second year, produced and aired public education radio commercials. The commercials targeted homeowners by encouraging them to check their gutter and downspout systems to make sure the systems would direct water away from their foundations and keep the rainwater from getting into their basements. The radio spot also included information about proper basement sump pump connections and a focus, new in 2010, on conserving water. Complementing the advertising, the District dedicated a webpage to inflow reduction resources in an effort to help educate customers how to prevent rainwater from getting into the sanitary sewer system. To view the webpage and listen to the commercials log on to: PROFESSIONAL PARTICIPATION DURING 2010 The Commissioners of the District support and encourage participation by District employees in activities that promote the knowledge and enhance the image of the water quality field.

LITIGATION On September 17, 2009, the District filed a suit in Dane County Circuit Court against Giles Engineering Associates, Inc. and GLS Utility, LLC and their respective insurance companies to recover costs associated with the repair of the Pump Station 6 force main, damaged by Giles in January Giles subsequently filed a counterclaim against the District related to the incident that they later withdrew. The District received a total of $125,000 from Giles Engineering Associates, Inc. and GLS Utility, LLC on November 16, 2010 and the court subsequently ordered the case dismissed on December 14, On December 3, 2010, Contract Dewatering Services, Inc. filed a suit in Dane County Circuit Court naming Morgan Contracting, Inc. and the District as co-defendants. Contract Dewatering Services alleged that Morgan Contracting failed to pay for dewatering services related to the District s Northeast Interceptor Pumping Station 10 to Lien Road Project. Contract Dewatering Services also alleged that the District was withholding $232,289.98, the amount of the claim, from payment to Morgan Contracting. District counsel responded to the claim on December 17, At yearend, the District still retained the $232,289.98, in addition to the normal contract retainage amount, from payment to Morgan Contracting awaiting direction from legal counsel. Upon payment of the claim amount to Melli Trust in February 2011, the court dismissed the 39

41 District from the case as a defendant and referred the case to mediation/arbitration to be settled between Morgan Contracting and Contract Dewatering Services. At midyear the District was notified by the Department of Natural Resources Air Quality Division that an operating permit was required for the operation of its engines and boilers that use digester gas at the Nine Springs Wastewater Treatment Plant. Based on the size of the engines and the amount of fuel being used in them, a construction permit should have been obtained at the time that the engines were installed in The District has retained Linda Bochert of Michael Best & Friedrich, LLP to represent the District in future negotiations with DNR related to the air quality permits and any potential penalties. Please see the Wastewater Treatment section of this Annual Report for further details related to the air quality permit. STRATEGIC PLANNING INITIATIVES The District conducts a thorough review of its strategic plan and planning process as part of a five-year strategic planning cycle. The latest of these reviews occurred in As necessary, minor plan and process adjustments may be adopted on an annual basis in between the formal review cycles. For each year, focus area action plans are developed and implemented based upon the key challenges and objectives identified within the strategic plan and the organizational priorities for the present year. The directors and the organization adopted seven focus areas during 2010, the third year in the implementation phase of the District s five-year strategic planning cycle. The focus areas were selected based upon the District s four key challenges and their supporting objectives identified during the 2007 strategic planning review. The District s four key challenges are providing great customer service, providing exceptional performance, maintaining a strong financial position, and developing a sustainable workforce. (Further details of the key challenges and their supporting objectives may be found in the third edition of the District s Vision, Goals, and Strategies document.) Each of the seven focus areas helps address an objective or objectives related to one or more of the District s key challenges. Highlighted below are the seven focus areas for 2010 with a brief discussion of related progress during the year: 1. Eleventh Addition. The Eleventh Addition design began in 2010 following completion of the Solids Handling Facilities Planning process. At year end, the design was between 50 and 75 percent completed. Value engineering services were provided by CH2M Hill at the 50 percent completion level. Further details on the Eleventh Addition are included under the Engineering and Construction section of this Annual Report. 2. Master Planning and Follow-up. The District and its consultants completed the District s 50-year Master Plan in A key recommendation in the Master Plan was that the District evaluate effluent reuse options during future facilities planning efforts. The District is currently working with the City of Fitchburg and the University of Wisconsin-Madison to evaluate the potential use of effluent for groundwater recharge. Further details regarding this effort are included under the Research section of this annual report. 3. Phosphorous Management. The Wisconsin Department of Natural Resources undertook several initiatives related to phosphorus that could impact District operations. The Natural Resources Board adopted administrative rule revisions related to phosphorus in June In a separate effort, the 40

42 Wisconsin Department of Natural Resources (WDNR) has issued a draft Total Maximum Daily Load (TMDL) for phosphorus and total suspended solids for the Rock River Basin. These two initiatives could significantly impact the District. The District may be required to make improvements that reduce the level of phosphorous in its effluent and/or assist in funding non-point source practices that provide a similar benefit (trading). WDNR also formed a workgroup to assist in developing a statewide framework to support water quality trading. District staff has been involved in this effort. The District, in cooperation with Dane County, formed a workgroup to help evaluate opportunities for trading at the local level. A more detailed discussion of the above initiatives can be found in the Watershed Projects section of this annual report. 4. Personal and Organizational Learning and Growth. During 2010, the District undertook a number of activities related to personal and organizational learning and growth. Leaders Forums, periodic training sessions for the District s managerial and supervisory employees, were conducted throughout the year and culminated in a document titled Leadership Expectations that identified expected values, skills, and attributes for District leaders. The District conducted an organizational assessment as a follow-up to the first assessment conducted in The Human Resources Group administered the assessment, surveying employees and giving them an opportunity to rate District management and provide feedback. For the second year in a row, District supervisors conducted employee performance reviews for the non-represented employees using the new forms and process developed during 2008 by the Performance Review Workgroup. Phase 2 of the Supervisory and Management Training Program continued throughout 2010 nearing completion by yearend. The Supervisory and Management Training Program was originally developed for all District supervisors and managers, most of whom participated during the programs initial phase. This second phase includes newer supervisors and other future leaders of the District. 5. Asset Management. At the end of 2010, District staff had made little substantial progress to complete a Plant Asset Management Plan; however, the update of Collection System Facilities Plan was roughly 80% completed. A draft of the Collection System Facilities Plan is anticipated to be completed in the March 2011 timeframe with a mid-year project completion. At this time, completion of an initial Plant Asset Management Plan is anticipated later in Workforce/Succession Planning. Workforce and succession planning are ongoing processes that have been a standard part of the directors annual planning. Due to the demographics of the District s workforce, the rate of employee retirements has increased and will most likely continue at higher rates for the foreseeable future. During action plan implementation, the directors developed some new tools, including essential functions worksheets to assist with knowledge capture, employee training, and transition planning, that they integrated into the District s routine planning and management processes. Although this area is unlikely to be a focus area for 2011, the directors will continue to closely monitor workforce demographics, trends, and pending retirements. 41

43 7. Develop Organizational Performance Measures. The directors proposed this focus area with the intent to develop organizational benchmarks or measures that are more formal. The priority of this focus area was considered subordinate to the other focus areas and therefore, it received little attention in At this time, the directors are uncertain whether this initiative will be pursued any further. ENGINEERING AND CONSTRUCTION IN 2010 Solids Handling Facilities Plan/11 th Addition Following completion of the 10 th Addition, a series of operational difficulties was encountered with the Nine Springs Treatment Plant digestion facilities. These included foaming in the thermophilic digesters (especially during winter months), heat exchange problems (due to grease and rag build-up within heat exchangers), and struvite formation in pumps and piping. To alleviate these problems, the District embarked on a Solids Handling Facilities Plan in The primary objective of the Solids Handling Facilities Plan was to review available solids handling process alternatives and provide a detailed recommendation of facilities necessary to assure a reliable, sustainable process for producing Class A biosolids. The team of Applied Technologies and Carollo Engineers was retained to complete the Solids Handling Facilities Planning work. The Solids Handling Facilities Plan was completed in 2010 and was formally approved by the WDNR. Detailed design of the Solids Handling Facilities Plan recommendations began in Since the scope of the work was extensive, it was decided to name the project the 11 th Addition. At the end of 2010, the Preliminary Design Report for the project was complete, and contained numerous technical memos regarding improvements included in the 11 th Addition. Final detailed design was also in-progress at the end of 2010, and was approximately 50% complete. Detailed design will continue through the first half of 2011, with construction anticipated to last from 2011 to The estimated construction cost for the project is $36 million. Collection System Facilities Plan The 2002 Collection System Facilities Plan continued to guide MMSD s implementation of significant collection system improvements during The 2002 Collection System Facilities Plan provides an assessment of the condition and hydraulic capacity of MMSD s collection system facilities, including 95 miles of gravity interceptors, 43.8 miles of wastewater and effluent forcemains, and 17 regional pumping stations. The 2002 Facilities Plan provided a timetable for recommended collection system projects through The estimated total cost for the recommended projects through 2020 was approximately $84 million. As of year-end 2010, the following projects discussed in the Facilities Plan had been completed or were in progress during the previous three years: Pump Stations 13 &14 Firm Capacity Improvements completed Lower Badger Mill Creek Interceptor : Phase 2 Construction completed West Interceptor Extension Replacement completed Pumping Stations 6 & 8 Rehabilitation in progress 42

44 Northeast Interceptor Truax Area Liner completed West Int. Campus Relief Phases V+ - postponed Far East Interceptor Gaston Road Extension completed Northeast Interceptor - PS10 to Lien Road Relief/Replacement in progress South Interceptor Baird Street Extension Liner completed Far East Interceptor Cottage Grove Extension Liner completed West Interceptor MH to MH Liner in progress The original 5-year planning period detailed in the 2002 Collection System Facilities Plan was reached in 2007 and an effort to update the Plan was started in The Capital Area Regional Planning Commission (CARPC) was retained to complete population and flow projections in 2030 and This work was completed in early Throughout 2009 and 2010, MMSD staff incorporated the CARPC capacity evaluation with collection system risk and condition assessments, with a goal to update the Collection System Facilities Plan. This is anticipated to be complete in 2011 and will be used to guide the District s collection system capital improvement program in future years. Pumping Stations 6 & 8 Rehabilitation The 2002 Collection Systems Facilities Plan identified Pumping Stations 6 & 8 as needing improvements to upgrade the overall reliability of the stations and to increase pumping capacity. The rehabilitation of Pumping Stations 6 and 8 includes improvements to pumping equipment, electrical systems and structural components. The project also includes additions to both buildings, new HVAC equipment, and improvements to the exterior of the stations. Design work was completed in 2008 and bids for construction were opened on June 27, Contracts were awarded on June 30, 2008, to the respective low bidders for the three prime contracts as follows: General Construction Joe Daniels Construction Co., Inc. $1,058, Mechanical Construction J.F. Ahern Company, Inc. $2,661, Electrical Construction Forward Electric, Inc. $1,956, Construction of the project started in the fall of As of December 31, 2010, construction was essentially complete, with only minor punchlist items remaining. The General Construction contract with Joe Daniels Construction was 99.8% complete, the Mechanical Construction contract with J.F. Ahern was 99.9% complete, and the Electrical Construction contract with Forward Electric was 99.9% complete. Work is expected to be finished in early 2011 and all projects are expected to be closed-out by the middle of

45 Northeast Interceptor-PS10 to Lien Road Relief/Replacement The 2002 Collection System Facilities Plan identified the existing 48-inch Northeast Interceptor from Pumping Station No. 10 to Lien Road as lacking adequate capacity for peak flows. The interceptor also had significant infiltration in several locations and had suffered concrete deterioration above the normal waterline. To address these issues, the District began preparations to relieve or replace the interceptor. Planning for this work began in 2008 and continued into Detailed design was completed in June of 2009, and included approximately 9,200 lineal feet of new interceptor pipe. Of this, approximately 5,200 feet (from Nakoosa Trail to PS10) was a relief sewer and 4,000 feet (from Lien Road to Nakoosa Trail) was a replacement sewer. Where replaced, the existing reinforced concrete interceptor was abandoned and a new 63-inch corrosion resistant fiberglass pipe was installed. Where relieved, the existing reinforced concrete interceptor remains in service and a parallel 54-inch pipe was installed. Bids for construction were opened on August 27, The Commissioners awarded the contract to Morgan Contracting, Inc., on August 31, 2009, at their respective low bid price of $7,493, Construction began in October of 2009, and as of the end of 2010 the project was essentially complete. Remaining punchlist items and final restoration work will be completed in the spring of Far East Interceptor-Cottage Grove Extension Liner Routine televising of the Far East Interceptor-Cottage Grove Extension revealed deterioration in the top half of the pipe. This interceptor, which was originally installed in 1982, includes approximately 5,500 feet of 18-inch pipe, with portions installed on pilings. Since this sewer is located in a very low/wet area and on pilings, replacement would be difficult and expensive. Because of this, it was decided to line the sewer, which would eliminate the need for excavation and prevent any further deterioration of the pipeline. Planning and design were completed by MMSD staff in 2009 and the project was bid on August 26, The Commissioners awarded the contract to Insituform Technologies USA, Inc., on August 31, 2009, at their low bid price of $304, Construction was completed in early 2010 and the contract with Insituform Technologies USA was accepted by the Commissioners on July 12, The final contract amount, including all change orders, was $303, Badfish Creek Farm Bridge Replacements During 2009, inspection of four farm bridges that cross the Badfish Creek revealed significant deterioration of the structures that support the bridges. Per the original easements for the Badfish Creek Effluent Diversion, MMSD is responsible for maintenance of the bridges in perpetuity. Many of the wooden piers that support the bridges were found to be rotted and erosion around the abutments was observed. Also, current farming practices are much different than when the bridges were constructed in 1958, and the bridges could be overloaded with larger modern agricultural equipment. The center bridge piers also tend to catch floating debris in the creek, which obstructs flow and contributes to bank erosion. 44

46 Planning and design for replacement of the bridges were completed in early 2010 and the project was bid on May 6, The Commissioners awarded the contract to Ruzic Construction Co. on May 10, 2010, at their low bid price of $540, Construction was completed in the summer of 2010 and the contract with Ruzic Construction Co. was accepted by the Commissioners on November 15, The final contract amount, including all change orders, was $526, West Interceptor MH05 to MH Liner This segment of the West Interceptor is located along the west shore of Lake Mendota, in the Marshall Park area. Routine televising of the cast iron interceptor, which was originally constructed in 1931, revealed corrosion and tuberculation above the normal water surface. Due to its close proximity to the shoreline and the potential of significant inflow of lake water if the interceptor failed, it was decided to line the interceptor. Planning and design were completed by MMSD staff in 2010 and the project was bid on October 19, The Commissioners awarded the contract to Terra Engineering & Construction Corp. on October 27, 2010, at their low bid price of $182, As of the end of 2010, construction had not started. This was due to the desire to complete the project during cold weather months, which limits disruption to resident s landscaping and allows the work to be completed during the non-recreational season. Construction is expected to begin in January of 2011 and be completed by April. Process Control System Upgrade The process control system, which is the computer network that controls plant operations, was originally installed as part of the 9th Addition in Although still fully functional, much of the system is obsolete and requires upgrades to both software and hardware (computers, etc.) In 2009, the District embarked on a long-range plan to evaluate the process control system and replace components as required. This included a facility planning phase, where overall needs were to be evaluated along with potential system vendors. Following completion of the facility plan, detailed design would be completed, followed by construction/implementation of the new control system. CDM was retained to perform the facility planning for replacement of the process control system. This work will be completed in early 2011 and design will follow during the majority of Construction is anticipated in 2012 and beyond. Crosstown Forcemain Relocation-High Speed Rail Station During 2010, the Wisconsin Department of Transportation notified the District that the area north of the Monona Terrace Convention Center had been chosen as the preferred location for a highspeed rail station. Numerous utilities were located in this proposed footprint of the rail station, including the District s Crosstown Forcemain. Initial planning to relocate approximately 1,500 lineal of the Crosstown Forcemain outside of the rail station was started in A contingency of $500,000 had been budgeted for the work. In November of 2010, planning for the relocation was discontinued when Governor Walker was elected and the high-speed rail project was formally ended. 45

47 CLEAN WATER FUND LOANS In 1989 the State of Wisconsin replaced the Wisconsin Fund Grant Program with the Clean Water Fund Loan Program. The Clean Water Fund is a state revolving loan fund that was capitalized initially with grants from the U.S. Environmental Protection Agency and by bonds issued by the State of Wisconsin. The District has issued general obligation bonds and notes to the State of Wisconsin for 15 loans under this program. The total amount financed through these Clean Water Fund loans is $113.0 million. The District had three Clean Water Funds loans in 2010 for which the final disbursement had not been received by the end of The status of those loans is as follows: West Interceptor Extension Replacement The District issued General Obligation Sewerage System Promissory Notes, Series 2007A, on December 12, 2007, to the State of Wisconsin Clean Water Fund (CWF Project ). These bonds are for an aggregate amount not to exceed $2,826,309 and are to be repaid at an annualized interest rate of 2.555%. The first interest payment on the loan was made on May 1, The first principal payment was made on May 1, The final bond payment will be made on May 1, The final disbursement for this loan was made on September 22, 2010 bringing the total for this loan to $2,622, Pumping W Stations No. 6 and 8 Rehabilitation The District issued General Obligation Sewerage System Promissory Notes, Series 2008A, on November 12, 2008, to the State of Wisconsin Clean Water Fund (CWF Project ). These bonds are for an aggregate amount not to exceed $9,143,490 and are to be repaid at an annualized interest rate of 2.368%. The first interest payment on the loan was made on May 1, The first principal payment will be made on May 1, The final bond payment will be made on May 1, As of December 31, 2010 the District had received $8,086, from the Clean Water Fund for this project. Northeast Interceptor PS 10 to Lien Road Relief/Replacement The District issued General Obligation Sewerage System Promissory Notes, Series 2010A, on May 26, 2010 to the State of Wisconsin Clean Water Fund (CWF Project ). These bonds are for an aggregate amount not to exceed $8,964,767 and are to be repaid at an annualized interest rate of 2.369%. The first interest payment on the loan was made on November 1, The first principal payment will be made on May 1, The final bond payment will be made on May 1, As of December 31, 2010 the District had received $8,070, from the Clean Water Fund for this project. 46

48 NINE SPRINGS ENERGY USE PROFILE This table shows an estimate of the total amount of electric and thermal energy used at the Nine Springs Wastewater Treatment Plant and the division between purchased and renewable (primarily self-produced) power. The significant decrease in generated electrical power from 2006 to 2007 was due to problems caused by additional moisture and siloxanes in the digester gas and a related problem with one of the two generator engines. Operations staff removed the second generator from service as a precaution. To correct the problem, the District installed a gas drying system that additionally removes hydrogen sulfide and siloxanes. The District also made subsequent repairs and rebuilds to its gas engines during 2008 to In 2008, power use was greater due to the higher flows that followed the June rainstorm events. Near the end of 2010, the District removed its three gas engines from service pending resolution of the District s air quality permits with the Wisconsin Department of Natural Resources. All of these factors have contributed to the lower percentages of self-produced power that have occurred since

Gerry Sachs Gerry retired from MMSD s engineering staff in July Gerry began his employment with the District in June Gerry was first hired to work for the MMSD as part of the field survey crew for the Northeast Interceptor. Following this work, Gerry moved to the District s former First Street office to assist Wayne Johnson with engineering work. Gerry spent the later part of his 40 years with MMSD reviewing and detailing sewer plans and extensions. During the time he was involved with this work the environment changed from strictly paperwork to all digital work. During the past two years, his work relied heavily on databases, computer-aided design work, and 51

53 geographic information systems. In between snacks, Gerry was always working to improve the processes he used to perform his work. MMSD would like to thank you for 40 years of service. Lynn Szudy Lynn retired from MMSD s Information Services group in July Lynn began his employment with the District in April Lynn s network and database skills were a welcome addition to our experience. In 1995, a new Novell network had been established. MMSD did not have any internet access, and many of the old database structures were well aged and needed replacement. These upgrades occurred over the years Lynn worked here. MMSD would like to thank you for 15 years of service. Carl Wright Carl retired with disability pension from MMSD s electrical maintenance staff in November Carl began his employment with the District in March 1981, as a part time worker. He became full time in September 1981 as an Operator Helper. In 1985, Carl advanced to a Field Operator position. Carl filled many positions during his career from Labor Crew, to Field Operator to Apprentice Electrician. At the time of his retirement, Carl was an Apprentice Electrician II. MMSD would like to thank you for 29 years of service. Dick Klaas Dick retired from MMSD s engineering staff in December Dick began his employment with the District in June Dick worked as a Project Engineer on the 6 th and 7 th Addition to the treatment plant.

56 A 1 Board of Commissioners Madison Metropolitan Sewerage District Madison, Wisconsin Independent Auditor s Report We have audited the accompanying statements of net assets of the Madison Metropolitan Sewerage District as of December 31, 2010 and 2009, and the related statements of revenues, expenses, and changes in net assets, and cash flows for the years then ended. These financial statements are the responsibility of the District s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects the respective financial position of the Madison Metropolitan Sewerage District as of December 31, 2010 and 2009, and the results of its operations and cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America. The management s discussion and analysis on pages 2 through 10, is not a required part of the basic financial statements but is supplementary information required by accounting principles generally accepted in the United States of America. We have applied certain limited procedures, which consisted principally of inquiries of management regarding the methods of measurement and presentation of the required supplementary information. However, we did not audit the information and express no opinion on it. A1 Middleton, Wisconsin March 9, h

57 MADISON METROPOLITAN SEWERAGE DISTRICT MANAGEMENT S DISCUSSION AND ANALYSIS FOR THE YEARS ENDED DECEMBER 31, 2010 AND 2009 The management of the Madison Metropolitan Sewerage District (the District) offers this narrative overview and analysis of the District s financial performance for calendar years 2010 and It should be read in conjunction with the District s financial statements which follow this section. The 2010 and 2009 financial statements have been prepared in accordance with generally accepted accounting principles. Financial Highlights Net assets increased by $0.8 million (0.8 percent) from $104.1 million to $104.9 million in This compares to a $1.6 million (1.6 percent) increase in Operating revenues increased by $0.3 million (1.6 percent) from $22.2 million to $22.5 million in This compares to a $0.7 million (3.3 percent) increase in Operating expenses, excluding depreciation, increased by $0.5 million (3.3 percent) from $15.2 million to $15.7million in This compares to an increase of $0.5 million (3.7 percent) in Overview of Basic Financial Statements The financial statements of the District report information of the District using accounting methods similar to those used by private sector companies. These statements offer short-term and longterm financial information about its activities. The Statement of Net Assets includes all of the District s assets and liabilities and provides information about the nature and amounts of investments in resources (assets) and the obligations to District creditors (liabilities). It also provides the basis for evaluating the capital structure of the District and assessing the liquidity and financial flexibility of the District. All of the District s revenues and expenses are accounted for in the Statement of Revenues, Expenses, and Changes in Net Assets. This statement measures the success of the District s operations over the past year and can be used to determine whether the District has successfully recovered all its costs through its user fees and other charges, profitability, and credit worthiness. The Statement of Cash Flows reports cash receipts, cash payments, and net changes in cash resulting from operations, investing and financing activities and provides answers to such questions as where did cash come from, what was cash used for, and what was the change in the cash balance during the reporting period. 2

58 Net Assets A summary of the District s Statement of Net Assets is presented in Table A-1. Table A-1 Condensed Statement of Net Assets (000's) Current Assets $ 25,387 $ 24,997 $ 22,847 Noncurrent Assets Capital assets, net of accumulated depreciation 145, , ,549 Other assets 7,396 7,368 10,164 Total assets 178, , ,560 Current Liabilities 9,262 8,634 7,792 Noncurrent Liabilities 64,409 61,285 61,242 Total liabilities 73,671 69,919 69,034 Net Assets Invested in capital assets, net of related debt 78,660 78,657 75,440 Restricted 15,545 14,987 14,384 Unrestricted 10,705 10,480 12,703 Total net assets $ 104,910 $ 104,124 $ 102,527 As of December 31, 2010 the District had total assets, less accumulated depreciation, of $178.6 million and total liabilities of $73.7 million, resulting in $104.9 million of net assets. Net assets increased by $0.8 million (0.8 percent) in This compares to a net asset increase of $1.6 million (1.6 percent) in The 2010 increase was due to connection charge revenues of $0.5 million and operating income of $0.3 million. Funds represented by the 2010 increase will be used to finance future interceptor construction and to offset a portion of future operating costs. Capital assets (land, structures, equipment, vehicles, etc.) comprise $145.8 million, or 81.6 percent of total assets at the end of At the end of 2009, capital assets had a value of $141.7 million and represented 81.4 percent of total assets. Capital assets increased $4.1 million in 2010 compared to a $3.1 million increase in Future principal payments on bonds total $67.1 million at the end of 2010 and represent 91 percent of the District s liabilities. At the end of 2009, future principal payments on bonds totaled $62.9 million and represented 90 percent of the District s liabilities. Future principal payments were $4.3 million more than at the end of 2009 due to increased borrowing for capital projects in Future principal payments at the end of 2009 were $0.2 million less than at the end of There was an increase in construction activity funded with bond funds in 2010 compared to The District received a Clean Water Fund loan for construction of the Northeast Interceptor Pump Station 10 to Lien Road Relief/Replacement project in The portion of this project constructed in 2009 was initially funded from reserves since the State of Wisconsin was delayed in processing a Clean Water Fund loan for this project in

59 The District s restricted assets consist of reserves for the payment of debt service and for unexpected expenses for the repair and replacement of equipment. Restricted assets increased by $0.6 million in 2010 to satisfy bond ordinance requirements related to the use of service charge revenues for payment of debt service expenses. This compares to an identical $0.6 million increase in Unrestricted assets at the end of 2010 were $0.2 million more than at the end of Unrestricted assets had decreased by $2.2 million in The 2009 reduction was due primarily to the use of reserve funds to finance the Northeast Interceptor Pump Station 10 to Lien Road Relief/Replacement project. Revenues, Expenses, and Changes in Net Assets The District s revenues, expenses, and changes in net assets are summarized in Table A-2. Table A-2 Condensed Statement of Revenues, Expenses, and Changes in Net Assets (000's) Operating Revenues $ 22,535 $ 22,170 $ 21,453 Nonoperating Revenues Total revenues 22,979 22,826 22,235 Depreciation Expense 5,150 5,142 5,174 Other Operating Expense 15,743 15,235 14,692 Nonoperating Expense 1,797 1,754 1,813 Total expense 22,690 22,131 21,679 Income Before Capital Contributions Capital Contributions Increase in net assets 785 1,599 1,053 Beginning Net Assets 104, , ,473 Ending Net Assets $ 104,910 $ 104,125 $ 102,526 Operating revenue for 2010 increased by $0.37 million, or 1.6 percent, from $22.2 million to $22.5 million. This compares to the 2009 operating revenue increase of $0.7 million, or 3.3 percent. The 2010 increase was due primarily to higher service charge rates. Non-operating revenues for 2010 were $0.21 million (32 percent) lower than in 2009, reflecting decreases in interest earned on investments. Non-operating revenues for 2009 were 16 percent lower than in 2008, which was also the result of lower interest earnings. Depreciation expense in 2010 of $5.1 million was 0.16 percent more than the 2009 depreciation 4

60 expenses. The 2009 depreciation expense of $5.1 million was 0.6 percent less than the 2008 depreciation expenses. Other operating expenses for 2010 of $15.7 million were $0.5 million (3.3 percent) higher than 2009 expenses of $15.2 million. Other operating expenses for 2009 were 3.7 percent higher than 2008 expenses of $14.7 million. The higher level of other operating expenses in 2010 was due to increased expenses for miscellaneous (higher construction demolition expenses) electric power, replacement parts and services, and contracted services costs. Higher costs in these areas were offset by lower costs for salaries and benefits, natural gas, and chemicals. Non-operating expenses for 2010 of $1.8 million, which are comprised of interest on the District s outstanding debt and disposal of equipment, were essentially the same as the 2009 nonoperating expenses. Non-operating expenses in 2009 were $0.06 million less than in Capital contributions include contributed capital assets and interceptor and treatment plant connection charge revenues. The one-time connection charges are assessed against each property in the District at the time sewerage service is made available. The charges are made on an area basis. An interceptor connection charge rate has been established for each major District interceptor sewer. The interceptor connection charge rates are adjusted annually to account for changes in construction costs. The Engineering News Record s Construction Cost Index is used for this purpose. Interceptor connection charge rates for 2010 were increased by 3.3 percent. This compares to the 2009 increase of 4.2 percent. The treatment plant connection charge rate is adjusted annually to account for the change in excess capacity debt service paid by current users for facilities at the treatment plant that will be utilized by new users. The treatment plant connection charge rate is further adjusted by the typical bank passbook savings rate, or 4 percent, whichever is higher. The treatment plant connection charge rate for 2010 increased by 5.9 percent. The 2009 increase was 6.1 percent. Increases in 2010 reflect the additions to accumulated excess capacity debt service costs associated with the Ninth Addition, Tenth Addition, and Badger Mill Creek Effluent Return projects. Capital contributions in 2010 of $0.5 million were $0.4 million less than 2009 capital contributions of $0.9 million. This was a decrease of 45 percent compared to Interceptor connection charge revenue was the same for both 2010 and 2009 at $0.5 million, reflecting the continued downturn in the housing market. There were no contributions in aid of construction in Capital contributions in 2009 included $0.4 million of contributions in aid of construction associated with the West Interceptor Relief on the UW Campus. Capital contributions in 2009 had increased 82 percent from the 2008 amount, from $0.5 million to $0.9 million. 5

61 Comparison of Actual Financial Results to Budget Each year the District adopts an annual operating budget and a 10-year capital improvement budget following a public hearing. A comparison of the 2010 budgeted and actual amounts of operating revenues and expenses is shown in Table A-3. Table A-3 Comparison of Operating Budget to Actual Results for 2010 (000's) Budget Actual Variance Revenues From operations $ 22,820 $ 22,535 $ (285) Nonoperating (23) Total revenues 23,287 22,979 (308) Operating Expenses Depreciation expense 5,150 5,150 Other operating expenses: Salaries with benefits 7,677 7,360 (317) Administrative (14) Legal and accounting Insurance (16) Power 3,009 2,979 (30) Natural gas (59) Chemicals (41) Motor and LP fuel Water and sewer services Contracted services 1,736 1,690 (46) Engineering Consulting Communication services (2) Replacement parts and services 1,014 1, Supplies Miscellaneous Total other operating expenses 15,401 15, Total operating expenses 15,401 20,893 5,492 Nonoperating Expenses Disposal of Equipment Interest expense 1,777 1,680 (97) Total expenses 17,178 22,690 5,512 Income before capital contributions $ 6,109 $ 289 $ (5,820) 6

62 The District does not include depreciation as an operating expense in its annual budget, rather, it budgets sufficient income to cover the subsequent year s debt principal payments. For calendar year 2010, operating revenues of $22.5 million were $0.3 million less than budgeted due to slightly lower than anticipated wastewater loadings. Non-operating revenues of $0.44 million for interest income, rent, and other miscellaneous items were $0.02 million (4.9 percent) less than budgeted due to lower than budgeted interest earned on investments. Operating expenses for 2010, excluding depreciation, were $0.3 million more than budgeted. The most significant under budget item was salaries and benefits costs that were $0.3 million less than budgeted. The most significant over-budget items were equipment repair and replacement and miscellaneous costs which were a combined $0.8 million more than budgeted. The miscellaneous costs were $0.4 million more than budgeted because of unbudgeted demolition expenses. Non-operating expenses, which include the net value of retired equipment and the interest costs on the District s outstanding debt, were on budget. Interest costs were $0.1 million less than budgeted. No expenses were budgeted for retiring equipment, and $0.1 million expenses were incurred for retiring equipment in Budgeted income for 2010 of $6.1 million includes $5.9 million for future principal payments on the District s outstanding debt and $0.04 million to fund a portion of the current year s capital improvements. It is the District s policy to finance capital improvements for new users through borrowing. Sewerage system improvements typically have useful lives of more than twenty years, and the District typically issues twenty-year bonds and notes. The system s users pay for the costs of the facilities they require for the conveyance and treatment of their wastewater over the life of the bonds and notes. For this reason, the District does not budget to recover depreciation costs in addition to the debt service expenses, since this would in effect result in double-billing current users for these facilities. Charges to recover debt service expenses reflect the cost of the facilities currently in use. Charges to recover depreciation expenses would reflect the cost of replacing these same facilities at the end of their useful lives. 7

63 Capital Assets At the end of 2010, the District had $146 million invested in capital assets comprised of the Nine Springs Wastewater Treatment Plant, seventeen major pumping stations, over one hundred miles of interceptor sewers and force mains, and associated facilities. Table A-4 summarizes these assets. Table A-4 Capital Assets (000's) Assets Land $ 7,401 $ 7,401 $ 7,401 Structures and improvements 143, , ,995 Mechanical equipment 86,022 80,810 77,723 Office furniture and equipment 4,094 3,998 4,085 Vehicles 2,269 2,204 2,249 Construction In progress 2,752 9,571 5,430 Total 246, , ,883 Less accumulated depreciation 100,635 96,078 91,335 Net property and equipment $ 145,798 $ 141,680 $ 138,548 The District s 10-year capital improvement plan includes $100 million of treatment plant upgrades and expansions and $105 million of collection system improvements. Treatment plant projects and larger collection system projects are expected to be financed with Clean Water Fund loans administered by the State of Wisconsin. Smaller collection system projects will be financed with reserve funds. Reserve fund balances vary depending on construction scheduling, collection of connection charges, and interest earned on investments. A minimum reserve balance of $3 million is maintained to finance any unplanned capital improvement that might be necessary on an emergency basis. One treatment plant project and three conveyance system projects were completed in The total cost of these projects increased the value of the District s assets by $15.9 million. The projects were the Far East Interceptor Cottage Grove Extension Liner ($0.3 million), Northeast Interceptor- Pumping Station 10 to Lien Road Relief/Replacement ($8.4 million), Pump Stations 6 and 8 ($6.6 million), and the Badfish Creek Farm Bridges ($0.6 million). The $8.7 million increase in total assets to $246 million reflects the cost of equipment additions at the Nine Springs Wastewater Treatment Plant ($0.3 million) and improvements in the conveyance system ($8.4 million). 8

64 Debt Administration The District maintains cash and investments in a sinking fund in an amount no less than what is required to meet the balance of the current year s debt service requirements plus the subsequent year s first principal and interest payments in order to abate levying an ad valorem tax for the general obligation debt service. Since the services of the District are not directly related to the value of property, and since a substantial amount of property within the District is exempt from paying property taxes, a tax levy would result in an inequitable cost recovery system. District debt service costs are allocated to used capacity and excess capacity in the facilities constructed with proceeds from the debt being retired. Excess capacity is defined as the difference between the design capacity and the used capacity of each project and is determined annually. Used capacity debt service is recovered based on the volume and pollutant loadings of the users. Excess capacity debt service is allocated in equal amounts to all users through an actual customer rate. This rate in turn is used as one component of the connection charge rate that is applied to newly served areas at the time they are served by extensions to the sewer system. General obligation debt outstanding as of the end of 2010 was $67.1 million which represents the remaining balance on the Clean Water Fund loans from the State of Wisconsin. This compares to a 2009 year-end balance of $62.9 million and a 2008 year-end balance of $63.1 million. Interest on these loans is payable semi-annually at rates of 2.4 to 3.9 percent. Detailed information on the District s Clean Water Fund loans is included in the notes to the financial statements. The District s outstanding debt is expected to increase by $120 million over the ten year period from 2011 to 2020 due to projects in the conveyance system and at the treatment plant. Included in the $120 million is $55 million of debt due to borrowing for the next major treatment plant addition that would address advanced treatment for additional phosphorus removal. A total of $100 million in borrowing is anticipated in 2020 and 2021 due to the treatment plant addition to address additional phosphorous removal. The District s long-range financial plan has taken this future borrowing into consideration. The annual amount of revenue collected to pay future debt service obligations will increase 4.8 percent per year over the next seven years. This will produce adequate revenue while maintaining stable annual service charges through The future $100 million treatment plant expansion would then require a 25 percent rate increase. Once the requirements for such an expansion are better defined, the District s financial plan will be modified to spread this increase over a number of years to lessen the impact on the ratepayers. By statute, the District can borrow up to 5 percent of the equalized value of the taxable property within the District. At the end of 2010 the borrowing limit was $1.78 billion. At the end of 2009 and 2008 that borrowing limit was $1.83 billion. The total amount of debt is expected to be no more than 7 percent of this limit over the next ten years. At the end of 2010 the District s debt of $67.1 million was at 3.8 percent of this limit. At the end of 2009 the District s debt of $62.9 million was at 3.4 percent of this limit. During the last two years the District did not experience any negative changes in debt credit rating or debt limitation. Economic Factors Growth in the District s service area had been relatively constant at a rate of 1.5 to 2 percent per year until the current economic slowdown. In the last five years, growth has slowed. The future growth trend is projected to return to the 1 to 2 percent level during the next decade. Due to increasing costs for meeting infrastructure replacement and capacity needs, the District s charges to a typical residential user are expected to increase at a rate about 1 to 2 percent greater than the rate of inflation over the next decade. This annual increase is somewhat higher than the trend of the past thirty years, which matched the rate of inflation. The District s customer base consists of residential users and similar types of commercial and 9

65 industrial users that, for the most part, do not utilize large quantities of water. This customer base characteristic results in a very stable revenue base since the loss of any one user will not significantly impact the District s service charge revenues. The University of Wisconsin is the largest user of District services and provided 6.0 percent of service charge revenues in 2010 and 6.1 percent in Oscar Mayer Foods Corporation is the largest industrial user and provided 2.7 percent of service charge revenues in 2010 and 2.8 percent in Contacting the District This discussion and analysis is intended to provide information for our customers and creditors concerning the District s financial performance and to demonstrate the District s accountability for the money it receives.

71 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 1 - NATURE OF ACTIVITIES, REPORTING ENTITY, AND SIGNIFICANT ACCOUNTING POLICIES Nature of Activities and Reporting Entity: The District is a corporate body with the powers of a municipal corporation for the purpose of carrying out the collection, transmission and treatment of wastewater. It was created by judgment of the County Court for Dane County entered on February 8, The District, which serves the City of Madison and surrounding cities, villages and towns in the Greater Madison Metropolitan Area, covering approximately 170 square miles, is a special-purpose government that is governed by a five-member Board of Commissioners. The District is accountable to the County of Dane, Wisconsin. However, accountability extends only to the appointment of the District's Commissioners, who are appointed by the County Executive of the County of Dane, Wisconsin. Because the County Executive appoints the commissioners, the District and the County of Dane are considered related organizations. The District is legally separate and fiscally independent of the County of Dane as well as any other state or local governments. It has unlimited taxing powers and has the right to set rates or charges for services provided without the approval of another government. Also, there are no other agencies or entities which are financially accountable to the Commissioners of the District, or whose relationship with the District would require their financial statements to be included within the financial statements of the District. A summary of significant accounting policies follows: Basis of Accounting: The accounting policies of the District conform to generally accepted accounting principles as applicable to local government enterprise funds. The accounts of the District are maintained, and the accompanying financial statements have been prepared, on the accrual basis of accounting. Under the accrual basis of accounting, revenues are recognized when earned, expenses are recognized when incurred, depreciation of assets is recognized, and all assets and liabilities associated with the operation of the District are included in the Statements of Net Assets. The principal operating revenues of the District are charges for service. Operating expenses for the District include costs directly related to administration, collection and treatment of wastewater, and depreciation on capital assets. All revenues and expenses not meeting this definition are reported as nonoperating revenues and expenses. The District's policy is to follow all pronouncements issued by the Governmental Accounting Standards Board (GASB). Prior to November 30, 1989, the District applied all pronouncements of the GASB and all business type accounting and financial reporting for state and local governmental entities defined by pronouncements of the Financial Accounting Standards Board, Accounting Principles Board Opinions, and Accounting Research Bulletins of the Committee on Accounting Procedures. Subsequent to November 30, 1989, as provided in GASB Statement No. 20, the District has elected to follow only the GASB pronouncements. 16

72 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 1 - NATURE OF ACTIVITIES, REPORTING ENTITY, AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Cash Equivalents: For purposes of the statement of cash flows, highly liquid investments with a maturity of three months or less when acquired are considered to be cash equivalents. Deposits and Investments: Investments are reported at fair value based on quoted market prices. No amounts are reported at amortized cost. Adjustments necessary to record investments at fair value are recorded in the statements of revenues, expenses and changes in net assets as increases or decreases in investment income. Investments in the Local Government lnvestment Pool and the Wisconsin lnvestment Services Cooperative are reported at fair value based on the unit prices quoted by the funds, representing the fair value of the underlying investments. The District has adopted a formal investment policy and invests in accordance with Wisconsin State Statutes. Under state statute, investments are limited to: Time deposits in any credit union, bank, savings bank, trust company, or savings and loan association which is authorized to transact business in the state if the time deposits mature in not more than 3 years; Bonds or securities of any county, city, drainage district, vocational education district, village, town or school district of the state; Bonds or securities issued or guaranteed by the Federal government; Any security which matures within not more than 7 years, if that security has a rating which is the highest or 2 nd highest rating category assigned by Standard & Poor s corporation, Moody s investors service, or similar rating agency; Securities of an open-end management investment company or investment trust, if the company or trust does not charge a sales load, is registered under the investment company act of 1940, and if the portfolio is limited to bonds and securities issued by the federal government, bonds that are guaranteed as to principal and interest by the federal government; Repurchase agreements that are fully collateralized by bonds or securities of the federal government; The state local government investment pool. Inventories: Inventories of supplies are valued at cost under the specific identification method. The consumption method is used to account for inventories. Under the consumption method, inventories are recorded as expenses at the time they are consumed. 17

73 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 1 - NATURE OF ACTIVITIES, REPORTING ENTITY, AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Receivables: Receivables are reported at their gross values and are considered to be fully collectible as they are primarily due from other municipalities, except for pretreatment. Receivables related to pretreatment have been reduced by an allowance for the estimated uncollectible amounts of $5,000 and $9,619 as of December 31, 2010 and 2009, respectively, and is included in other receivables. Interceptor Connection Charges: Receivables from interceptor connection charges are recognized when assessed and the revenue is deferred until the property owner connects with the intercepting sewer. No value has been placed on the future assessments against lands which are not currently served by intercepting sewers that were built with capacity to serve those lands. Restricted Cash and Investments: Cash and investments are restricted for the purpose of unexpected repair and replacement and repayment of debt obligations. Capital Assets: Capital assets are defined as assets with an initial cost of $5,000 or greater with an estimated useful life greater than one year. Capital assets are stated at cost. The costs of normal maintenance and repairs that do not add to the value of the asset or materially extend the life of the asset are not capitalized. Major outlays for capital assets and improvements are capitalized as projects are constructed. Interest incurred during the construction phase of capital assets is included as part of the capitalized value of the assets constructed. Depreciation of structures, improvements, mechanical equipment, office furniture and equipment, and vehicles is computed using the straight-line method over the following estimated useful lives of the assets: Structures and improvements Heavy mechanical equipment Light mechanical equipment Office furniture and equipment Vehicles years years years 5-20 years 7 years When capital assets are disposed, depreciation is removed from the respective accounts and the resulting gain or loss, if any, is recorded in nonoperating activities. 18

74 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 1 - NATURE OF ACTIVITIES, REPORTING ENTITY, AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Compensated Absences: District employees earn sick leave of fourteen days per year which may be accumulated up to a maximum of 200 days. Each December employees may elect to receive cash payments for 60 percent of their sick leave accumulated in excess of 100 days and 80 percent for sick leave accumulated in excess of 150 days, paid at their current rate of pay. Each December, employees are paid for all sick leave accumulated in excess of 200 days at their current rate of pay. Upon an employee's retirement or disability, 90 percent (100 percent for employees who have accrued at least 150 days of sick leave at any time during their employment) of previously earned but unpaid sick leave is converted to a cash value based on their current rate of pay, and this amount is contributed to the District s Retirement Health Savings Plan (RHSA) in the employee s name. Monies in this account can be used by the employee on a tax-free basis to pay for qualified medical expenses of the employee, their spouse and dependents. Any amounts remaining in the employee s RHSA account at the time of death of the retired or disabled employee may be used by the surviving spouse or eligible dependents on a tax-free basis to pay for qualified medical expenses. If there is no surviving spouse or dependents at the time of the employee s death, the remaining money in the account reverts to the District. No sick leave conversion amounts are paid to employees that terminate employment for reasons other than retirement or disability. The liability associated with accumulated sick pay for current and retired employees is reported as compensated absences liabilities in the statements of net assets. Employees earn vacation in varying amounts based on length of service. Vacation earned is available for use in the following year. Employees may purchase up to five days of additional vacation each year. Vacation, including purchased vacation, may be accumulated to a maximum of 27 days. Upon an employee s retirement or disability, 100 percent of previously earned but unpaid vacation is converted to a cash value based on their current rate of pay, and this amount is contributed to the District s Retirement Health Savings Plan (RHSA) in the employee s name. Employees that terminate their employment for reasons other than retirement or disability are paid for earned vacation resulting from a carry over at their current rate of pay. Vacation earned in the year of termination is paid at varying percentages, depending upon the time of the year termination is effective. The liability associated with accumulated vacation is reported as compensated absences liabilities in the statement of net assets. Employees may also accumulate compensatory time for overtime work. Compensatory time may be carried over at year end, but must be used by March 31. After March 31, represented employees are paid for any unused compensatory time accumulated in the prior year at their current rate of pay. After March 31, non-represented employees unused compensatory time is credited to the employee s base expense account using the employee s current rate of pay, and the accrued salaries liability is reduced accordingly. The liability associated with accumulated compensatory time is reported as accrued salaries liability in the statement of net assets. Long-Term Debt: The District reports long-term debt at face value in the basic financial statements. Any bond premiums or discounts, as well as issuance costs, are capitalized and amortized over the term of the bond using the straight-line method. 19

75 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 1 - NATURE OF ACTIVITIES, REPORTING ENTITY, AND SIGNIFICANT ACCOUNTING POLICIES (Continued) Net Assets: Net assets are classified in three separate categories. The categories, and their general descriptions, are as follows: Invested in capital assets, net of related debt - indicates the District's total investment in capital assets, net of accumulated depreciation and the outstanding debt used to purchase capital assets. Restricted net assets - indicates the portion of the net assets which have been placed under external constraints imposed by creditors (such as through debt covenants) or laws or regulations of other governments or constraints imposed by law through constitutional provisions or enabling legislation. Unrestricted net assets - indicates the portion of the net assets which is available for appropriation and expenditure in future periods. When both restricted and unrestricted resources are available for debt service, it is the District s policy to use restricted resources first, then unrestricted resources. For unexpected repairs, it is the District s policy to use unrestricted resources first and restricted resources only when needed. Capital Contributions: Capital contributions consist of interceptor connection charges and contributed capital assets. Risk Management: The District is exposed to various risks of loss related to torts, theft of, damage to and destruction of assets, errors and omissions, natural disasters, and employee injury. The District retains the risk of loss for damage or destruction of its buildings (except for rental units), sewerage system and other infrastructure. For all other risks, the District carries commercial insurance. Claims have not exceeded coverage in any of the prior three fiscal years. Pollution Remediation Obligations: The District owns land that has been remediated under a Super Fund clean-up project. On-going monitoring and maintenance of the lands is reported as an operating expense. These expenses totaled $31,271 and $9,987 in 2010 and 2009, respectively. Future expenses are expected to range from $20,000 to $60,000 annually. 20

76 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 2 - CASH, CASH EQUIVALENTS AND INVESTMENTS As of December 31, 2010 and 2009, cash, cash equivalents, and investments included the following: Petty cash $ 250 $ 250 Deposits Demand deposits 150,325 49,817 Investments Institutional investment account U.S. Government obligations 1,720, ,947 U.S. Agency obligations 5,161,119 6,273,496 Insured deposit account 92, ,530 Local Government Investment Pool 13,475,425 16,661,882 WISC - cash management 4,713,681 1,001,764 $ 25,313,667 $ 24,529,686 The cash and investments are reported in the statements of net assets as follows: Cash and cash equivalents Unrestricted $ 8,615,931 $ 8,607,283 Restricted 9,860,382 9,360,294 Investments Unrestricted 841, ,738 Restricted 5,996,259 5,928,371 $ 25,313,667 $ 24,529,686 Deposits in banks are insured by the Federal Deposit Insurance Corporation (FDIC) in the amount of $250,000 for interest bearing deposits and unlimited for non-interest bearing deposits per financial institution. In addition, the State of Wisconsin has a State Guarantee Fund, which provides a maximum of $400,000 per financial institution above the amount provided by the FDIC. However, due to the relatively small size of the State Guarantee Fund in relation to the total coverage, total recovery of losses may not be available. 21

77 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 2 - CASH, CASH EQUIVALENTS AND INVESTMENTS (Continued) The carrying amount of the District's deposits totaled $242,927 and $257,347, with bank balances of $371,538 and $314,120 for the years ended December 31, 2010 and 2009, respectively. Of the bank balances, $371,538 and $314,120 was covered by FDIC insurance and collateralized, leaving no amount as uninsured and uncollateralized for the years ended December 31, 2010 and 2009, respectively. The Wisconsin Local Government Investment Pool (LGIP) is part of the State Investment Fund (SIF), and is managed by the State of Wisconsin Investment Board. The SIF is not registered with the Securities and Exchange Commission, but operates under the statutory authority of Wisconsin Statutes Chapter 25. The SIF reports the fair value of its underlying assets annually. Participants in the LGIP have the right to withdraw their funds in total on one day s notice. At December 31, 2010 and 2009, the fair value of the District s share of the LGIP s assets was substantially equal to the amount as reported in these statements. The investments in the Local Government Investment Pool are covered up to $400,000 by the State Guarantee Fund. Certificates of deposit held in the LGIP are covered by FDIC insurance, which applies to the proportionate public unit share of accounts. The investments in the Wisconsin Investment Series Cooperative (WISC) are not insured or collateralized. WISC is managed by RBC Global Asset Management (U.S.) Inc. Investments are restricted to investments permitted under Wisconsin Statutes Fair value is determined daily and is equal to the value of the trust shares. Funds may be withdrawn in whole or in part from Cash Management any time, funds in the Investment Series may be withdrawn after the minimum of fourteen (14) calendar days. At December 31, 2010 and 2009, the District s share of WISC assets was substantially equal to the amounts reported in these financial statements. The District also has investments in U.S. Government and U.S. Government Agency obligations purchased through a private sector securities dealer and held by a third-party custodian. These investments are readily marketable, specifically identifiable and include discount notes and adjustable and fixed rate mortgage backed securities. Investment securities, in general, are exposed to various risks, such as interest rate, credit, and overall market volatility. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the value of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets. 22

78 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 2 - CASH, CASH EQUIVALENTS AND INVESTMENTS (Continued) Interest Rate Risk: Interest rate risk is the risk that changes in interest rates will adversely affect the fair value of an investment. As of December 31, 2010, the District had the following investments and maturities: Maturity in Years Investment Type Fair Value < >10 Local Government Investment Pool ** $ 13,475,425 $ 13,475,425 $ - $ - $ - WISC 4,713,681 4,713, Money market 136, , SBA pools 93, ,952 Government National Mortgage Association 118, , ,676 Federal National Mortgage Association 2,790, ,009 40,378 2,475,370 Federal Home Loan Mortgage Corporation 2,114, ,911 2,065,159 Treasury Bonds 1,720, ,428 1,223, $ 25,163,092 $ 18,822,165 $ 1,498,846 $ 103,924 $ 4,738,157 As of December 31, 2009, the District had the following investments and maturities: Maturity in Years Investment Type Fair Value < >10 Local Government Investment Pool ** $ 16,661,882 $ 16,661,882 $ - $ - $ - WISC 1,001,764 1,001, Money market 253, , SBA pools 96, ,987 Government National Mortgage Association 135, , ,525 Federal National Mortgage Association 3,458, ,569 3,400,059 Federal Home Loan Mortgage Corporation 2,535, ,196 2,474,479 Treasury Bonds 334, , , $ 24,479,619 $ 18,084,806 $ 167,650 $ 138,113 $ 6,089,050 ** Because the LGIP had a weighted average maturity of less than one year as of December 31, it has been presented as an investment with a maturity of less than one year. The District has not developed policies governing the exposure of its investments to interest rate risk. 23

79 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 2 - CASH, CASH EQUIVALENTS AND INVESTMENTS (Continued) Credit Risk: Credit risk is the risk that an issuer or other counterparty to an investment will not fulfill its obligation. The LGIP and the Trust are unrated with regard to the credit quality rating. WISC is rated AAAm by Standard and Poor's. The remaining investments of the District are U.S. Governmental or Agency securities that are explicitly guaranteed, and therefore credit rating is not applicable. The District has not developed policies governing the exposure of its cash deposits and investments to credit risk. Concentration of Credit Risk: Concentration of credit risk is the risk of loss attributable to the magnitude of a government's investment in a single issuer. It is the policy of the District that funds deposited in any one bank or savings and loan association shall not exceed $1,500,000 at any given time. Investments in the LGIP, WISC and U.S. Government or Agency obligations are not limited as to amount. Custodial Credit Risk: For an investment, custodial credit risk is the risk that in the event of the failure of the counterparty, the District will not be able to recover the value of its investments or collateral securities that are in the possession of an outside party. For deposits, custodial credit risk is the risk that in the event of the failure of a depository financial institution, the District will not be able to recover deposits or will not be able to recover collateral securities that are in the possession of an outside party.

Amounts available in the sinking funds on October 1, 2010 and 2009 were sufficient to finance the subsequent year's debt service requirements, and accordingly, the District was not required to place an amount on the tax roll for debt service. Equipment Replacement: As a condition of receiving State of Wisconsin Clean Water Fund (CWF) loans, the District is required to establish an equipment replacement fund for mechanical equipment. To satisfy this requirement, the District has restricted $3 million of its investments and net assets for unexpected equipment replacement. In addition, the District annually budgets for replacement of equipment. According to the CWF equipment replacement percentage schedule option the District must maintain a minimum replacement fund balance of five percent of the original cost of mechanical equipment. For this purpose the District uses the sum of its light mechanical equipment, office furniture and equipment, and vehicles capital assets. The sum of these capital assets for the year ending December 31, 2010 is $39,469,857. The required five percent of this value is $1,973,493. The $3 million of restricted assets exceed the minimum equipment replacement fund value. For the year ending December 31, 2009, the corresponding mechanical equipment total was $36,991,800 and 5% of this amount was $1,849,

83 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 5 - PENSION PLAN Plan Description: The District contributes to the Wisconsin Retirement System (the Plan), a cost sharing, multiple employer defined benefit pension plan administered by the Wisconsin Department of Employee Trust Funds. The Plan provides retirement and disability benefits, annual cost-of-living adjustments, and death benefits to plan members and beneficiaries. State statutes assign authority to establish and amend benefit provisions to the Employee Trust Fund Board. The Plan issues a publicly available report that includes financial statements and required supplementary information for the Plan. That report may be obtained by writing to Wisconsin Retirement System, Department of Employee Trust Funds, P.O. Box 7931, Madison, WI, , or by calling Funding Policy: Employees are required to contribute 6.2 percent and 5.9 percent of their annual covered salary for 2010 and 2009, respectively, and the District is required to contribute at an actuarially determined employer rate, which was 4.8 percent and 4.5 percent of annual covered payroll at December 31, 2010 and 2009, respectively. The contribution requirements of employees and the District are established and may be amended by the Employee Trust Fund Board. The payroll for the District employees covered by the System for the year ended December 31, 2010 was $5,981,724; the District s total payroll was $6,118,567. The total required contribution for the year ended December 31, 2010 was $657,990. The District makes the employees' contributions on their behalf. The District's contributions to the Plan for both the employee and employer portions for the years ended December 31, 2009 and 2008, was $585,368 and $572,642, respectively, equal to the required contributions for each year. Employees who retire at or after age 65 are entitled to receive a retirement benefit. Employees may retire at age 55 and receive actuarially reduced benefits. The factors influencing the benefit are: 1) final average earnings, 2) years of creditable service, and 3) a formula factor. Final average earnings are the average of the employee s three highest years earnings. Employees terminating covered employment before becoming eligible for a retirement benefit may withdraw their contributions and, by doing so, forfeit all rights to any subsequent benefit. For employees beginning participation on or after January 1, 1990 and no longer actively employed on or after April 24, 1998, creditable service in each of five years is required for eligibility for a retirement annuity. Participants employed prior to 1990 and on or after April 24, 1998 are immediately vested. 28

90 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 9 - POST EMPLOYMENT BENEFITS OTHER THAN PENSIONS The Madison Metropolitan Sewerage District participates in a single-employer defined benefit health care plan administered by the District. The plan provides health insurance benefits for eligible retirees and their spouses through the District s group health insurance plan, which covers both active and retired members. Benefit provisions are established through collective bargaining agreements, personnel policy guidelines, or past practice and state that eligible retirees and their spouses receive lifetime healthcare insurance at established contribution rates. The District pays 100% of the premiums of the lowest health insurance carrier for active employees. If an employee has health insurance through a carrier that is not the lowest, he or she is responsible for the difference. Retirees are responsible for 100% of the premiums applicable for their health insurance group. No contribution requirements are established. As of December 31, 2010 and 2009, the District made no contributions to the plan. The District currently funds these costs on a pay-as-you-go basis. In preparing the estimates for 2008, the District used assumptions that resulted in a determination that the annual required contribution of the employer (ARC), net OPEB obligation and actuarial accrued liability were not material, and accordingly no amounts were reported for During 2009, the District reviewed the plan description and related assumptions. An actuarial valuation was obtained in September 2009 using the alternative method as allowed in GASB 45. The valuation was prepared for This valuation established an actuarial accrued liability of $2.9 million. The District s annual other postemployment benefit (OPEB) cost (expense) is calculated based on the ARC, an amount actuarially determined in accordance with parameters of GASB Statement No. 45. The ARC represents a level of funding that, if paid on an ongoing basis, is projected to cover normal cost each year and amortize any unfunded actuarial liabilities (or funding excess) over a period not to exceed thirty years. The remaining amortization period at December 31, 2010 was 28 years. 35

92 MADISON METROPOLITAN SEWERAGE DISTRICT NOTES TO FINANCIAL STATEMENTS December 31, 2010 and 2009 NOTE 9 - POST EMPLOYMENT BENEFITS OTHER THAN PENSIONS (Continued) The funded status of the plan as of December 31, 2010 and 2009, valuation date, is as follows: Actuarial accrued liability (AAL) $ 2,986,245 $ 2,986,245 Actuarial value of plan assets - - Unfunded actuarial accrued liability (UAAL) $ 2,986,245 $ 2,986,245 Funded ratio 0.00% 0.00% Covered payroll (active plan members) $ 6,074,502 $ 5,687,924 UAAL as a percentage of covered payroll 49.16% 52.50% The schedule of funding progress presented as Required Supplementary Information (RSI) following the notes to the financial statements presents multiyear trend information about whether the actuarial value of plan assets are increasing or decreasing due to relative to the actuarial accrued liability for benefits. Actuarial valuations of an ongoing plan involve estimates for the value of reported amounts and assumptions about the probability of occurrence of events far into the future. Examples include assumptions about future employment, mortality, and the healthcare cost trend. Amounts determined regarding the funded status of the plan and annual required contributions of the employer are subject to continual revision as actual results are compared with past expectations and new estimates are made about the future. The schedule of funding progress, presented as required supplementary information following the notes of the financial statements, presents multiyear trend information that shows whether the actuarial value of plan assets is increasing or decreasing over time relative to the actuarial accrued liabilities for benefits. Projections of benefits for financial reporting purposes are based on the substantive plan (the plan as understood by the employer and plan members) and include the types of benefits provided at the time of each valuation and the historical pattern of sharing benefit costs between the employer and plan members to that point. The actuarial methods and assumptions used include techniques that are designed to reduce short-term volatility in actuarial accrued liabilities and the actuarial value of assets, consistent with the long-term perspective of the calculations. In the January 2009 actuarial valuation, the projected unit credit actuarial cost method was used.
