The minutes were approved. OPERATIONS & MAINTENANCE UPDATE The Operations Manager presented an update on maintenance and production activity for the month of August 2017; he reviewed charts that represent various activities related to district operations and maintenance including the District s preventative maintenance program. He stated the District experienced a spike in leaks due to increased water usage associated with warmer weather. The Operations Manager stated that water production reports showed a decrease in water usage from July to August; and the District operated using 80% groundwater and 20% surface water, and did not purchase any State Water during the month of August. 1 Minutes 9/25/2017 bvm

3 WATER SYSTEM RELIABILITY The Director of Engineering and Operations stated that in March, the District exceeded its fourth quarter average for TTHM s at Plant 134. The District notified all customers of the violation, and held a public information workshop to address any customer concerns as well as posting weekly water sample information on the District s website. During the six-month period following the exceedance, the District implemented measures that successfully reduced the TTHM levels, and is expected to be within compliance during the next reporting quarter. ADJOURN The meeting adjourned at 3:00 p.m. Ronald L. Coats Governing Board Member Nanette Shelton Governing Board Member 2 Minutes 9/25/2017 bvm

4 To: From: STAFF REPORT ENGINEERING AND OPERATIONS COMMITTEE Operations Manager Agenda Item #2. Meeting Date: November 27, 2017 Discussion Item Subject: Valve Replacement at Plant 56 RECOMMENDATION: This report is provided to the Engineering and Operations Committee for its information only. BACKGROUND / ANALYSIS: The District maintains 15 different storage facilities throughout the service area. A critical component of these sites is the ability to control incoming and outgoing water flows. Recently, production staff identified a damaged 10-inch isolation gate valve in need of replacement at Plant 56. This location is a 500,000 gallon water storage reservoir on Shasta Drive north of the San Manuel Casino. This valve at Plant 56 is critical in allowing water to flow from the Foothill zone into the storage reservoir. Water from the reservoir is sent through booster pumps to the Canal zone. This is an important part of our distribution system because it allows us to supply water at a variety of elevations. The identified valve works in conjunction with another valve to allow operators to adjust an altitude control valve which determines the water level of the reservoir at Plant 56. Due to the damaged gate valve, operators were unable to perform the required maintenance on the important control valve and will not have the ability to adjust the water levels in the reservoir at Plant 56. To replace the damaged gate valve staff identified two options. Option one, we could completely drain the tank and simply replace the 10-inch valve. Draining of the tank is a time-consuming process which requires careful planning to ensure water supply reliability and very specific sampling requirements to allow the tank to be placed back online. Option two, would be to hire a certified SCUBA tank diver to temporarily plug the pipe inside the reservoir which would allow the tank to remain full of water and in service, while our crews safely replace the needed valve. Staff evaluated the two options and determined it would be best to keep the reservoir in service.

15 To: From: STAFF REPORT ENGINEERING AND OPERATIONS COMMITTEE Operations Manager Agenda Item #3. Meeting Date: November 27, 2017 Discussion Item Subject: Operations Report October 2017 RECOMMENDATION: This report is provided to the Engineering and Operations Committee for its information only. BACKGROUND / ANALYSIS: The Operations Department uses a variety of tools and methods to monitor and track all maintenance activities that occur within the department. The attached report provides monthly data for the calendar year. Monitoring these items ensures that the department is on track to achieve the goals and objectives for each year and to develop historical records for important items including water production, water source, and energy usage. By comparing the present year to the prior year average we have a fact based understanding of water usage, conservation efforts, and how efficient energy is used within the District which assists us in developing the next years operating budget. A number of maintenance activities are also tracked and monitored such as leak repair, valve and fire hydrant maintenance, sewer main line cleaning and sewer main line camera. These are important indicators of our reactive versus proactive efforts and are used in the development of capital improvement projects. Most of the activities are routine and preventative maintenance performed every day to ensure that the District s infrastructure is in top shape. Every year maintenance activities are scheduled and the monthly monitoring ensures these goals are met. Leak repair is a reactive activity and usually associated with aging water pipes. Tracking leak repairs provides valuable insight into the areas that are in most need of considering a Capital Improvement Project.
