Hays Caldwell Public Utility Agency Summary CIP for 2016 Primary Objectives of the CIP The primary objectives that require capital projects in the 2016 CIP are: Delivery of interim water to Buda in 2017; and Delivery of Carrizo water to the Sponsors starting in 2023. Project Phasing The overall project is split into primary phases. When complete Phase 1 will produce and deliver 15,000 acre-feet per year of water; Phase 2 will add an additional 20,560 acre-feet per year of water for a total amount of 35,560 acre-feet per year. Attached is the draft infrastructure map for the project. The Phase 2 project has not been included in the CIP as no infrastructure is anticipated to be associated with this phase for several decades. Phase 1 has been split into four sub-phases as follows: Phase 1A Pipeline and pump station interconnecting the Kyle and Buda water systems. The facilities are anticipated to be used in the short-term to provide for interim water sharing and will also eventually serve as the delivery infrastructure of the Carrizo water to Buda. The pipeline will be sized to handle the full anticipated flow to Buda. The pump station will allow for expansion to provide the full contract delivery amount to Buda. Construction for Phase 1A is anticipated to commence in October 2015 and be completed in 2017 in accordance with the attached schedule. Phase 1B Two wells will be drilled and installed for a capacity of 5,488 acre-feet per year. The primary collection line from the well field to the treatment plant will be installed along with the individual collection lines.

The treatment plant will be built it is anticipated to be a sand filter plant with chlorination equipment, high service pumps and clearwell storage. The site will built to provide for a total capacity of 35 MGD (39,000 acre-feet per year), with filter equipment installed in this phase for 5 MGD of capacity. Treated transmission mains from the treatment plant to the Phase 1A infrastructure will be designed and installed. Most of the lines will be sized for their full capacity, except for the line from the treatment plant to Pump Station #1 which will have a capacity of approximately 15,000 acre-feet per year. Pump Station #1 will be designed and constructed it will pump water to the north to connect to the Phase 1A infrastructure and to the southwest to serve Crystal Clear SUD and Green Valley SUD. Phase 1C Two additional wells will be installed along with the collection lines to allow for an additional 5,488 acre-feet per year of supply yielding a total of approximately 11,000 acrefeet per year. Additional treatment equipment will be installed to provide a total capacity of 10 MGD. Phase 1D Two additional wells will be installed along with the collection lines to allow for an additional 4,000 acre-feet per year of supply yielding a total of approximately 15,000 acrefeet per year. Additional treatment equipment will be installed to provide a total capacity of 15 MGD. Projected Water Cost The table below describes the projected delivered water costs (in 2016 $) at the end of each phase.
