<br />Housing Constraints City of Pleasanton | C-43 <br />the existing groundwater supply by 30 years. This project would rehabilitate existing well facilities, <br />construct a new well facility, and construct a Centralized Treatment Facility for disinfection and <br />PFAS treatment of groundwater before distribution. The preliminary cost estimate of the project <br />is $46 million. Given project cost and other considerations, in September 2022, the City Council <br />authorized staff to proceed with performing a Water Supply Alternatives Study and put the PFAS <br />and Groundwater Wells Rehabilitation Project on hold. The City is also exploring additional <br />alternatives such as: <br />• Drilling of new City wells with or without PFAS treatment, depending on the location of the <br />wells. This would require test drilling and groundwater sampling; <br />• Zone 7 providing 100 percent of all water supply, both in the near term and in the future; <br />and, <br />• Consideration of purchasing water supply from outside Zone 7. <br />This Housing Element contains Program 4.5 to adequately address water supply concerns to <br />support the development of the City’s sites inventory described in Appendix B (Sites Inventory & <br />Methodology). <br />Sewer <br />The City of Pleasanton owns and maintains the pipelines, manholes, force mains, pump stations, <br />and siphons in the local sewer collection system within the City’s limits. Most of the City’s existing <br />collection system is in satisfactory condition and operates in accordance with acceptable industry <br />standards for conveyance of average dry weather flows, peak hourly dry weather flows, and peak <br />wet weather flows during a generally acceptable storm event. The Pleasanton General Plan <br />adopted in 2009 identified the need for future improvements to the existing local collection and <br />pumping system. These improvements included the construction of new or parallel sewers; <br />diversion structures; and modifications, improvements, or complete reconstruction of various <br />pump stations. The General Plan also provides that maintaining and enhancing the existing local <br />sewer collection system will be funded as part of the City’s Capital Improvement Program (CIP), <br />and new sewer lines will be funded and constructed by new development as it occurs. The City’s <br />sewer capacity is sufficient to serve the housing sites identified in Appendix B (Sites Inventory & <br />Methodology); however, under Program 4.4 the City will ensure future sewer infrastructure <br />remains adequate. <br />Dublin-San Ramon Services District (DSRSD) provides Pleasanton’s sewage treatment services. <br />Disposal of treated effluent from DSRSD’s plant to the San Francisco Bay is provided by means <br />of disposal lines managed by LAVWMA (Livermore Amador Valley Water Management Agency), <br />a Joint Powers Authority (JPA) between the City of Pleasanton, the City of Livermore, and DSRSD. <br />A 2017 capacity evaluation of the DSRSD showed that the DSRSD Wastewater Treatment Plant <br />had spare capacity. Recent recycled water projects and conservation efforts for reuse of <br />wastewater within the Tri-Valley service area have helped to reduce impacts on treatment <br />capacity.
