3. Infrastructure <br /> <br /> a. Sewage Disposal <br /> Pleasanton owns, operates, and maintains a wastewater collection system within <br /> its boundaries totalling about 180 miles and consisting of local and trunk sewer <br /> pipes ranging in size from six to 33 inches in diameter. There are six trunk <br /> sewers and seven pump stations in the system in addition to numerous sewer <br /> mains and collectors. <br /> Based on the projected wastewater flow at buildout of the General Plan, <br /> Pleasanton will require extensive improvements to its existing collection system. <br /> These improvements include construction of new sewers, diversion structures, and <br /> modifications to pump stations. These improvements do not include in-tract <br /> sewer or pipelines smaller than ten inches which are assumed to the paid for by <br /> developers of individual projects. An update of the Collection System Master <br /> Plan is scheduled for 1996. <br /> <br /> Treatment Plant. <br /> Under contract, Dublin San Ramon Services District (DSRSD) provides <br /> wastewater treatment services to the City of Pleasanton. The DSRSD <br /> treatment plant, located immediately southeast of 1-680 and Stoneridge <br /> Drive provides primary and secondary treatment. <br /> The existing DSRSD treatment facility is designed to accommodate <br /> 11.5 million gallons per day (MGD) of wastewater. The City of <br /> Pleasanton is presently entitled to 7.1 MGD. In January 1994, DSRSD <br /> completed a treatment plant master plan that provides staged expansion of <br /> treatment facilities to an ultimate capacity of 36 MGD, which would <br /> enable buildout of the Pleasanton Planning Area and other areas within the <br /> DSRSD service area. The DSRSD plant first would be expanded as much <br /> as possible on its present site; then, additional capacity would be provided <br /> at the old Camps Park treatment site. <br /> <br /> Disposal System, <br /> The current disposal system is owned and managed by the Livermore <br /> Amador Valley Water Management Agency (LAVWMA), a joint powers <br /> agency comprised of DSRSD and the Cities of Livermore and Pleasanton. <br /> The facilities consist of reservoirs, a pumping station, and a pipeline to <br /> convey the treated wastewater across Boehmer Summit to the San <br /> Francisco Bay. LAVWMA facilities connect with the East Bay <br /> Dischargers Authority's interceptor and outfall system for discharge of <br /> <br /> 4 <br /> <br /> <br />
