The City’s sanitary sewer system consists of approximately 258 miles of pipe, ranging from 4 to 42 inches in diameter, and 11 pumping stations. The majority of the system discharges to the Dublin San Ramon Services District (DSRSD) Regional Wastewater Treatment Facility (WWTF) located on Johnson Drive. The DSRSD plant has a design capacity of 8.5 million gallons per day (MGD) of dry weather flow allocated to the City of Pleasanton. The Ruby Hills development in the far southeastern part of the city discharges to the Livermore Water Reclamation Plant in accordance with the Interjurisdictional Agreement between the two cities. The City also has an agreement with Alameda County that allows sewage flows from its Castlewood Service Area to be transported through the City’s collection system for treatment at DSRSD. Four City trunk sewer pipelines are tributary to the DSRSD WWTF: the Highland Oaks trunk sewer, which services the northwestern portion of the City; the East Amador Trunk Sewer (EATS, also known as the Cross - Town Interceptor), which services the northeastern and northern portions of the City; Lift Station 6 (LS-6) force main, which conveys flow from the central and eastern portions of the City; and the Lift Station 8 (LS - 8) force main, which conveys flow from the southern portion of the City. The City’s sew er network is shown in Figure 1-1, and serves as the extent of this study. Page 212 of 323
