Export System The Livermore-Amador Valley Water Management Agency - a joint powers agency comprised of the Dublin San Ramon Services District and the Cities of Livermore and Pleasanton - owns and manages the current wastewater export system. The facilities consist of storage/flow equalization reservoirs, a large pumping station, and a pipeline to convey the treated wastewater across the Dublin Grade. 1-580 traverses the wastewater pipeline as it extends westerly to the San Francisco Bay. The wastewater pipeline facilities connect with the East Bay Dischargers Authority's interceptor and outfall system for discharging treated wastewater to the deep San Francisco Bay waters. The existing wastewater-discharge facilities are designed to pump not only the base dry-weather flows of the three member agencies, but also the wet-weather, or rain-dependent flows that enter each of the sewer-collection systems. The export discharge system operated at capacity during the heavy winter of 1996-97 and again in 1997-98. These peak flows required the system to operate at capacity while using all available storage. In November 1998, PIeasanton voters approved Measure U which allows P1easanton to expand its capacity in the Livennore-Amador Valley Water Management Agency system. The expansion project has now been completed, and has a combined wet weather export capacity of 41.3 million gallons per day (mgd). P1easanton, the Dublin-San Ramon Services District, and Livermore plan to share the allocated expansion increment (20.2 mgd) among them, with PIeasanton acquiring an additional 6.9 mgd and thereby increasing its total wastewater wet-weather discharge capacity to 14.4 mgd. Wastewater Summary As existing and approved projects develop, sewage effiuent will increase. PIeasanton has entered into numerous "sewage reservation agreements" that guarantee capacity to various properties/ projects. Most approved, but un-built, commercial/office development utilizes capacity PIeasanton has "reserved" for it out of its original sewage-treatment-pIant and wastewater-discharge capacities. Because PIeasanton has secured both treatment plant and export capacity by agreement with the Dublin-San Ramon Services District and its participation in the Livermore-Amador Valley Water Management Agency Expansion Project, sewage treatment and disposal capacity is not a constraint in the short- or mid-tenn. The City's current treatment and disposal capacities are adequate for growth anticipated to occur between 2005 and 2025. PIeasanton has secured capacity for its continued existing and future wastewater flows. In addition, Pleasanton's capacity in the discharge pipeline will allow growth in dry-weather flows as well as accommodate its wet-weather flows for many future years. Table VI-1 shows 2005 and 2025 sewage discharge totals. WATER PIeasanton is a water retailer, providing water primarily to the City of PIeasanton but also to several adjacent, unincorporated areas (KiIkare Woods, Remen tract, portions of unincorporated Foothill Road, and other isolated service areas).
