treated wastewater to the deep waters of the San Francisco Bay. The LAVWMA pipeline has a current capacity of 21.0 MGD. In 1993, Pleasanton, Livermore, and DSRSD estimated that a total capacity of 32.4 MGD, during dry weather, would be necessary for buildout of the General Plans in their respective service areas. LAVWMA is now considering alternatives for additional export. Further, DSRSD is proceeding to plan a 2.5 MGD advanced treatment demonstration project to allow reuse of wastewater within the Valley, thereby increasing disposal capacity for DSRSD and Pleasanton. In 1993, Pleasanton estimated that a total capacity of 11.3 MGD would be needed to accommodate buildout of the General Plan, plus allow for some potential future General Plan changes. Of the 21.0 MGD of the existing LAVWMA facilities, Pleasanton's capacity is 7.5 MGD. Therefore, Pleasanton's request to LAVWMA and DSRSD has been to increase capacity by 3.8 MGD (from 7.5 MGD to 11.3 MGD). Assuming successful negotiation with EBDA, demonstration of the advanced treatment and reuse/export project by DSRSD, and/or other alternatives, Pleasanton's additional wastewater needs will be provided. b. Water The adequacy of Pleasanton's water system depends on the supply of water available and the capacity of storage facilities and distribution systems to deliver water on demand. Water supplies must be capable of meeting maximum day demands; storage must be capable of meeting peak-hour demand in addition to fire flow volumes and an emergency reserve; and the distribution system must be able to provide required flows at adequate pressures throughout the system. Pleasanton's current contract with Zone 7 allows the City to use a maximum of 3,500-acre-feet per year (an average of 3.1 million gallons per day) from groundwater with the remainder to be obtained from Zone 7. Zone 7 has projected that it can supply sufficient water supplies to meet the City's future needs assuming that it receives an average of approximately 75 percent of its contractual allocation from the State Department of Water Resources and that this supply is supplemented with other planned water supply sources. These additional sources include more imported surface water, water transfers, water conservation, water recycling, and enhanced conjunctive use of the groundwater basin. In order to meet future needs, based on buildout of its customers' General Plans, Zone 7 plans to provide additional water supply, treatment conveyance, and storage facilities to increase its system capacity. 5
