Zone 7 is the City’s sole potable water supplier. The treated potable water delivered by Zone 7 must comply with the SWRCB Division of Drinking Water (DDW) and the US Environmental Protection Agency (US EPA). Under its current agreement with Zone 7, the City is limited in developing other water supply sources. Zone 7’s water supply has two major components: 1) incoming water supplies available through contracts and water rights each year, and 2) accumulated water supplies in storage derived from previous years. Incoming water supplies typically consist of annually allocated imported surface water supply and local surface water runoff. Accumulated or “banked” water supplies are available in local and non-local storage locations. Imported water from the SWP, which is owned and operated by the California Department of Water Resources (“DWR”), is by far Zone 7’s largest water source, providing over 90 percent of the treated water supplied to its customers on an annual average basis. Zone 7 continues to develop local sources of water to diversify its water supply portfolio. City Groundwater Production. Per the City’s agreement with Zone 7 (who also serves as the Groundwater Sustainability Agency for the Livermore Valley Main Groundwater Basin) for water supply, the City is allowed a groundwater production quota of 3,500 acre-ft/year, which represents approximately 25 percent of the City’s total supply needs. The City owns three groundwater wells to utilize its groundwater production quota. In November 2022, the wells had to be removed from service due to the detection of PFAS. See “Regulatory Requirements” below. As a result, the City is currently purchasing 100 percent of its water from Zone 7 at the wholesale rate. Page 235 of 318
