San Antonio Spreading Grounds Conjunctive Use Project EIR

San Antonio Spreading Grounds Conjunctive Use Project EIR

The proposed project is a conjunctive use groundwater management project that will increase the reliability and reduce the cost of water supply within the Six Basins Area by storing surplus imported water in the Six Basins Area aquifer on an opportunistic basis (when water is available). The Six Basins Area refers to the region of the cities of Claremont, La Verne, Pomona and Upland, and surrounding unincorporated areas of Los Angeles and San Bernardino counties overlying six interconnected groundwater basins. These basins are the Canyon, Upper Claremont Heights, Lower Claremont Heights, Pomona, Live Oak and Ganesha Basins. The surplus imported water would be spread into portions of the San Antonio Spreading Grounds ("Spreading Grounds") in the Upper Claremont Heights Basin and extracted through existing groundwater production wells located throughout the Six Basins' area and by a proposed groundwater production well located on the District's Miramar Water Treatment Plant property. The stored water will be recovered by the parties to the adjudication that governs operation of the Basins and in accordance with the rules of that adjudication.
