The Central Valley Water Solution Act authorizes substantial financial and technical assistance for a wide array of water infrastructure projects in California's Central Valley Project region. This legislation aims to bolster water supply reliability, improve water quality, and enhance drought resilience across the State, with the Secretary of the Interior providing this support. Key provisions include significant investments in groundwater banking and recharge facilities for districts like Westland Water, East San Joaquin Valley, Lindsay-Strathmore, Pixley, Shafter-Wasco, and Arvin Edison. The bill also funds the construction of reverse osmosis treatment plants , high-capacity wells, and new reservoirs, such as the Del Puerto Canyon Reservoir, to increase water storage and improve quality. A major focus is on canal infrastructure improvements , allocating hundreds of millions for subsidence correction projects on the Delta-Mendota Canal and San Luis Canal/California Aqueduct to restore conveyance capacity. It also supports the Friant-Kern Canal Phase II Capacity Correction Project and reverse flow pumpback projects for the Delta-Mendota Canal to mitigate drought-related water shortages and enhance operational flexibility. The Act mandates coordination with Indian Tribes, the State, and public agencies for implementation. Most authorized funds are designated as non-reimbursable and not subject to matching or cost-sharing, except for a specific planning study, and all projects must comply with applicable environmental laws.
