The San Diego County Water Authority is a public utilities agency that delivers wholesale water to 22 retail providers in the San Diego region. Founded in 1944 and based in San Diego, California, it oversees a multi-decade plan to diversify its water sources and invest in major infrastructure while pursuing fiscal and environmental responsibility. By coordinating supply and policy, it supports the region's 3.3 million residents and underpins a regional economy valued at about $262 billion. In early 2026, the Authority announced a long-term water supply agreement with Eastern Municipal Water District. It has also pursued interregional collaboration, including a pilot program to explore interstate water transfers and exchanges with the U.S. Bureau of Reclamation, the Metropolitan Water District of Southern California, and agencies in Nevada and Arizona.
