Eastern Municipal Water District (EMWD) is a public utility based in Perris, California, that provides water and related services to a 682-square-mile service area in Southern California, serving nearly one million people. Its authority is defined by the Municipal Water District Act of 1911 and the California Water Code, and it has been part of the Metropolitan Water District of Southern California since its annexation in 1951. EMWD operates within the broader regional water system and serves both residential and commercial customers within its service area. In 2026, EMWD took part in a notable regional development by entering into a long-term water supply agreement with the San Diego County Water Authority, signaling continued cross-border collaboration for water resources.
