Formed in 1954, San Bernardino Valley Municipal Water District is a regional agency responsible for long-term water supply planning in the San Bernardino Valley. The District imports water through the State Water Project and manages groundwater storage within its service area. Established under the Municipal Water District Act of 1911, San Bernardino Valley has broad authority related to water and related services, but does not provide water directly to retail customers.
We don’t deliver water directly to homes or businesses. Instead, we support 15 water retailers — including cities, utilities, and mutual water companies — who serve neighborhoods across the Valley.

Partnerships expanded with local agencies to tackle high groundwater issues and develop recycled water solutions. The Seven Oaks Dam was approved, reshaping regional flood control and water supply planning.
