West Valley Water District (District) is a Special District governed by a five-member Board of Directors providing retail water to approximately 83,218 customers. The District serves drinking water to portions of Rialto, Colton, Fontana, Bloomington, and portions of the unincorporated area of San Bernardino County, and a portion of the city of Jurupa Valley in Riverside County. Our mission is to provide a reliable, safe drinking water supply to meet our customers’ present and future needs at a reasonable cost and to promote water-use efficiency and conservation.

West Valley Water District obtains water from both local and imported sources to serve its customers and routinely tests for contaminants from these sources in accordance with Federal and State Regulations.

The District vigilantly safeguards its water supplies. Staff collects samples on a weekly, monthly, quarterly, annual and triennial basis in accordance with U.S. Environmental Protection Agency and State Water Resources Control Board – Division of Drinking Water (DDW) regulations.
