Our Service Area

The Municipal Water District of Orange County (MWDOC) is a wholesale water supplier and resource planning agency that serves all of Orange County through 28 retail water agencies (with the exception of the cities of Anaheim, Fullerton and Santa Ana). Local water supplies meet more than half of Orange County’s total water demand. To meet the remaining demand, MWDOC purchases imported water- from the Colorado River and from the State Water Project in the north- through the Metropolitan Water District of Southern California, and distributes this water to its 28 member agencies. These agencies, made up of both city water departments and water districts, provide retail water services to the public.

*MWDOC does not serve residential or business customers directly. To report a water emergency such as water main breaks, service leaks, etc., or to change or start a new water service, please contact your retail water provider directly. Contact information for each of these agencies is provided below.

MWDOC is governed by a seven-member Board of Directors. Each director is elected to a four-year term by Orange County voters who reside within one of the seven divisions in the MWDOC service area.
