About Us

The Municipal Water District of Orange County (MWDOC) is a wholesale water supplier and resource planning agency. Our efforts focus on sound planning and appropriate investments in water supply development, water use efficiency, public information, legislative advocacy, water education, and emergency preparedness. MWDOC’s service area covers all of Orange County, with the exception of the cities of Anaheim, Fullerton, and Santa Ana. We serve Orange County through 28 retail water agencies.
Local water supplies meet nearly half of Orange County’s total water demand. To meet the remaining demand, MWDOC purchases imported water – from northern California and the Colorado River – through the Metropolitan Water District of Southern California (Metropolitan). MWDOC delivers this water to its 28 client agencies, which provide retail water services to the public.

MWDOC is governed by a seven-member Board of Directors. Each director is elected by the public to represent a specific portion of Orange County. MWDOC also appoints four representatives to advocate the interests of Orange County on the Metropolitan Board. MWDOC is the third largest Metropolitan member agency and holds key leadership positions on the Board of Directors that oversee policy development, strategy, and implementation.
