Service area & board of directors
The Orange County Water District manages, replenishes and protects the Orange County Groundwater Basin—Orange County’s largest source of drinking water. The basin spans more than 300 miles and provides approximately 85 percent of the water supply to more than 2.5 million residents in north and central Orange County. The District’s boundaries are highlighted on the map below, which also illustrates which OCWD director serves a given community.
A 10-member board of directors governs the District and implements policies that foster sound management of the basin, as well as support the advancement of OCWD’s mission to provide an adequate, reliable, high-quality water supply at the lowest reasonable cost in an environmentally responsible manner. Seven board members are elected and three are appointed by Anaheim, Fullerton and Santa Ana city councils. Explore the page and get to know the OCWD directors.
