Orange County Water District

Orange County Water District (OCWD) takes the limited water supply found in nature and supplements it to provide water for more than 2.5 million people in Orange County, California. Since 1933, when the California State Legislature formed it, OCWD has been entrusted to guard the region's groundwater basin.  OCWD manages and replenishes the basin, ensures water reliability and quality, prevents seawater intrusion, and protects Orange County's rights to Santa Ana River water.

The following cities rely on the groundwater basin, managed by OCWD, to provide 85% of their water demands: Anaheim, Buena Park, Costa Mesa, Cypress, Fountain Valley, Fullerton, Garden Grove, Huntington Beach, Irvine, La Palma, Los Alamitos, Newport Beach, Orange, Placentia, Santa Ana, Seal Beach, Stanton, Tustin, Villa Park, Westminster, and Yorba Linda.
