Orange County Water District
The Orange County Water District (OCWD) is a groundwater wholesale agency responsible for managing and protecting the Orange County Groundwater Basin. The basin is a vital local resource that provides 85% of the drinking water supply to 19 cities and retail water districts, who serve a collective 2.5 million people in north and central Orange County. Formed in 1933, the District has implemented cutting-edge programs and projects to maximize local water resources, enhance water reliability, ensure high-quality water, prevent seawater intrusion, and protect Orange County’s rights to Santa Ana River water.
