Orange County Water District OCWD and Students of the Quarter
We are doing MUCH better than we were a couple years ago for water conservation and usage. Join us to learn about the OCWD and its water conservation efforts.
OCWD manages three of Southern California’s greatest water supplies: the Santa Ana River, the Orange County Groundwater Basin and the Groundwater Replenishment System (GWRS). It ensures a reliable supply of high quality water for more than 2.5 million residents in north and central Orange County, while protecting environmental habitats and natural resources.
The largest river in Southern California, the Santa Ana River begins in the San Bernardino Mountains and flows downstream to Prado Dam and on to the Pacific Ocean. OCWD owns and manages a 6-mile (9.7 kilometers) stretch of the river. River flows are affected by water use upstream and weather fluctuation, making them less reliable than other water supplies.
One of the largest of several coastal basins in Southern California, the Orange County Groundwater Basin contains approximately 500,000 acre-feet (162.9 billion U.S. gallons; 616.7 million cubic meters) of usable storage water and covers 270 square miles (69,930 hectares; 699.3 square kilometers). The underground basin is millions of years old and is 4,000 feet (1.2 kilometers) at its deepest point. Managed properly, the basin is a reliable source of water.
