Orange County Water District

OC GROUNDWATER BASIN (through end of February 2019)
OCWD is one of the few groundwater management agencies able to track the groundwater basin’s “water budget” on a monthly basis. This information allows the District to make more informed management decisions about future water supplies and pumping.

Taking Pride in the Past, Preparing for the Future

Since its beginning in 1933, OCWD has grown far more extensively and rapidly than its founders could possibly have anticipated. Throughout the decades, the District has developed and introduced new technologies to manage water supplies, and is now a world leader in groundwater recharge.
