Taking Pride in the Past, Preparing for the Future

Since its beginning in 1933, the Orange County Water District 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.
