For more than 60 years, Irvine Ranch Water District has provided quality drinking water, sewage collection and pioneering recycled water services to a growing population in central Orange County, California.  Our territory spans 181 square miles and includes all of the city of Irvine, plus parts of Lake Forest, Newport Beach, Tustin, Costa Mesa, and Orange, as well as certain unincorporated areas of Orange County.

IRWD is a California special district established in 1961 as a drinking water provider. Sewage collection was added in 1963, and in 1967 we launched our nationally recognized recycled water program. We value environmental stewardship, and in 1997 began treating urban runoff. Our Natural Treatment System wetland sites now total 26, including the San Joaquin Marsh and Wildlife Sanctuary, home to more than 200 species of migratory birds. The site was recently recognized as a Wetland of Distinction by the International Society of Wetland Scientists.

The District is governed by a five-member Board of Directors elected by the people we serve to ensure we provide safe, reliable, and cost-effective services in an environmentally responsible manner. Under the Board’s leadership, IRWD has diversified its water portfolio, developed new sources of drinking water, and dramatically expanded the use of recycled water — which has significantly reduced dependence on imported drinking water.
