SPECIAL FEATURES OF MEMBER AGENCY

The Municipal Water District of Orange County (MWDOC) was formed by Orange County voters in 1951 under the Municipal Water District Act of 1911 to provide imported water to much of Orange County.

MWDOC is a wholesale water agency charged with providing imported water to 27 water districts and cities and two private water companies. In 2001, MWDOC consolidated with Coastal Municipal Water District, which provided wholesale imported water supplies to water agencies and cities serving the coastal areas of Orange County from Newport Beach south to San Clemente.

MWDOC is the second largest member agency of the Metropolitan Water District of Southern California (Met), the agency that supplies Southern California with the majority of its imported water. Imported water comes to Orange County from Northern California and from the Colorado River.

MWDOC's primary responsibility is to ensure that the present and future water needs of its members are met through system and supply reliability. MWDOC represents its members at regional, state and federal levels by advocating for development and protection of water supplies and planning and coordinating the water needs for its service area. The District also maintains an award-winning water use efficiency program and coordinates countywide water/wastewater emergency preparedness and response efforts.

MWDOC serves imported water to about 2.3 million residents.
