The Municipal Water District of Orange County is a wholesale water supplier and resource planning agency that serves all of Orange County (except Anaheim, Fullerton, and Santa Ana) through 28 retail water agencies. We purchase imported water from the Metropolitan Water District of Southern California and distribute it to our client agencies, which provide retail water services to the public.
The Municipal Water District of Orange County works closely with our client agencies, policymakers, stakeholders, businesses and community organizations to build collaborative partnerships. These partnerships enable MWDOC to expand our services and maximize our resources to better serve the region. We are always looking to build new and mutually beneficial partnerships for current or new programs and projects. For information about partnership development please contact Tiffany Baca, Public Affairs Supervisor at or 714-593-5013.
