Southeast Water Coalition


The Southeast Water Coalition Joint Powers (SEWC) was created in July 1991 and is comprised of eleven cities. These agencies formed a joint power authority to improve and protect the quantity and quality of the regional water supply. SEWC's water purveyors service a population of 670,000 in a service area of 93+ square miles.

The SEWC Board of Directors consists of one representative (normally a Councilmember) from each member city. The Administrative Entity acts as a steering committee consisting of one Public Works type staff member from each member city plus three non-voting (advisory) members from the Central Basin Watermaster, Golden State Water Company, and California Water Service (two private utilities serving several member cities).


SEWC's mission is to prevent the contamination of the Central Groundwater Basin from migrating contaminated groundwater and to encourage good governance of water policies to ensure the availability of reliable, quality, and affordable water.
