About Us

Our mission is to provide the service area with a reliable supplemental supply of regional and locally developed water in an environmentally and economically responsible manner.

Roughly three quarters of Ventura County residents use water purchased by their retail purveyors from Calleguas’ distribution system. Some purveyors have wells and blend water from Calleguas with groundwater. Others rely exclusively on Calleguas. Calleguas does not deliver water directly to consumers. Most questions about water quality or service changes are best answered by the local retail purveyor.

Calleguas’ primary job is importing and distributing water from Metropolitan Water District of Southern California; water that arrives via the State Water Project from northern California. To increase reliability, Calleguas can also pump water from its Las Posas Well Field.
