The District receives imported water from Metropolitan Water District (MWD) through its member agency, Western Municipal Water District (WMWD). The District is wholly within the boundaries of WMWD and MWD. Because of this arrangement, all parcels receiving service from the District must be annexed into the boundaries of WMWD and MWD.
