Upper District is a special district formed by the region’s voters on December 8, 1959 to help sustain adequate water supplies in the rapidly-developing San Gabriel Valley. The District was incorporated shortly there after on January 7, 1960. On March 12, 1963, residents within Upper District’s service area voted to annex to the Metropolitan Water District of Southern California (MWD).
Through MWD’s facilities, supplemental water is brought into the San Gabriel Valley; first from the Colorado River, and also from the State Water Project. Today, Upper District also provides recycled water and facilitates efforts in water stewardship, including conservation and stormwater capture.
