Established in 1888, the Pomona Water collects supply approximately 70% from groundwater wells drawn from three groundwater aquifers: Chino Basin, Six Basins, and Spadra Basin. The additional 5% of our water originates from the San Gabriel Mountains where it flows into San Antonio Canyon. The remaining 25% is provided from Metropolitan Water District of Southern California (MWD) and Three Valleys Municipal Water District (TVMWD). Both MWD and TVMWD import surface water from the Colorado River and Northern California.
