Where Your Water Comes From
100% of your drinking water travels hundreds of miles to reach your home. Walnut Valley Water District relies on imported water supplies from the Metropolitan Water District of Southern California (MWD) and Three Valleys Municipal Water District (TVMWD). MWD imports water from Northern California via the State Water Project and from the Colorado River via the Colorado River Aqueduct. About 45% of Southern California’s water supply comes from these two sources.
