Whole-home softening, filtration, and reverse osmosis drinking water for Walnut homes. Assessment first, equipment sized to your address.
Walnut sits in the Walnut Valley Water District service area, and the district states that 100 percent of its drinking water is imported. It reaches Walnut through Three Valleys Municipal Water District and the Metropolitan Water District, from the Colorado River Aqueduct and the State Water Project. No local groundwater forms part of that supply.
That distinction matters when you are reading about water in the San Gabriel Valley, because Walnut is not drawing from the basins that dominate those stories. What a Walnut home actually contends with is imported hardness. The regional figure for Metropolitan Water District supply is around 11.7 grains per gallon, and Los Angeles County broadly runs between 6 and 18 grains depending on the blend.
