What’s in Rialto’s water?
Tap water in Rialto is drawn from the Rialto-Colton groundwater basin and delivered by the city's water system along with the West Valley Water District, depending on where you live. That basin sits in the heart of the Inland Empire where mountain-fed groundwater runs hard and mineral-rich, and chlorine is added before the water reaches your home. The result at the tap is familiar to most Rialto homeowners, from scale forming on fixtures and inside water heaters to spotted dishes and dry skin. Because groundwater quality can vary well to well across the basin, many families prefer the certainty of point-of-use filtration. A PurAgain system removes up to 99% of contaminants, giving your household consistently clean and better tasting water regardless of the source.
The only way to know exactly what’s in your Rialto water is to test it, and that in-home test is free.

Rialto, in San Bernardino County, is known for some of the hardest water in the state.
