What’s in Diamond Bar’s water?
Sitting on hilly terrain where Los Angeles, Orange, and San Bernardino counties nearly meet, Diamond Bar is also served by the Walnut Valley Water District and its imported supply. With little local groundwater to draw on, the city depends on Colorado River and State Water Project water piped in through the Metropolitan Water District. That water is hard and disinfected with chloramine, which shows up as scale on plumbing fixtures, cloudy glassware, and a faint chemical flavor at the tap. Residents in hillside neighborhoods often notice how quickly buildup returns to showerheads and faucets. A PurAgain system removes up to 99% of contaminants, giving Diamond Bar homeowners softer water and longer lasting appliances.
The only way to know exactly what’s in your Diamond Bar water is to test it, and that in-home test is free.
