City of Riverside Public Utilities delivers 375 PPM extremely hard water to your home. Our whole-home filtration systems remove hardness, chlorine, and scale — for softer skin and better-tasting water from every tap.
Riverside's water is supplied by the City of Riverside Public Utilities. The local supply measures 375 PPM of hardness, classified as "Extremely Hard" — well above the 120 PPM threshold that defines hard water.
The utility also uses chlorine/chloramines at roughly 2.3 mg/L for disinfection. While safe to drink, these leave a chemical taste and odor and can dry out skin and hair. The high mineral content causes scale buildup on fixtures, glassware, and appliances — the most common water complaint we hear from Riverside homeowners.
Extremely Hard — anything over 120 PPM is considered hard water.
Used for disinfection — causes bad taste and dry skin.
High mineral content and elevated TDS from imported and local water.
