City of Anaheim Water Utilities delivers 280 PPM 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.
Anaheim's water is supplied by the City of Anaheim Water Utilities. The local supply measures 280 PPM of hardness, classified as "Hard" — well above the 120 PPM threshold that defines hard water.
The utility also uses chlorine/chloramines at roughly 1.8 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 Anaheim homeowners.
Hard — anything over 120 PPM is considered hard water.
Used for disinfection — causes bad taste and dry skin.
Noticeable chlorine taste and hard water spots on glassware.

The second largest city in Orange County in terms of land area, Anaheim is known for being the home of the Disneyland Resort, the Anaheim Convention Center, and two professional sports teams: the Los Angeles Angels of Major League Baseball (MLB) and the Anaheim Ducks of the National Hockey League (NHL).
