Centennial Water Quality: What You're Dealing With
Centennial and Arapahoe County water is known for high hardness — typically 14–18 grains per gallon. Water source: South Arapahoe Metropolitan District and Aurora Water, sourced from the South Platte River and Homestake water rights.
Centennial receives water from multiple providers depending on neighborhood, including South Arapahoe and Aurora Water. All sources deliver hard water well above the 7 gpg threshold. Chloramine is used for disinfection, leaving a noticeable chemical taste that a whole-house carbon filter eliminates completely.
Common Centennial Water Problems
- Hard municipal water at 14–18 gpg causing heavy scale
- Chloramine disinfection creating chemical taste and odor
- Scale on appliances, water heaters, and faucets
- Reduced effectiveness of soaps and shampoos
- White mineral deposits on dishware and glass shower doors
- Dry skin and hair from high mineral content
