Why Denver Homes Need Water Treatment
Local water quality, hardness levels, and supply sources make water treatment a smart investment for Denver Metro-area homeowners.
Denver Water serves the metro area from two mountain collection systems. The southern system produces moderately hard water (121–180 mg/L, or 7–11 GPG) while the northern system is somewhat softer (40–50 mg/L, or 2–3 GPG). Denver Water itself acknowledges that "an initial scale usually takes two to five years to form and continues to build up over time." Water is harder in winter when frozen reservoirs concentrate minerals. Suburbs like Aurora, Lakewood, Arvada, and the southern metro corridor may experience higher hardness depending on their water source. For Denver's famously dry climate, hard water deposits in humidifiers are a particularly common nuisance that a water softener solves.
