Chaparral Water Hardness & Quality Report (2026)

Chaparral's drinking water is managed by the City of Calgary, drawing from the Elbow River at the Glenmore Water Treatment Plant — Calgary's southeast water treatment facility. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in Chaparral is 222 mg/L (12.9 gpg) — classified as very hard by Health Canada, consistent with the Glenmore plant south Calgary supply corridor.

Chaparral (a master-planned lakeside community in the extreme south of Calgary, built around the private Chaparral Lake recreation area near Macleod Trail SE and the Tsuut'ina Nation border — one of Calgary's southernmost established communities, with a large man-made lake featuring beaches, water sports, and exclusive community amenities, surrounded by single-family homes and the Fish Creek Provincial Park green corridors in the far south Calgary residential belt) draws from the Elbow River Glenmore plant supply. The 222 mg/L is at the standard Glenmore plant range for the south Calgary corridor, harder than the far outer extremity sub-zones (McKenzie Lake 184.5, Copperfield 193.5 mg/L) but softer than the inner Glenmore distribution (249 mg/L from reference data).

At 222 mg/L, Chaparral homeowners face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks accumulate scale with shortened operational lifespans. The City of Calgary provides water quality information at calgary.ca/water. Health Canada lead precautionary guidance applies, though Chaparral's post-1990 construction features modern plumbing throughout.
