Whitehorn Water Hardness & Quality Report (2026)

Whitehorn's drinking water is managed by the City of Calgary, drawing from the Bow River at the Bearspaw Water Treatment Plant — Calgary's northwest water treatment facility serving the north and northeast Calgary distribution. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in Whitehorn is 226 mg/L (13.2 gpg) — classified as very hard by Health Canada, consistent with the Bearspaw plant northeast Calgary supply corridor.

Whitehorn (a residential community in northeast Calgary near Memorial Drive NE and 68th Street NE — a mid-size residential neighbourhood of detached homes and duplexes on the northeast Calgary plateau adjacent to Whitehorn LRT station on the northeast CTrain line, the Whitehorn Community Association, and the Memorial Drive NE recreational corridor, a community of diverse East African, South Asian, and established Calgary families in the northeast Calgary residential belt) draws from the Bow River Bearspaw plant supply. The Bow River carries dissolved Devonian carbonate from the Rocky Mountain Front Ranges, producing very hard supply throughout Calgary. At 226 mg/L, Whitehorn is in the standard Bearspaw plant northeast Calgary range.

At 226 mg/L, Whitehorn homeowners face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks benefit from periodic inspection. The City of Calgary provides water quality information at calgary.ca/water. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Whitehorn neighbourhood.
