Citadel Water Hardness & Quality Report (2026)

Citadel's drinking water is managed by the City of Calgary, drawing from the Bow River at the Bearspaw Water Treatment Plant — Citadel is a residential neighbourhood in the far northwest quadrant of Calgary near Stoney Trail NW and Symons Valley Parkway, one of Calgary's outer northwest residential communities developed in the 1990s–2000s, a community of detached homes with scenic Nose Hill Park prairie views, the Citadel Passage pathway system, and proximity to the Edgemont–Country Hills–Citadel recreational corridor, a quiet outer residential suburb at the Calgary-foothills interface with the undeveloped Symons Valley north of the community. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in Citadel is 234.5 mg/L (13.7 gpg) — classified as very hard by Health Canada, consistent with the Bearspaw plant outer northwest Calgary distribution.

Citadel draws from the Bow River Bearspaw plant supply serving the outer northwest Calgary distribution. At 234.5 mg/L, Citadel is in the standard Bearspaw plant northwest Calgary range, consistent with Arbour Lake (229 mg/L from batch 36), Bowness (216.5 mg/L from batch 35), and Varsity (249 mg/L from batch 32) northwest Calgary sub-zones. The Bow River carries dissolved Devonian carbonate from the Rocky Mountain Front Ranges.

At 234.5 mg/L, Citadel homeowners face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks benefit from periodic inspection.
