Rundle Water Hardness & Quality Report (2026)

Rundle's drinking water is managed by the City of Calgary, drawing from the Bow River at the Bearspaw Water Treatment Plant — Rundle is a residential neighbourhood in the northeast quadrant of Calgary at 68th Street NE near Memorial Drive NE, a community of post-war bungalows and newer infill housing in northeast Calgary adjacent to the Franklin LRT station, the East Hills shopping district, and the 52nd Street NE corridor, one of the established inner northeast Calgary residential communities with a diverse East African, South Asian, and established Calgary working-class heritage. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in Rundle is 215 mg/L (12.6 gpg) — classified as very hard by Health Canada, consistent with the Bearspaw plant northeast Calgary distribution.

Rundle draws from the Bow River Bearspaw plant supply serving the northeast Calgary distribution. At 215 mg/L, Rundle is in the standard Bearspaw plant northeast Calgary range (session reference: 197–267 mg/L), consistent with the adjacent Monterey Park (213.5 mg/L from this batch) and Temple (233 mg/L from this batch) northeast Calgary sub-zones. The Bow River carries dissolved Devonian carbonate from the Rocky Mountain Front Ranges, producing very hard supply throughout the Calgary system.

At 215 mg/L, Rundle 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 post-war Rundle neighbourhood.
