Temple Water Hardness & Quality Report (2026)

Temple's drinking water is managed by the City of Calgary, drawing from the Bow River at the Bearspaw Water Treatment Plant — Temple is a residential neighbourhood in the northeast quadrant of Calgary near 68th Street NE and McKnight Boulevard, an inner northeast Calgary community of detached homes and townhouses at the Franklin-McKnight LRT corridor, adjacent to the Temple Lake pathway system and the 52nd Street NE commercial strip, one of the established 1970s–1980s residential communities in the northeast Calgary residential belt with a diverse multicultural community including East African, South Asian, and Filipino-Canadian families. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in Temple is 233 mg/L (13.6 gpg) — classified as very hard by Health Canada, consistent with the Bearspaw plant northeast Calgary supply.

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

At 233 mg/L, Temple 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 Temple neighbourhood.
