Martindale Water Hardness & Quality Report (2026)

Martindale's drinking water is managed by the City of Calgary, drawing from the Bow River at the Bearspaw Water Treatment Plant — Calgary's north and northwest water treatment facility. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in the Martindale distribution zone is 229 mg/L (13.4 gpg) — classified as very hard by Health Canada, consistent with the Bearspaw plant Calgary distribution corridor.

Martindale (a large residential neighbourhood in northeast Calgary — one of the city's most multicultural communities, home to an enormous South Asian (primarily Punjabi and Gujarati) community in the Martindale–Taradale–Falconridge corridor, with gurdwaras, mandirs, and the vibrant South Asian commercial strip on McKnight Boulevard NE, the community also referred to as the 'Little India' of Calgary NE) draws from the Bow River via the Bearspaw plant. The Bow River drains the Rocky Mountain Front Ranges through Devonian and Carboniferous limestone, dolomite, and shale, producing very hard water at 197–267 mg/L throughout the Calgary distribution network. Martindale's 229 mg/L is at the moderate end of the Bearspaw distribution range.

At 229 mg/L, Martindale homeowners face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks benefit from periodic inspection and flushing. The City of Calgary provides multilingual water quality information at calgary.ca/water, including resources in Punjabi, Hindi, and Gujarati relevant to Martindale's South Asian community. Health Canada lead precautionary guidance applies, though Martindale's predominantly post-1980 construction features modern plumbing throughout.
