Water softeners for hard water
Very hard water. Whole-house softeners are the high-ticket fit; salt and test kits support the install.

Treatment plants
Bearspaw Water Treatment Plant
Draws from Bearspaw Reservoir on the Bow River; supplies roughly 60% of Calgary’s treated water, primarily serving the north via an interconnected grid.
Glenmore Water Treatment Plant
Draws from Glenmore Reservoir fed by the Elbow River; supplies roughly 40% of the city’s water, primarily serving the south.
How it reaches your street
High-lift pumps send treated water into transmission mains that feed storage reservoirs and pump stations across the city. Bearspaw and Glenmore systems are cross-connected so either plant can support demand citywide. Calgary also sells bulk treated water to regional customers including Airdrie.

Reading this page
Calgary's most recent drinking water sample (2026-07-22) reports hardness of 191 mg/L, classified as very hard, and pH 7.7, drawn from a groundwater water source and treated at Calgary Water Treatment Plant. Lead measured 0.7 μg/L and fluoride 0.6 mg/L.
Free chlorine measured 1.2 mg/L in this sample. No E. coli was detected in this sample.
Calgary's hardness of 191 mg/L is above the Alberta average of 168 mg/L across 19 tracked municipalities, with a provincial average pH of 7.5.
These readings summarize a single compliance snapshot, not a certification of the water reaching your tap. Test your own water periodically, especially on a private well, and consider a softener if hardness is classified hard or very hard.
How to use this page: read the headline metrics first, then where the water comes from (map and tap story), then the parameter table and source footer.
Health parameters meet Health Canada limits; turbidity above the 1 NTU typical target and very hard water.
One or more parameters exceed a Health Canada drinking water guideline or turbidity target.
