Evergreen Water Hardness & Quality Report (2026)

Evergreen's drinking water is managed by the City of Calgary, drawing from the Elbow River at the Glenmore Water Treatment Plant — Calgary's southwest water treatment facility serving the southern and southwestern quadrants. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness in the Evergreen distribution zone is 213.5 mg/L (12.5 gpg) — classified as very hard by Health Canada, on the softer end of the typical Calgary range reflecting the Glenmore plant's southwest distribution corridor.

Evergreen (an upscale master-planned community in southwest Calgary, bordering Fish Creek Provincial Park along the Elbow River escarpment — one of Calgary's most desirable family neighbourhoods, known for its ravine walking paths, proximity to Spruce Meadows equestrian facility, and the Stoney Trail ring road access) receives Elbow River supply treated at the Glenmore plant. The Elbow River's passage through the Rocky Mountain Front Ranges and Kananaskis Country's Devonian and Carboniferous limestone and dolostone produces hard water at the source; the 213.5 mg/L is somewhat softer than the typical Calgary north and northeast supply (Cranston 234.5 mg/L, Saddle Ridge 267 mg/L from batch 16) reflecting either the Glenmore plant's distribution characteristics in this southwest sub-zone or a specific supply blend characteristic.

At 213.5 mg/L, Evergreen homeowners face persistent scale challenges — kettle and showerhead descaling every two to three weeks is typical. Hot water tanks benefit from annual inspection and flushing. Whole-home water softeners are popular throughout Calgary's southwest communities. The City of Calgary provides water quality information at calgary.ca/water. Evergreen's affluent homeowners will find water softener investment a worthwhile quality-of-life improvement.
