Strathmore Water Hardness & Quality Report (2026)

Strathmore's drinking water is managed by the Town of Strathmore, drawing from the Bow River via the Eastern Irrigation District (EID) or a local water treatment facility east of Calgary — Strathmore is a rapidly growing small city in the Municipal District of Wheatland, the main urban service centre on the Bow River plains between Calgary and Drumheller, a community experiencing dramatic population growth from Calgary suburban expansion on the Bow River prairie, with a strong agricultural legacy as the first irrigation colony established by the CPR in the early 1900s on the southern Alberta plains. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 258 mg/L (15.1 gpg) — classified as very hard by Health Canada, consistent with the Bow River east of Calgary through the Southern Alberta foothills.

Strathmore draws from the Bow River in the Wheatland County prairie corridor east of the Calgary foothills, where the river has gathered dissolved minerals from Devonian and Cretaceous carbonate formations across the Bow Valley and the Eastern Slopes. The 258 mg/L is consistent with the high-hardness Bow River supply in the eastern foothills corridor (High River 259 mg/L from batch 27, Brooks 249 mg/L from batch 27 from the same Bow River watershed), producing characteristically very hard supply in small Alberta cities east of Calgary.

At 258 mg/L, Strathmore homeowners face persistent scale challenges — monthly to bimonthly kettle and showerhead descaling is typical. Hot water tanks accumulate scale with shortened operational lifespans. The Town of Strathmore provides water quality information at strathmore.ca. Health Canada lead precautionary guidance applies to pre-1975 properties in the original Strathmore townsite near the CPR irrigation colony heritage sites.
