What Makes Dewdney East's Water Unique?
Local geology and source profile
Dewdney East's drinking water is managed by the City of Regina, drawing from Buffalo Pound Lake (a shallow Prairie reservoir created by the Regina Qu'Appelle Valley dam on Buffalo Pound Creek) via the Buffalo Pound Water Treatment Plant — a facility shared by Regina and Moose Jaw that draws from this notoriously hard Prairie lake source. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) standards, though the TDS (1,177 mg/L) substantially exceeds Health Canada's aesthetic objective guideline of 500 mg/L for TDS. Hardness measures 416.5 mg/L (24.3 gpg) — classified as very hard by Health Canada — one of the highest hardness values recorded in any Canadian municipality, with pH 8.5.
Buffalo Pound Lake is a shallow eutrophic Prairie reservoir in the Qu'Appelle Valley draining the Interior Plains of south-central Saskatchewan — a landscape underlain by Cretaceous marine shale (Bearpaw Formation) and Paleogene clay-rich till rich in calcium sulphate (gypsum), sodium sulphate (mirabilite), and calcium carbonate from ancient Prairie lake evaporite deposits. The Qu'Appelle River valley and its tributaries leach these highly soluble evaporite minerals, producing the extraordinary 416.5 mg/L with a TDS of 1,177 mg/L — one of the hardest and highest-TDS municipal water supplies in Canada. The sulphate and bicarbonate content from the Prairie evaporite terrain produces the exceptionally hard, high-TDS Regina water supply.
At 416.5 mg/L, Dewdney East — and all Regina households — face Canada's most extreme domestic hard-water challenges. Scale accumulates on kettle elements and faucet surfaces within days; weekly cleaning is essential. Hot water tanks, dishwasher elements, and showerhead nozzles are subject to severe calcification. A whole-home water softener is a near-essential household appliance for Regina homeowners, and most city residents use reverse osmosis filtration for drinking water. The City of Regina provides water quality information at regina.ca/water and offers hard-water management guidance for residents throughout the city.
Geology & Source: Supplied by the City of Regina from Buffalo Pound Lake via the Buffalo Pound Water Treatment Plant — the Dewdney East Regina distribution zone carries extremely hard Prairie supply at 416.5 mg/L (24.3 gpg), with TDS of 1,177 mg/L — one of the hardest municipal water supplies in Canada.
