What Makes Lawson's Water Unique?
Local geology and source profile
Lawson (a post-war residential neighbourhood in northwest Saskatoon, near the University Heights and Lawson Heights mall area) receives its drinking water from Saskatoon Water, drawing from the South Saskatchewan River at the Saskatoon Water Treatment Plant and blending with deep Prairie artesian aquifer groundwater. Treatment includes coagulation, sedimentation, lime softening, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) standards. Hardness measures 412 mg/L (24.1 gpg) — classified as extremely very hard by Health Canada, with TDS of 1,160 mg/L, the same extreme supply characteristic of all Saskatoon distribution zones.
Lawson shares the Saskatoon Water city-wide supply — a blend of the moderately hard South Saskatchewan River surface water and deep artesian groundwater from the Mannville Group and Lea Park Formation Cretaceous Prairie strata, where prolonged groundwater contact with gypsum (calcium sulphate), dolomite, and evaporite deposits of the Williston Basin–Saskatchewan Platform produces the extreme hardness and TDS that characterise Saskatoon's uniformly hard water. All Saskatoon neighbourhoods — Lawson, Lakewood, University Heights, Core Neighbourhoods — receive the same blended supply.
At 412 mg/L, Lawson homeowners face extreme scale accumulation on all water-contact surfaces. Whole-home ion-exchange softeners with a brine tank are near-standard equipment in Lawson's established 1950s–1970s residential housing stock. Saskatoon Water provides water quality and treatment guidance at saskatoon.ca/water. Homeowners in Lawson's older housing are also advised to follow Health Canada lead precautionary guidance applicable to the generation of Saskatoon homes built before 1975, when lead plumbing was still in common use.
Geology & Source: Supplied by Saskatoon Water from the South Saskatchewan River blended with deep Prairie artesian aquifer groundwater — Cretaceous Prairie carbonate and evaporite mineral loading produces extremely hard water at 412 mg/L (24.1 gpg).
