Sahali Water Hardness & Quality Report (2026)

The City of Kamloops Water Division supplies the Sahali neighbourhood, part of the Thompson-Nicola Regional District. Their water originates from multiple sources, primarily the South Thompson River and local reservoirs, with groundwater from wells and aquifers also contributing to the supply. Treatment takes place at the McDonald Water Treatment Plant and the Cooney Bay facility. Here, water undergoes filtration, disinfection using chlorination, and fluoridation before reaching the taps of over 100,000 residents.

The Thompson River watershed, which feeds the supply, carves through a landscape marked by Paleozoic limestones and Cretaceous sedimentary rocks belonging to the Kootenay Group. Overlaying these are Quaternary glacial deposits. The presence of carbonate and evaporite-rich formations allows minerals like calcium and magnesium to dissolve into the water, giving it a moderate level of hardness. However, granitic bedrock in the higher elevations contributes softer water components, resulting in a balanced mineral profile influenced by both seasonal runoff and groundwater.

Homeowners might notice a moderate amount of scale building up in appliances like kettles, dishwashers, and water heaters, which can reduce their efficiency and lead to higher energy bills. You may also find that laundry requires a bit more detergent, and glassware sometimes shows spotting after washing. To manage these effects, regularly descaling appliances with vinegar, installing filters that inhibit scale, or even considering a whole-house water softener are practical steps. The water's naturally alkaline pH, typically between 7.5 and 8.2, is due to bicarbonates.
