Sahali Water Hardness & Quality Report (2026)

Sahali's drinking water is managed by the City of Kamloops, drawing from a local reservoir or Thompson River watershed source — Sahali is a residential hillside community on the western bench above central Kamloops in the Thompson-Nicola Regional District of British Columbia's southern Interior, a neighbourhood of single-family homes and townhouses on the Sahali plateau overlooking the confluence of the North and South Thompson Rivers and the downtown Kamloops valley, with sweeping views of the dry bunchgrass hills and ponderosa pine slopes characteristic of the Kamloops semi-arid Interior. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 105 mg/L (6.1 gpg) — classified as moderately hard by Health Canada, consistent with the Kamloops hillside distribution sub-zone supply.

Sahali draws from a local Kamloops reservoir or from the Thompson River at Kamloops Lake — the City of Kamloops supply from the Thompson River system. At 105 mg/L, Sahali's supply is harder than the lower Thompson River corridor benchmark (75.5 mg/L from reference data), reflecting the specific Kamloops hillside distribution sub-zone characteristic. The Thompson River at Kamloops drains the Columbia Mountains and Interior Plateau through Eocene volcanic terrain with some Paleozoic carbonate outcrops, producing moderately hard water that varies by seasonal flow and distribution sub-zone.

At 105 mg/L, Sahali homes experience light to moderate scale deposits — cleaning every two months is advisable. Hot water tanks benefit from periodic inspection. The City of Kamloops provides water quality information at kamloops.ca. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Sahali plateau neighbourhood.
