North Kamloops Water Hardness & Quality Report (2026)

North Kamloops's drinking water is managed by the City of Kamloops, drawing from a local Thompson River watershed reservoir on the north bank — North Kamloops is the industrial-residential neighbourhood on the north bank of the Thompson River directly across from downtown Kamloops, in the Thompson-Nicola Regional District of the BC Southern Interior, a community of light industry, residential streets, and the North Shore area of the Kamloops urban region, connected to downtown by the Overlander Bridge and the Yellowhead/Trans-Canada Highway interchange at the confluence of the North and South Thompson Rivers. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, fully meeting the Guidelines for Canadian Drinking Water Quality (GCDWQ). Hardness measures 84.5 mg/L (4.9 gpg) — classified as moderately hard by Health Canada, at the lower end of the Kamloops distribution range.

North Kamloops's 84.5 mg/L is softer than the south Kamloops plateau sub-zones (Sahali 105 mg/L and Aberdeen 106 mg/L from batch 31), reflecting the north valley bottom supply routing from the Thompson River watershed. The Thompson River at Kamloops carries water from the North and South Thompson drainage — the Eocene volcanic and Interior Plateau terrain with some Devonian and Paleozoic carbonate outcrops in the Thompson-Nicola region, producing the moderate 84.5 mg/L for the north valley distribution.

At 84.5 mg/L, North Kamloops homes experience light to moderate scale deposits — cleaning every two months is adequate. The City of Kamloops provides water quality information at kamloops.ca. Health Canada lead precautionary guidance applies to pre-1975 properties in the established North Kamloops industrial-residential neighbourhood near the Thompson River north bank.
