Deep dive for households

Kamloops drinking water starts as surface water (rivers, lakes, or reservoirs). The named sources on the utility record are South Thompson River, North Thompson River. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.

Water is cleaned at Kamloops Centre for Water Quality before it enters city pipes. Ultrafiltration membrane plant (commissioned 2005) treating South Thompson River water; rated about 160 ML/day; chlorination for distribution residual.

After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. Single central plant feeds citywide distribution and many reservoirs. North Thompson River is an emergency backup source. Rayleigh Waterworks District inside city limits runs a separate North Thompson-sourced system.

One detail that makes Kamloops water feel local: The plant partners with Thompson Rivers University on research/training space inside a working LEED Gold treatment facility, and recovers nearly all intake water as finished drinking water. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
