Deep dive for households
Courtenay drinking water starts as surface water (rivers, lakes, or reservoirs). The named source on the utility record is Comox Lake. That is the water that eventually reaches kitchen taps after treatment, not a separate bottled brand.
Water is cleaned at Comox Valley Water Treatment Plant (4701 Lake Trail Road) before it enters city pipes. CVRD plant (2021): coagulation, filtration, UV, sodium hypochlorite. Courtenay operates Class 3 distribution only.
After treatment, water moves through pumps, storage, and underground mains to reach streets and buildings. CVRD supplies bulk treated water to Courtenay, Comox, K'ómoks First Nation, and the Comox Valley Water Local Service Area.
One detail that makes Courtenay water feel local: The $126M Comox Lake plant ended turbidity-related boil-water notices that previously hit the valley when lake turbidity spiked. Lab grades for hardness, lead, and pH sit on the city water quality page; this overview is about the route the water travels.
