The need for a new Water Treatment Plant

The Comox Valley Water System provides drinking water to approximately 45,000 residents in Courtenay, Comox and surrounding areas but it did not meet provincial guidelines, because it relied on only one level of treatment. It led to recurrent boil-water notices, as the one treatment level could not ensure high enough standards during incidents of turbidity.

The new system and treatment plant, opened in September 2021, uses three treatment processes: filtration, UV disinfection and chlorination.

The history of water quality issues in the Comox Valley dates back to before 2005, when Island Health (then VIHA) ordered the CVRD to complete a Watershed Risk Assessment, which identified major risks to the Comox Lake water source. Watching this video will help you to learn more about our watershed and the history of water quality in Comox Lake.

Protecting our drinking water requires two important steps: treating the water, and protecting the source.

The area of land that drains into Comox Lake is approximately 461 square kilometres and the majority is KFN traditional territories or privately owned. Balancing interests such as private ownership, active logging, recreation and hydroelectric power generation, while sustaining critical fish and wildlife habitat, provides challenges for watershed management.

Our Watershed Protection Plan recognizes that high quality drinking water is produced by a healthy ecosystem. This plan outlines and considers watershed protection actions specific to the Comox Lake Watershed. This video explains what we are doing to protect the quality of drinking water by preserving the watershed.
