Drinking water In the Comox Valley Regional District (CVRD) is regularly tested to ensure it meets Canadian drinking water guidelines. To ensure its ongoing quality, the CVRD continues to upgrade the region’s treatment and distribution systems.
What Do We Do To Our Drinking Water?
We add small amounts of chlorine gas to our water to ensure it is suitable to drink. The Ministry of Health requires a level of chlorine in all drinking water between 0.25 and 0.3 parts per million. Each year, the CVRD performs a drinking water analysis to ensure adherence to all Canadian drinking water guidelines. The ideal is to achieve 0.5 mg per litre of free chlorine residual in water samples taken at the ends of each system.
