Update for Rose Valley Water Area on reports of water discolouration earlier this week

Update: Friday, Oct. 9, 2026

Monitoring and testing at Rose Valley Treatment Plant confirms that drinking water meets federal regulations and provincial guidelines.

Discoloration that occurred temporarily, earlier this week, was from low levels of manganese, which have been resolved with maintenance on the permanganate system having been completed.

With the maintenance completed, water should remain clear.

Should any residual discoloration appear, run your tap until clear. If after 20 minutes, the water does not run clear, please, call the City of West Kelowna at 778-797-2246. An alternative source would be available, in the interim, if needed, at the Asquith Road bulk filling station. Bring clean bottles for filling. 

The City of West Kelowna takes water quality seriously and tests water quality at both water treatment plants. If a water quality advisory is required, for any reason, we, as part of our duty to inform, and our commitment to transparency and accountability, and in consultation with Interior Health, will notify residents. We notify customers through email notifications, our website, and the City’s social media channels.

Date of issue: Oct.5, 2026

Residents in the Rose Valley Water Service Area have reported some discolouration in their water. This is due to seasonal changes creating operational challenges combined with a minor mechanical issue in the permanganate feed system. In consultation with Interior Health, water quality continues to meet the required drinking water guidelines, and no advisory is being issued. The discolouration of the water is not a health concern, but a nuisance aesthetic issue.

The City of West Kelowna tests water quality at both water treatment plants daily and will notify residents of any water quality advisories through email notifications, the website, and through the City’s social media channels.

During commissioning of the new Rose Valley Water Treatment Plant, staff continue to make adjustments to manage the seasonal changes in the source water. This is a normal part of the process of optimizing the new system.
