Rose Valley Treatment Construction Requires Water Use Changes

Tap water

Press release from the City of West Kelowna on September 3, 2020:

The City of West Kelowna, in consultation with Interior Health, will issue a planned Boil Water Notice for the Lakeview-Rose Valley System, for up to one week, effective Tuesday, September 8, for civil works required for Rose Valley Water Treatment Plant. No outdoor watering will also be required to ensure water availability for other domestic uses.

The important construction milestone involves the tie in of a 600mm main that will eventually connect the Lakeview-Rose Valley System to the water treatment plant. This proactive Boil Water Notice is being issued because the works may result in untreated water entering the system. Without the benefit of chlorine treatment, disinfection against microorganisms (bacteria, protozoa, etc.) will not occur; and therefore, all users must use water brought to a rolling boil for at least one minute or seek a safe, alternative source for brushing teeth, drinking, making baby formula, beverages, food and ice and washing fruits and vegetables.

The bulk filling station at Shannon Lake and Asquith Roads provides a safe, alternative source of drinking water from the state of the art Powers Creek Water Filtration Plant that uses multiple methods of treatment, which the City will replicate at the Rose Valley treatment facility when completed in 2022. Customers can use the touch-free filling station free during the Boil Water Notice. Bring clean bottles for filling. The tap is located on the Asquith Road side of the facility. In keeping with COVID-19 guidelines, users should not touch the station nor their faces, sanitize their hands before and after using the station, and maintain a safe distance of two meters between themselves and others.

The water main tie-in work will also reduce by 40 per cent the amount of water available throughout the Lakeview-Rose Valley System. To ensure that water is available for boiling, cooking, laundry and bathing, no outdoor domestic and agricultural use is required until Saturday, September 12 at 12 p.m.

To ensure essential water availability throughout the system at all times, crews must complete a second similar tie-in to a 750mm water main, anticipated by the end of September. The City will issue more information as the date for that work approaches.

The City also advises Rose Valley Trail users that the trailhead location on Rosewood Drive will be inaccessible on Wednesday, September 9 due to construction traffic and equipment staging. Crews recommend accessing the trails via other points such as Roseridge Court.

We appreciate the patience and understanding of residents and businesses during this required infrastructure work.
