Drinking Water Quality

Following a substantial community effort and many years, Whistler has an updated Official Community Plan and Vision (OCP) that sets the course for the community into the future. Whistler Council adopted the OCP at its meeting June 23, 2020. The new vision and OCP builds on Whistler 2020, Whistler’s previous guiding policy document. Work is underway to align existing community performance indicators with the new vision and OCP. Updated 2019 data will be available in summer 2020.

Drinking Water Quality

Whistler’s drinking water system continues to provide high water quality as the system did not experience any boil water advisories in 2018.

Why monitor this

Access to clean, healthy drinking water is a basic health requirement for people living in or visiting Whistler.

What this measures

This indicator measures the percent of dwelling-days that the RMOW delivered quality drinking water.

This indicator measures quality and reliability of Whistler’s drinking water and delivery system, reporting a score out of 100%. A perfect score of 100% means that for each day of the year quality water was delivered to all of Whistler’s 15,000+ dwellings. An imperfect score of less than 100% means that at some point during the year diminished water quality lead to a boil water advisory that impacted at least one dwelling for a period of time. Scoring scales based on the duration boil water incidents and the number of residential and commercial dwellings impacted. Boil water advisories are issued when tested sample results do not meet Canadian Drinking Water Guidelines and as a precautionary measure when there is some cause for concern, such as a minor break somewhere in the water delivery system.
