The Resort Municipality of Whistler (RMOW) regularly inspects and cleans its 15 reservoirs to ensure they stay running and do not cause contamination of Whistler’s drinking water.
Three to four of Whistler's reservoirs are inspected and cleaned annually to ensure residents don’t experience unexpected service interruptions or water quality problems.
Whistler’s reservoirs must stay in operation continuously to fulfill fire storage requirements. As a result most of Whistler’s reservoirs require cleaning and inspection using SCUBA divers. Whistler’s newest reservoir was designed with two chambers to eliminate the need for divers and permit work to occur more safely and at any time of the year.
Inspection includes reviews of
- structural integrity
- the condition of equipment, such as fully submerged pipes, ladders, pipes and valves.
Maintenance tasks identified during inspection are scheduled based on the urgency of the issue.
Residents should not experience water quality issues as a result of reservoir cleaning. In the unlikely event a problem was to arise, any potentially affected residents would be notified with specific information and instructions.
Cleaning, inspection and maintenance work are separately identified and tracked in the annual water budget so council and staff can accurately plan for costs in future years.
