Water supply systems are susceptible to contamination if water flows in the reverse direction of piping systems. This is known as backflow and can be prevented with proper cross connection equipment.
To keep Whistler's drinking water standards as high as possible and prevent backflow contamination, the RMOW is implementing a Cross Connection Control (CCC) Program.
Cross Connection Assessments
The RMOW contracted Maintenance Tracking Systems Inc. (MTS) to conduct assessments on the water system connections of industrial, commercial and institutional operators in Whistler from July to October 2014.
MTS assessed the following recommendations for the RMOW:
- Provided users with recommendations on how to improve their cross connection systems;
- Determined if a user’s existing backflow prevention device is in compliance with the British Columbia Plumbing Code; and
- Assign a cross connection hazard classification for the user’s operation.
The RMOW has been working with industrial, commercial and institutional operators classified as high-hazard to address any potential cross connection issues.
Users who have not received or misplaced the cross connection assessment for their operation can contact the RMOW for further information.
The RMOW values the community's cooperation and participation with this program to safeguard our drinking water supply.
Pools and Hottubs
Residential cross connection control types include items such as pools and hot tubs. Residents should be aware that pools and hot tubs that are permanently connected to the home plumbing system are direct cross connections and must be protected with a suitable backflow device. An unprotected cross connection could draw pool water and chemicals back into your household plumbing system and public water supply. When filling a pool or hot tub with a hose, never submerge the end of the hose as this is another cross connection. Always leave an air gap when filling pools, tubs, sinks or containers. Or use a backflow prevention device known as a hose connections vacuum breaker. This can be purchased at your local plumbing supply store.
