Backflow prevention testing is mandatory for all commerical and industrial businesses in Saskatoon according to Backflow Prevention Testing bylaw 7567.
A “back-flow prevention device” is installed to prevent liquids or solids from mixing with safe drinking water. If the back-flow prevention device is not present, the drinking water may become contaminated or polluted;
The Meter Shop’s Cross Connection Inspectors conduct on-site inspections when notified of a new back-flow prevention device installation. All inspections include the necessary documentation (including photographs of serial numbers, photos of the devices used, whether the devices have been thoroughly tested, and if appropriate devices have been properly installed). If changes or modifications to the installed backflow prevention system are required, the building owners and/or contractors are notified . If the provided changes are not made in a timely manner (according to the due date), water supply to the property in question may be suspended until the necessary corrections are made. All of the testing and inspection reports (along with photographs and correspondence) are kept on file permanently for each service address.
Once installed, backflow prevention devices must be tested annually by a licensed backflow tester.
