BACKFLOW AND CROSS CONNECTION TESTING
Cross connection or backflow testing is a critical part of a building’s infrastructure. With annual testing of these devices a requirement for all commercial properties, coupled with the need for certified testers and equipment, their importance cannot be overstated.In Calgary, some homes and businesses have cross connection devices at their properties. This device prevents water that has been used for washing, heating and cooling from flowing into our drinking water. The City of Calgary oversees annual testing and compliance of these devices in order to protect Calgary’s drinking water supply from contamination.
I have a cross connection testing letter, Now what???
If you received a letter, you need to have your cross connection device tested by a certified tester who is registered with the City of Calgary.

After testing is completed, the tester should submit the report to our office in 30 days. Check with your tester to make sure the report was filed with us and that you have received a copy of the test report.
