We want to reduce backflow by ensuring more backflow preventers are installed or maintained across the city. This is why we have a backflow prevention bylaw that that affects commercial, industrial, institutional, large multi-residential buildings and irrigation systems.

Backflow happens when water flows towards our water system instead of towards a business or home. This creates the potential for contamination and is of higher concern for commercial, institutional, large residential buildings and irrigation systems.

Installing a backflow preventer (BFP) can stop this problem before it occurs. These devices ensure unwanted substances do not enter the city's clean water supply.
