Backflow Testing in Calgary

  • Backflow occurs when water flows in the wrong direction through your plumbing system, allowing contaminated or non-potable water to enter the clean water supply. This often happens due to sudden drops in water pressure or back pressure from equipment. Without a certified backflow prevention device, pollutants such as fertilizers, chemicals, or bacteria can enter your drinking water.

  • The City of Calgary requires annual backflow testing and certification for commercial, industrial, and some residential properties. Calgary’s water system serves more than one million people, so preventing backflow is not just about protecting your property. It is about protecting the entire community from water contamination.

    • Commercial buildings: restaurants, offices, retail shops, warehouses

    • Industrial facilities: manufacturing plants, laboratories, mechanical shops

    • Multi-family residential properties: condominiums, apartment complexes

    • Residential homes: properties with irrigation systems, boilers, or fire suppression systems

    If your property has cross-connections where potable water meets equipment such as boilers, irrigation, or chemical mixing systems, Calgary bylaws require installation and annual testing of a backflow prevention device by a certified tester.

    • Bylaw Compliance: Required by the City of Calgary for many properties

    • Health and Safety: Protects your drinking water from pollutants and bacteria
