Backflow Prevention

On January 10th 2022 the City of Owen Sound passed a Backflow Prevention By-law. The  by-law’s purpose is to ensure that the city continues to provide safe and high-quality drinking water to our community by decreasing the chance of backflow into our municipal drinking water system.

The City is legally responsible under the Safe Drinking Water Act, Section 19, Standard of Care to exercise due diligence in the operation of its water system. The installation of backflow preventers is a requirement for specific types of buildings under Section 7 of the Ontario Building Code.  Specifically, this bylaw applies to Industrial, Commercial, and Institutional properties in the City.

The City will cover the cost of the building premise isolation backflow preventor on water and fire service under this program. Either the City’s Backflow Coordinator (a licensed plumber) will install the backflow preventer, or, in the case of some larger installations, a plumber retained by the building owner will install the required device and the building owner will be reimbursed the cost. The building owner will be given a list of qualified contractors that can install and or test these backflow preventers.

This by-law won’t impact residential property owners. In residential buildings, there are limited cross connections and lower risks.
