New backflow prevention program aims to keep Ottawa’s drinking water clean and safe

Under the new Ottawa bylaw or what municipalities across Ontario are calling the Backflow prevention program, owners will be needing to install backflow device and perform annual backflow testing and maintenance to ensure water the City’s potable water supply is safe from contaminants.
Backflow prevention programs are already mandated across many Ontario municipalities, including Toronto, Hamilton, London, Markham and Waterloo.

Approximately 14,000 commercial, industrial and residential buildings and homes in Ottawa will require an assessment (backflow prevention survey) to determine the level of risk. Severe and moderate risk buildings will be required to install a backflow prevention device.


Tourangeau Mechanical has 20+ years of Backflow Testing experience and currently tests over 700 backflows annually in the Ottawa area. We will work with owners across the Ottawa valley to test and install backflow prevention devices.
