Ottawa’s Backflow Prevention Program


Ottawa's Backflow Prevention Program

The City of Ottawa’s Backflow Prevention Program protects drinking water quality by ensuring the appropriate installation and inspection of devices that prevent contaminated water from flowing back into the City’s water distribution system.

Backflow Prevention

Backflow is the unwanted flow of contaminated water reversing into your clean potable water supply system. Backflow is typically caused when there is an abnormal drop in water pressure and contaminated water is siphoned back into your clean water supply. This is typically referred to as back-siphonage and/or back pressure.
