BACKFLOW PREVENTION

To help protect the safety of the City’s drinking water, it is mandatory under the City of Toronto’s Water Supply By-law (opens in new window) for property owners of industrial, commercial, institutional and Part 3 residential properties (as defined by the Ontario Building Code), as well as construction sites, to install a backflow prevention device on the water supply line(s) to their facility. This is done to isolate buildings from the City’s water distribution system, helping to ensure contaminants do not enter drinking water.
