What is Backflow Prevention

Protecting Whitby's drinking water supply.

Backflow is the unintended reversal of water flow through a cross-connection, where water that has been used or could be contaminated flows backward into the clean municipal water supply. This can occur when there is a sudden drop in supply pressure, such as during a main break or heavy demand event.

Ontario Regulation 170/03 and Durham Region municipal by-laws require any property with a cross-connection risk to install an approved backflow preventer and have it tested annually by a certified tester. The results must be submitted to the municipality. Mechora handles the full compliance cycle: testing, documentation and submission.

Whitby's commercial zones along Dundas Street and Brock Street, its medical facilities near Lakeridge Health, and its industrial parks all require annual backflow certification. Durham Region enforces cross-connection control requirements and Mechora provides full compliance documentation.
