Backflow Prevention Program
The Municipality of Thames Centre has put in place a Backflow Prevention Program, under By-Law 6-2019, to ensure that the treated water in any watermain, buildings, and homes stays free of any contaminants, pollutants, and un-potable water. The way in which this is done is by installing a backflow prevention device to the water connection to ensure no backflow event occurs.

What is Backflow?
Backflow is the reversal of the normal direction of water from the customer’s premises into the municipal drinking water system. Potential backflow hazards can be caused by fire sprinkler systems, solar heating systems, swimming pools, boilers, or lawn irrigation systems.
