Backflow occurs if low pressure happens in the main water supply line. This causes the drinking water to flow in the opposite direction - from homes and businesses back into the municipal drinking water distribution system - which could result in pollution and contaminants entering the drinking water system.
To reduce the risk of backflow, the Township has a backflow prevention by-law that is targeted at existing and new industrial, commercial, multi-residential and institutional properties. Some homes may also be affected by the by-law, specifically related to the installation of an irrigation system.
Backflow prevention devices require yearly testing by a licensed tester. Completed backflow prevention test reports must be submitted to Development Services within 14 days of the date of the test. A backflow prevention device is required for all irrigation systems.
The installation of a backflow prevention device requires a plumbing permit.
