Backflow Prevention Survey period extension

Survey completion period extended to 120 days

In Peel, backflow prevention surveys must ordinarily be completed within 60 days.

Due to COVID-19, we’ve extended the period for survey completion to 120 days from the time you receive your letter. For an extension on your survey, email Backflow Prevention or call 905-791-7800 ext. 3101.

Cross connections and backflow devices

Backflow is the flow of water from a high to a low-pressure area. It happens when there is a drop in pressure in the water distribution system.

Cross-connections are in every drinking water supply system. Depending on the system’s size, many potential cross-connections may exist. When backflow happens through an unprotected cross-connection, it could threaten the integrity of the water system.

We safeguard Peel’s drinking water by requiring that private plumbing systems with cross-connections also have backflow prevention devices.

We use backflow prevention survey data to determine if prevention devices must be installed.

Backflow prevention devices must still be installed within one year of your survey being completed. Your backflow device must also be tested every year.

Peel’s Backflow Prevention by-law

As the owner of the municipal water supply, the Region is responsible under the Safe Drinking Water Act to safeguard and protect all municipal water system users.

In place since 2017, the Backflow Prevention by-law ensures the protection of our drinking water by stopping the backflow of contaminated water from private plumbing into our municipal drinking water.

The bylaw applies to all industrial, commercial and institutional facilities in Peel, as well as multi-residential homes and single homes over 600 m2.
