About the Cross-Connection Control Program

The Cross-Connection Control Program helps protect Halton's drinking water. It requires property owners and tenants of industrial, commercial, institutional and multi-unit residential buildings to install backflow prevention devices and have them tested by an accredited contractor every year.

Backflow prevention devices ensure water flows in only one direction, preventing anything from re-entering the drinking water system after it is delivered to a building. To learn more about the Region's role, please visit the Cross Connection Control Program webpage.

For property owners: find an authorized tester or link properties

You can also use another contractor and have them contact Halton for instructions on what they need to do. Viewing the list of authorized testers does not require a Halton 311 business account.
