Cross Connection Control

What is Cross-Connection Control?

Cross connection control is the process of making sure that water used for non-potable purposes (irrigation, industry, chemical dilution, etc.) does not contaminate our potable (drinking) water system. The simplest measure we can all take to reduce the risk involves ensuring an air gap exists between the tap or water outlet and the holding tank. For example, always ensure the garden hose is above the flood rim of the janitor bucket or sink. Remember: Never leave a garden hose submerged.

Bylaw 2005-02 provides more information regarding the regulatory aspects of the program.


1. What steps should I take to protect my drinking water?

Simple steps can ensure you protect your customers and loved ones from drinking contaminated water. For example, install an inexpensive, frost free Hose Bib Vacuum Breaker on all outdoor faucets.

2. Where do I find information on backflow preventers?

Contact the City's Cross Connection Control Coordinator for information. Alternatively, plumbing supply stores and plumbers can also provide information on the products they sell or install.

3. Why do the backflow preventers require annual testing?

In order to ensure our drinking water continues to be protected from back pressure or back siphonage, some backflow preventers must be tested at minimum annually as per CSA B64.

Occasionally, backflow preventers fail and must be either flushed, repaired, or replaced.
