Cross Connection Control Program 

A cross connection is the potential or real physical connection between the Town water distribution system and a contamination source.

To protect the Town water supply from contamination in the event of distribution system pressure loss, a backflow prevention device should be installed on a water service. Water pressure loss could be due to a water main break or an unexpected high demand on the water system (fire hydrant use).

If there is an unprotected cross connection, reduced pressure in the water main may allow contaminated water from the soil (irrigation system), from storage, or from other sources to be drawn into the water distribution system.

Backflow prevention devices are required to be installed on the following water services: 

  • Non-residential
  • Multi-family (four or more units)
  • Irrigation systems (including residential systems)

Preventing Cross Connections

We can all do our part to protect our water supply from contamination at home! Don't leave your garden hose connected to weed and feed dispensers or laying in pools of water.

As per the National Plumbing Code and the Town of Cochrane Water Utility Bylaw (04/2013) property owners must do the following to prevent cross connections:

  • Eliminate cross connections
  • Protect what cannot be eliminated with an approved Backflow Prevention Device or Assembly
  • Have the device tested annually by a certified tester
  • Submit test results to the Town of Cochrane

Backflow prevention devices must also be tested following initial installation; when cleaned, repaired or overhauled; and when they are relocated.

The Town is now using FAST, to manage reporting and tracking of devices.  Testers, if you are interested in entering test results digitally please visit FAST Tester to learn more and sign up! Its user friendly and a time saver.  Please note there is an annual fee to use their service. 

To submit reports directly to the Town, please use these forms:
