Cross Connection Control Program

A cross connection is a potential or real physical connection between Cochrane’s water distribution system and a contamination source. Unprotected cross connections may allow contaminated water from the soil, storage, or other sources to be drawn into the distribution system. This occurs when there is reduced pressure in the water main due to a break or unexpected high demand, such as fire hydrant use. 

To protect Cochrane’s water supply, a backflow prevention device should be installed. 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. To prevent cross connections at home, don’t leave your garden hose connected to weed and feed dispensers or laying in pools of water. 

The National Plumbing Code and Cochrane’s Water Utility Bylaw both require that property owners do the following to prevent contamination:

  • 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

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

Submitting reports

Cochrane uses FAST Tester to manage reporting and tracking of backflow prevention devices.  Testers, if you are interested in entering test results digitally, please visit FAST Tester to learn more and sign up. Please note that there is an annual fee to use their service. 

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

Test results can be emailed to Operations at, or dropped off at 124 Griffin Rd.
