Protecting Our Water

What is Cross Connection Control Program?

The City of Calgary adopted the Cross Connection Control Program as part of the National Plumbing Code in early 2012.

The program oversees guidelines for controlling cross connections and ensuring compliance so that Calgary’s drinking water supply is protected from contaminated water. This is done by preventing water that has been used for irrigation within a facility or home from flowing into the drinking water system.

Cross Connection Control Testing

King’s Irrigation is committed to helping protect the City of Calgary’s water supply from contamination and we have a number of Certified Cross Connection Control specialists on our team. Our specialists are certified through the American Water Works Association, Western Canada Section and registered through the City of Calgary.

According to the City of Calgary’s bylaws homes with a cross connection device must be tested annually.

What is a Cross Connection Control Device?

The following are the approved backflow prevention devices for the City of Calgary:

  • Double Check Valve Assembly (DCVA)
  • Pressure Vacuum Breaker Assembly (PVB)
  • Reduced Pressure Principle Backflow Prevention Assembly Device (RP)

As of January 2012 Dual Check Valves on sprinkler systems for backflow prevention are no longer permitted in the City of Calgary because they are untestable.

What is included in the Cross Connection Control Testing Fee?

King’s Irrigation will send out a Cross Connection Control specialist to your site to perform the test and complete and submit the appropriate City of Calgary paperwork within the five (5) days required. This test and appropriate paperwork can usually be completed under an hour, per device.

Why do cross connection control devices need to be tested?

Cross connection control devices have internal seals, springs and moving parts that are subject to fouling, wear and/or fatigue. Due to this normal wear and tear all cross connection control devices must be tested annually to ensure they are functioning properly.
