Cross connections for testers
As a certified cross-connection tester, you have an important role in ensuring compliance with Calgary’s Water Utility Bylaw.
Whether it’s installing, replacing or repairing cross-connection devices, performing annual tests or submitting the reports, your efforts help protect Calgary’s drinking water system.
As per The City’s Water Utility Bylaw:
- Cross-connection devices must be registered and tested at installation.
- Devices must also be tested at the time the device is cleaned, repaired, or replaced, and at least once per year.
- Devices protecting irrigation systems are only required to be tested when the irrigation system is turned on for the season, if the system isn’t used the device does not need to be tested.
- Failed cross connection devices must be repaired or replaced within 5 business days.

If you fail to renew, or if your qualifications have lapsed, you can no longer test in the city of Calgary and any test reports received will be returned to the owner of the property.
For AWWA Certification typically you will need to take a recertification course if your qualifications lapse.

What if I have moved, or no longer work for the same company?
It is essential that you report any change of company, address or equipment to the Cross- Connection Control Department. To report a change in your information, please submit your request using the Tester Online Service Request.

When will sight tubes be discontinued for use in Calgary?
Cross Connection Control tests performed with Sight Tubes will no longer be accepted by the City starting April 1, 2022. While the national standard does allow for the sight tubes to be used and the tests are accurate and valid, it does not dictate that municipalities or water service providers must follow or allow this practice.
The City of Calgary is making this decision to facilitate the move to a digital repository (Swift Comply) that requires all testing equipment to be registered and have proof of annual calibration. As the steward of high quality drinking water for Calgarians, The City is responsible for the water quality and safety while making accountable for decisions that mitigate risk to the water system.
We believe this decision best supports Calgarians and the Cross Connection Control Program as we move towards a risk based approach in our digital future. Together with the support of our third party partners such as your company and registered testers we will strive to implement an efficient system that will benefit all parties and keep our water system safe. We appreciate your diligence as we move forward.
