Cross connections for multi-unit buildings and businesses

The City is committed to providing safe, reliable drinking water. To protect drinking water from contamination, Water Services runs the Cross Connection Control Program.

Industrial, commercial and institutional customers are required to have a cross-connection control device installed on their incoming water services at the water meter location. Learn more about cross connections in ourindustrial cross connections brochure.

Cross connection device testing

Cross connection control devices must be tested at the time of installation, and then be annually tested by a certified tester. To learn more about the process for cross control testing, please see our frequently asked questions.
