Cross Connection Prevention

The RDNO is committed to providing safe and clean drinking water. However, once the water is in the pipes we can't always protect water from backflow or cross connection contamination. To help ensure water remains clean and uncontaminated right to your tap, we have implemented a Cross Connection Control (CCC) Program.

A Cross Connection Control Program is a requirement specified by the Provincial government through the Interior Health Authority (IHA) as a condition of the Water Utility’s Permit to Operate. It also helps RDNO-GVW meet the requirements of the BC Drinking Water Protection Act and Canadian Drinking Water Quality Guidelines. Devices used to protect the water system from backflow contamination must be tested annually to meet CCC requirements.

For questions regarding your Cross Connection or Backflow Assembly, please contact the Cross Connection Officer at 250-550-3654 or via email at
