Many communities (i.e. water purveyors) in BC have put in place cross connection control (CCC) programs to safeguard their water system from contaminated water flowing backwards into the public water system. CCC programs are generally supported by local CCC or water bylaws mandating measures to be taken to ensure that cross connections in the water distribution system are protected or eliminated. Programs typically monitor (to varying degrees) the installation, maintenance and field testing of backflow preventers within a distribution system. CCC programs are an important part of a multi-barrier approach to protecting safe drinking water.


The following is a list of water purveyors in British Columbia with a CCC program. If you have a technical question related to CCC in your area, or if the CCC/water bylaw for your area is not current, please contact your water purveyor directly.


List of community CCC programs and contacts.





If your water purveyor is not on the above list, please contact and encourage them to start a CCC program.

If your water purveyor has a CCC program and is not on the list, please let them know to contact the BCWWA and ask to be added.





A BCWWA CCC Administration/Education membership is available for community CCC program managers/administrators, CCC educators, backflow prevention manufacturer reps, and other positions related to cross connection control that are not actively engaged in the actual testing of backflow prevention assemblies, but would still like to remain associated with the industry.


If you apply for, or hold a CCC Administration/Education membership, you are not considered certified to field test backflow prevention assemblies. You are required to renew your CCC Administration/Education membership on an annual basis to remain a member and gain access to member benefits, but you are not required to recertify (i.e. you do not need to take the recertification exam) every five years.
