Backflow Prevention

When backflow occurs, harmful chemicals and bacteria can pass through unprotected cross connections and into public water supply, creating a public health hazard. A backflow prevention device is a mechanical apparatus that allows water to flow in only one direction. If an unprotected or untested backflow prevention device connection wasn't installed or maintained properly and caused a public health hazard, the responsibility party, owners or occupants, can be held liable for damages.

  • Conduct timely annual testing of backflow prevention assemblies on your property.
  • Isolate your water system from the publics through the elimination of unnecessary cross connections.
  • Protect cross connections that cannot be eliminated with an approved Backflow Prevention Device or Assembly.

Backflow Testing Requirements

As the City of White Rock transitions into the new water utility, we will be implementing the online submission of test reports. This is to make test submissions easier for the consumer or the tester as they will no longer need to obtain a blank test form. The City has contracted BSI Online to maintain all backflow testing submissions and newly installed or previously unregistered backflow preventors.

Testing will have to be completed by an individual who is certified by the British Columbia Water and Waste Association (BCWWA) and all back flow preventers shall be tested:

  • Annually
  • As required by the regulatory authority
  • Upon installation (please note: the fee for filing a new test report is not included with plumbing permits)
  • When cleaned, repaired or overhauled
  • When relocated

Get Certified

Certified testers will need to hold a White Rock Business License and register with the City's new contractor BSI Online to submit test reports online for a fee of $34. For new backflow device testing forms, please contact Engineering and Municipal Operations Department at 604-541-2181.
