We administer a Cross Connection Program to help commercial businesses and multi-residential property owners. The program:
  • Maintains a database of facilities, building owners and backflow prevention assemblies installed within the building along with a test history of each of those assemblies and notes from inspections.
  • Maintains a database of certified testers and installers of backflow prevention assemblies.
  • Ensures that equipment used by all certified installers and testers are calibrated annually.
  • Conducts cross connection inspections of new and existing buildings within the City of Edmonton.
  • Notifies our customers of past-due annual testing requirements.
