Step-by-Step Process for Cross-Connection Control

Halton Region sends letters to property owners about the Cross-Connection Control Program as per Cross-Connection Control By-law #61-11. This page provides the necessary information and steps you need to take to comply:

  • Conduct a Cross-Connecton Control survey
  • Install a backflow prevention device
  • Testing frequency for backflow prevention devices
  • Fees
Conduct a Cross-Connecton Control survey

If you don't have a backflow prevention device(s) installed or don't know if you have one:

  1. Complete a Cross Connection Control survey, using an authorized OWWA accredited tester.
    We advise that you conduct a full internal cross connection survey to identify any internal plumbing cross connections that may require backflow prevention devices.
  2. Mail the completed survey to Halton Region within 60 days of receiving your letter, along with a $106.00 + HST administration fee, to:
    • Attention: Cross-Connection Control Program
      Halton Region
      1151 Bronte Road
      Oakville, Ontario L6M 3L1
  3. Halton Region will review the completed survey, determine the level of hazard as moderate or severe and will advise you of any further action required.*
  4. You will be required to repeat the survey every 5 years, at time of ownership change, or rezoning of property.

    * Halton Region staff will send you a letter after the survey is reviewed. Based on the survey results, you will be advised of the type of backflow prevention device required to be installed at your property.

If you already have a device(s) installed at the time you receive a letter from Halton Region:

  1. You must still conduct a cross connection control survey using an authorized OWWA accredited tester and ask the tester to test any premises isolation backflow prevention device(s).
  2. Submit both the survey and the testing and inspection report to Halton Region, with ONLY a $53.00 + HST administration fee per premises isolation backflow prevention device. The survey fee of $106.00+HST is waived.

Existing Fire Suppression Systems

All existing moderate or severe hazard fire suppression systems require the installation of a backflow prevention detector assembly and owners must submit testing and inspection reports to Halton Region on an annual basis.

Install a backflow prevention device
  1. Select a contractor to install the backflow prevention device. The Region recommends you obtain several quotes and does not endorse or provide a warranty of the services, prices, or qualifications. You may also wish to ask your contractor to give you recommendations on suitable backflow prevention devices to ensure full protection of your private plumbing system.
  2. Prior to installing a backflow prevention device, you must obtain a plumbing permit from your local municipal building department.

    Halton Region has standardized drawing specifications for the installation arrangement of the water meter and the backflow prevention device. Please have your contractor use these standard drawings when submitting for a plumbing permit.

    Locate an authorized OWWA accredited tester to test your backflow prevention device(s).

  3. Please submit the completed original Test Report, a copy of the signed off plumbing permit and the test fee (reduced to $53.00+HST) payable to:
    • Attention: Cross-Connection Control Program
      Halton Region
      1151 Bronte Road
      Oakville, Ontario L6M 3L1
  4. A backflow prevention device Test Tag must be filled out at the time of testing and is valid for five years. Do not remove the tag. Example Test Tag
  5. The property owner is responsible for ensuring all reports, permits and fees are sent to Halton Region.
  6. The date of the initial test will become the anniversary date for future testing of the devices on an annual basis. This means the subsequent annual test results must be submitted to the Cross-Connection Control Coordinator, no later than the anniversary date of the initial test report. Halton Region will send you a reminder a month before your annual test is due.

Information for Installers:

  • Halton provides standardized Cross-Connection Control Surveys, Testing and Inspection Reports and Backflow Prevention Device Test Tags to all authorized OWWA accredited Testers listed with Halton Region.
