Backflow Prevention Program

The Town of Goderich is committed to protecting public health and maintaining the safety and quality of its drinking water system.

Under Section 19 (Standard of Care) of the Safe Drinking Water Act, the Town is legally required to take all reasonable steps to safeguard drinking water, manage potential risks, ensure distribution system security, and comply with regulatory standards.

The Ontario Building Code (Section 7) requires the installation of backflow prevention devices to protect potable water systems. In addition, the Ministry of the Environment, Conservation and Parks (MECP) requires municipalities to establish and maintain a formal backflow prevention program.

Together, these requirements ensure that effective measures are in place to prevent contamination and protect the municipal drinking water supply.


Purpose of the Program:

To protect the safety and quality of drinking water, the Town of Goderich requires certain properties to comply with its Backflow Prevention and Cross Connection Control By-Law. This by-law applies to commercial, institutional, industrial, multi-residential properties (as defined by the Ontario Building Code), as well as construction sites.

Property owners are required to install approved backflow prevention devices on water supply lines to isolate their buildings from the municipal water distribution system and prevent contaminants from entering the Town’s drinking water supply.


Program Objectives

The Town’s Backflow Prevention Program is designed to:

  • Identify cross connections where potable water may be at risk of contamination
  • Prevent backflow events that could compromise the municipal water system
  • Maintain an up-to-date database of properties with backflow prevention devices

Property Owner Requirements

Owners of industrial, commercial, institutional, and multi-residential properties must:

  • Complete a Cross Connection Control Survey
    A Certified Tester must conduct a survey of the property’s water system to assess contamination risks.
    • Survey results must be submitted to the Town within 14 days of completion
    • Surveys are required every five (5) years
  • Submit Survey Documentation
    Completed surveys may be:
    • Emailed to backflow@goderich.ca, or
    • Delivered in person to the Building Department, Town Hall, 57 West Street, Goderich
  • Install Backflow Prevention Devices (if required)
    Where a moderate to severe hazard is identified:
    • A plumbing permit must be obtained from the Building Department
    • A Certified Tester must install approved backflow prevention devices at required locations
  • Refer to the By-Law for Applicable Sectors
    A complete list of:
    • Sectors required to install backflow prevention devices can be found in Schedule A
    • Point-of-use cross connections can be found in Schedule B
      (Backflow Prevention and Cross Connection Control By-Law)
  • Submit Test Reports Annually
    • Backflow prevention devices must be tested annually by a Certified Tester
    • Test reports must be submitted within 14 days of testing
    • Reports may be emailed to backflow@goderich.ca or delivered to the Building Department

Residential Properties

Most residential properties are not affected by this by-law due to limited cross connections and lower risk. However, any property may be subject to the by-law if it is determined to pose a high risk of contamination.

Backflow is the undesired reversal of water flow against the normal direction. This can occur through back pressure or back siphonage.

Back pressure:

  • can occur when pressure in a private water system is greater than pressure in the Town of Goderich’s water distribution system.
  • can result in water from the private system forcing its way into the Town’s distribution system.
  • can be caused by pumps, elevated tanks, temperature increases in boiler systems, and other local pressure events.

Back siphonage

  • can occur when pressure in the Town of Goderich’s water distribution system is lower than pressure in a private system.
  • can pull contaminated water from the private water system into the Town’s distribution system.
  • can be caused by nearby fire-fighting or watermain breaks.

A Backflow Prevention Device prevents backflow and includes a reduced pressure principle assembly, dual check valve, double check valve and the like.

Cross-connection means any actual or potential connection between a potable water supply or system and any source of pollution or contamination and includes any by-pass, jumper connection, removable section of pipe, swivel or changeover device and any other temporary connecting arrangement through which backflow may occur.

Hiring a Certified Tester

Backflow prevention devices must be installed by a Certified Tester.

A Certified Tester is a person who is a certified backflow prevention device tester who has successfully completed a cross connection course in backflow prevention device testing at an accredited school as defined in the CSA Standard: CAN/CSA- B64.10-11/ B64.10.1-11, as amended, and is currently certified (current tester’s certificate)

Inquire with your local plumbing company if they have the applicable certification requirements to inspect, install and when necessary, remove, backflow prevention devices.

Installation

An Application for Plumbing and Site Services is required for all new backflow prevention installations and replacements. Permits can be requested at the front desk of Town Hall (57 West Street, Goderich) or downloaded online on the municipal website under Building Permits > Plumbing.

Where to install a backflow prevention device

Backflow prevention devices should be installed immediately after the water meter and by-pass piping. This ensures that water from the private plumbing system will not flow back through the meter into the municipal water supply.

There must be no branch or hose connections between the water meter/by-pass and the backflow device. Thermal expansion must be addressed within the private plumbing system as per Part 7 of the Ontario Building Code.

Reduced pressure (RP) devices cannot be installed below grade in a pit, chamber, or vault. Discharges must be directed to a sanitary sewer.

The Town of Goderich must be notified of any changes to a property’s hazard level (i.e., due to tenant/operational changes). See Schedule A of the Backflow Prevention and Cross Control By-Law for hazard levels by sector.

Copies of any records submitted to the municipality should be kept on-site for a minimum of seven years.

Testing

Backflow devices must be tested:

  • at the time of initial installation
  • within 72 hours after a device has been cleaned, repaired, replaced, serviced or overhauled
  • at least once a year

Testing can be completed by a certified tester. A Certified Tester is a person who is a certified backflow prevention device tester who has successfully completed a cross connection course in backflow prevention device testing at an accredited school as defined in the CSA Standard: CAN/CSA- B64.10-11/B64.10.1-11, as amended, and is currently certified (current tester’s certificate)

Annual backflow test results must be submitted annually to the municipality by a Certified Tester using the backflow prevention device test report. Submission of the backflow prevention device test report to the municipality must be within 14 days of completion.

Test Tags

A test tag that provides a historical record of test results must be attached to each backflow prevention device.

Tags will be provided by the Town of Goderich and contain the following:

  • Business name and address of property
  • Date of the device installation
  • Type of backflow prevention device installed
  • Manufacturer, serial number, and size of the device
  • Test date
  • Certified Tester’s name and certification number
  • Name of tester’s company

Surveying

Property owners will receive a letter requesting that they complete a cross-connection control survey to help the Town of Goderich ensure adequate protection has been assessed. The Cross Connection Control Survey is to be submitted to the municipality every 5 years.

The Cross Connection Control Survey Report must be completed by a Certified Tester and submitted to the Town of Goderich within 14 days of completion. The survey report must be signed by the Certified Tester as well as the facility owner.

Surveys must be updated at least every five years, unless otherwise specified by the municipality, or within 14 days of any increase in hazard level.

Cross Connection Control Survey Reports (submitted every 5 years) and Backflow Prevention Test Reports (submitted annually) can be delivered to the Building Department at 57 West Street, Goderich, or emailed to the Town of Goderich Building Department at backflow@goderich.ca.
