Town of The Blue Mountains' Backflow Prevention and Cross Connection Control Program

The Town of The Blue Mountains is taking a proactive approach to protect the safety of the drinking water provided to its customers by implementing a premise isolation backflow prevention program. The Town's Backflow Prevention and Cross Connection Control Program will minimize the potential for contamination of the Town's drinking water supply. The program involves identifying cross connections between potable and non-potable sources and ensuring that these connections are removed or that protective devices are installed to prevent the contamination of the Town's drinking water supply. 

All Industrial, Commercial, Institutional (ICI) and Multi-Unit Residential properties connected to the Town's municipal water system are required to participate. The Backflow Prevention and Cross Connection Control By-law 2013-31 came into effect on July 15, 2013. The By-law requires that all ICI and Multi-Unit residential owners have the following services performed by a qualified contractor in order to comply:

1. Cross Connection Survey

The property owner/occupant (for which the By-law applies) is required to have a qualified contractor carry out a cross-connection survey of all plumbing in each building or structure every five (5) years, or upon change of occupancy, and to submit a report to the Town's Backflow Prevention Coordinator.

2. Backflow Prevention Device Installation and Testing

The property owner is required to have the appropriate premise isolation backflow prevention devices installed as required, to have a qualified contractor perform backflow prevention device testing annually for each installed testable device and to submit a report to the Town's Backflow Prevention Coordinator.

The fee schedule associated with the Town's Backflow Prevention and Cross Connection Control Program is available for review and/or download to the right of the screen under "Downloads".

Approved Qualified Contractor Registry

The Town maintains a list of qualified contractors approved to perform cross connection surveys and backflow prevention device testing. The Approved Qualified Contractor Registry is available for review and/or download to the right of the screen under "Downloads".

It is also suggested that customers verify that contractors have appropriate insurance coverage and discuss all costs before proceeding with any work associated with the Backflow Prevention and Cross Connection Control Program. Contractors operate independently from the Town and are solely responsible for any work performed. All costs associated with the requirements of the Town's Backflow Prevention and Cross Connection Control Program will be the responsibility of the property owner.

Cross Connection Control Surveys and backflow prevention device test results will only be accepted for review when they are performed by an approved qualified contractor.

Definitions

Backflow: A reverse flow condition, created by a difference in water pressures, which causes potentially contaminated water to flow back into the municipal water distribution lines. Backflow occurs as a result of either backpressure or back-siphonage.

Backpressure: Can be created when a source of pressure, such as a pump, creates a pressure greater than the one supplied from the water distribution system.

Back-siphonage: When water flows in the opposite direction caused by a negative pressure in the water line. This can result in the reversal of flow between the public system and private plumbing.

Backflow Prevention Device: A mechanical device used to protect the water supply from contamination by preventing backflow, certified to the CAN/CSA B64.10 Standard.

Cross Connection: A permanent or temporary plumbing connection between drinking water systems and plumbing systems/fixtures that can contain liquids other than drinking water (i.e. gasses, non-potable water and other liquid substances). These connections are very common and can occur in every type of property whether industrial, commercial, institutional or residential. Some are more hazardous than others.

Premise Isolation: Separation of the plumbing system usually within a building or structure, from the Town's water distribution system.

Building Permit Requirement

A Building Permit is required for the installation of all premise isolation backflow preventers regardless of the size of the water service connection. All installations of the premise isolation devices and all related items shall be completed in accordance with the Building Code, Canadian Standards Association B64.10 series standard and manufacturer's specifications.

For additional information on obtaining a Building Permit, please visit the Building & By-law Services webpage or contact 519-599-3131 ext. 239, build@thebluemountains.ca.
