The Town of Aurora will be implementing a mandatory Backflow Prevention Program, under Backflow and Cross Connection By-law 6213-19. To comply with the Bylaw, all industrial, commercial and institutional, and multi-residential property owners have to install a backflow preventer on the water supply line to their property. Multi-residential properties are those that have more than six units sharing a single water service.
The purpose of the Program
is to ensure that the Town continues to provide safe and high-quality drinking
water to our community by decreasing the chance of backflow.
Backflow happens when
water from private properties flows back into the municipal water distribution system.
These properties may have internal connections (called cross connections) to
water used for non-potable purposes. This can create unsafe situations because
of the potential for contaminants to flow back into the drinking water system.
receive information about the program by mail followed by Notices to Comply
with the Backflow and Cross Connection Bylaw.
The bylaw will require
industrial, commercial, institutional, and multi-residential property owners to
undertake the following at their properties:
Conduct a survey
The property owner will receive a Notice to Comply when the a Cross-Connection Control Survey is required at the property.
Select a qualified contractor.
Have the selected contractor survey the property to identify potential or existing cross connections within the plumbing.
As part of the survey, have the contractor classify the degree of hazard of your property.
Submit the completed Cross-Connection Control Survey to the Town.
Conduct a survey of the property every 5 years thereafter or whenever there is a change in use or ownership of the property
Install and/or test the backflow prevention device
It is the responsibility of the selected
contractor to determine the degree of
hazard and type of device to be installed. These must be done according to the
Canadian Standard Association - CSA B64.
The program will be rolled out in three (3) phases:
Phase 1 – Properties classified as a severe hazard
Phase 2 – Properties classified as a moderate hazard
Phase 3 – Properties classified as a minor hazard. Devices would not be required at these properties unless the property use and hazard level changes.
