Backflow Prevention

In order to ensure the delivery of safe, clean drinking water to the residents and businesses within their boundaries, municipalities are passing By-laws requiring all Industrial, Commercial, Institutional and some Multi-residential properties to comply with the CSA Standard for the installation and maintenance of backflow prevention devices. The purpose of this program is to protect residents from harmful contaminants that may enter the water system through cross-connections or backflow.

The Backflow Prevention module ensures that the potable drinking water system is protected against the entry of any contaminants. This is accomplished through the installation of backflow prevention devices at potential sources of contaminants.

Backflow occurs as a result of back siphoning, back pressure or both. Back siphoning is a reversal of the normal flow of water caused by a negative pressure in the water line. Back siphoning occurs when there is a reduction or stoppage of main water supply pressure, typically due to nearby firefighting activities or water main breaks/repairs. Backflow can also occur when there is an increase in the downstream water pressure above that of the supplied water pressure referred to as back pressure. Backpressure can also occur when there is a direct cross-connection between the potable drinking water supply and another process line which has the potential to transmit a contaminant into the potable drinking water supply.

The Backflow Prevention module is applicable to industrial, commercial, institutional and multi-unit residential buildings/ structures.
