Backflow - Cross Connection Control Program

Purpose of the Program

In order to ensure the delivery of safe, clean drinking water to residents and businesses within the municipality, the Town of LaSalle has instituted strict criteria under which property owners are allowed to connect to the Town's water supply.

Backflow PreventionBackflow Preventer

Safe clean drinking water is delivered through a network of water mains. In order to protect the public, the Cross Connection and Backflow Prevention By-law #7847 takes a proactive approach towards preventing any contamination entering the system.

Protecting drinking water quality is a top priority and the installation of backflow prevention devices can prevent the possible contamination of the Town's drinking water system.

Backflow is the undesired reversal of water flow against normal direction. Backflow occurs as a result of Back Pressure or Back Siphonage.

Back Pressure occurs when the pressure in a private water system is greater than the pressure in the Town's water supply system.

Back Siphonage occurs when the pressure in the water supply-system is lower than a private-systems' pressure. This can result in the reversal of flow between the public and private system.

Backflow Prevention Devices and Annual Testing

There are several different types of devices to address varying types of hazards. Most devices must be tested annually to ensure that they are operating properly. The By-law requires that only Authorized Certified Contractors (PDF), may test and install backflow prevention devices. The Certified Contractor will complete the Backflow Prevention Report Form Annually and submit it to the town.
