The Town of Newmarket has enacted a mandatory Backflow Prevention By-law on May 27, 2019 for all industrial, commercial and institutional, and multi-residential properties.
The purpose of the by-law is to ensure that the Town continues to provide safe and high-quality drinking water to our community by decreasing the chance of backflow, flowing into the public system.
Backflow happens when water from private properties flows back into the public system. These properties may have internal connections (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.
It is important to note that the Town of Newmarket has collaborated with BSI Online to enhance the management of the Cross Connection/Backflow Prevention program. Property owners with installed devices are required to have their bacflow prevention devices tested annually by a qualified individual and to submit the test results online via BSI Online.
If you are a property owner classified as industrial, commercial, institutional or multi-residential, you must complete a survey every five (5) years from the date of the initial survey, and annual testing of your backflow devices is mandatory by a licensed backflow tester.
You will receive a notification from BSI Online regarding the due date for your backflow testing. It is necessary to provide a copy of this notification and/or your Customer Confirmation Number (CCN) to your tester. your tester will be obligated to submit the results to the backflow test online through the BSI Online web portal.
Please be advised that as of February 1, 2025, paper copies of test results will not longer be accepted.
