- Drinking water can become contaminated due to what is known as, backflow.
- This contamination can occur because connections “crossed” between the drinking water supply and a contamination source, and contaminants “back flowed” into the drinking water system.
- In order to protect health and drinking water quality, the Ministry of the Environment enforces the Safe Drinking Water Act, which, among other things, imposes a statutory obligation on owners of drinking water systems to show due diligence in maintaining water quality.
- As a result, the Town of Lincoln recognized a need to address the risk of backflow into its drinking water systems from privately owned properties by implementing the Backflow Prevention Program, as set out under By-law 01-134 (as amended).
- Those properties with installed devices arrange to have the backflow prevention device tested by an authorized person, and submit test results online.
The main components of the program involve:
- A survey of the property to identify cross-connections, risks and the recommended type of backflow prevention device required
- Installation of the required backflow prevention device, where needed, under a Town of Lincoln plumbing permit
- Maintenance and annual testing of the backflow prevention device
Testing and Reporting
- Testing of the your backflow devices is required to be completed yearly by a licensed backflow tester
- You will received a letter from BSI and the Town regarding your backflow testing due date. You will need to provide a copy of this letter and/or your Customer Confirmation Number (CCN) to your tester.
- Your tester will be required to submit the results of the backflow tests online. There is a $14.95 fee for each test that needs to be filed.
- As of June 2018, paper copies of test results will not be accepted
Properties requiring the backflow prevention device:
Not all properties require the device. The By-law does not apply to single family homes, semi-detached homes, or townhomes.
