Protecting our Drinking Water - Public Open Houses on Backflow Prevention Program

October 3, 2008 – The City of Thunder Bay is implementing a Backflow Prevention Program to address the risk of backflow of water from private water systems into the municipal water supply. Public Open Houses will be held on Oct. 7 and on Oct. 9 to provide information about the design and implementation of the Backflow Program that is mandatory for buildings used for industrial, commercial, multi-residential or institutional purposes. Letters have been sent to City of Thunder Bay Waterworks customers inviting them to attend the Open Houses to learn more about the program and how it will be implemented.

Cities across Ontario are implementing Backflow Prevention Programs to address this requirement of the Provincial Safe Drinking Water Act. Backflow is the risk of contaminated water flowing back into the City's water distribution system. It can be prevented by installing the appropriate backflow prevention devices. All commercial, institutional, multi-residential and industrial facilities will be required to install a backflow prevention device.

Residential buildings, with less than 600m2 in gross floor area and less than three storeys will not be required to install a backflow prevention device at this time.

The Open Houses will be held:

Tuesday, Oct. 7, 2008
Current River Community Centre
450 Dewe Avenue
7 – 9 pm


Thursday, Oct. 9, 2008
West Thunder Community Centre
915 Edward Street South
7 – 9 pm 

The Building Division will be contacting individual property owners advising them of their date of compliance. Additional Open Houses will be announced as required.
