Improved Water Treatment System Benefits Environment


November 25, 2011 – The City of Thunder Bay proudly celebrated today the completion of the Ultraviolet Disinfection Project at the city’s Water Pollution Control Plant. Jay Aspin, MP for Nipissing-Timiskaming, on behalf of the Honourable Tony Clement, Minister for FedNor; Keith Hobbs, Mayor of the City of Thunder Bay and Pat Mauro, Manager of Engineering for the City of Thunder Bay, were pleased to see this important community project reach fruition.

"Supporting sustainable growth and keeping our environment clean is important for Ontario's northern and rural communities,” said MP Aspin. "This significant project has equipped Thunder Bay to treat its wastewater with state-of-the-art technology and processes, improving the quality of life of residents living in and around the city."

"This project ties into the City's Clean, Green and Beautiful policy. It is a perfect example of how we are using partnerships to make Thunder Bay an even better place to live,” said Mayor Hobbs.

The Ultraviolet Disinfection Project eliminates the need for the use of chlorine to disinfect the treated wastewater before it is released back into the environment. The new process requires no chemical handling, adds nothing to the water but UV light and is better for the environment. With the new treatment in operation, approximately 20,000 kilograms of chlorine will no longer be discharged to the environment on an annual basis.

This project represents the final component of the wastewater treatment upgrades identified in the City's Pollution Prevention and Control Plan (PPCP). Through the Canada Strategic Infrastructure Fund (CSIF), the Government of Canada invested up to $25 million to support these upgrades, which ensure that there is a higher standard of treatment for wastewater. The City of Thunder Bay contributed the balance of the total eligible project cost of $75 million.

Other work included upgrades to the Water Pollution Control Plant from primary to secondary treatment and improvements to the sewer collection system.

With the final portion of this project now complete, residents of Thunder Bay and the surrounding communities, which rely on the Great Lakes for their supply of potable water, will benefit from a healthier lake environment and improved conditions of the lake’s ecosystem.
