Waste Water

photo of Water Pollution Control Plant BAF BuildingThe City of Thunder Bay is committed to protecting the integrity of Lake Superior. The City's Atlantic Avenue Water Pollution Control Plant has been expanded and retrofitted, creating a new state-of-the-art Secondary Sewage Treatment Plant. This upgrade was one of the main recommendations of the Pollution Prevention and Control Plan adopted by the City in 1999. The opening of the new facility launched a new era in the protection of Lake Superior.

Wastewater System 20-Year Financial Plan
Presented to City Council as a "first report" (for information) on Jan. 14, 2015, the Wastewater System Financial Plan outlines the projected operating and capital plan for the next 20 years, with the goal of achieving financial sustainability, full-cost recovery and affordability for consumers while maintaining the City’s existing service levels for sewage collection and treatment. The forecast demonstrates that these goals have been met through a combination of limiting increases in the sewer surcharge rate and the issuance of new debt.

New Process
In addition to secondary sewage treatment, the new facility uses nitrification to eliminate ammonia from the waste water. The new process provides secondary treatment, phosphorus removal, sludge digestion, and de-watering for the City's wastewater.
