Niagara Falls Wastewater Treatment Plant Upgrades
All Niagara Region projects

About the project

Niagara Region has undertaken improvements for the Niagara Falls Wastewater Treatment Plant located at 3450 Stanley Ave. in Niagara Falls. The plant is a key asset within our wastewater infrastructure system. It serves about 107,000 residents and visitors throughout the year.

These improvements will ensure increased treatment performance, greater equipment reliability and improved ability to protect the environment by meeting provincial and federal requirements.

The project will consist of three phases.

• Phase 1: Secondary treatment upgrades

  Design of Phase 1 has been completed. Construction is scheduled for completion in June 2026 and includes:

  • Various improvements to grit, chemical and secondary clarifier systems
  • Replacement of the existing rotating biological contactors with moving bed biofilm reactors
  • Construction of new chemical and blower buildings
  • Construction of a new chlorine contact tank and dechlorination system
  • Improvements to plant access and electrical and water supplies
• Phase 2: Primary treatment upgrades

  Design of Phase 2 is in progress. Design is estimated to be complete Q1 2027 and construction is estimated to begin Q2 2027. This phase is expected to include:

  • Structural improvements to the primary clarifier tanks
  • Replacement of the primary clarifier sludge removal systems
  • Electrical and HVAC upgrades to meet current code requirements
• Phase 3: Raw sewage pumps and screen upgrades

  Design of Phase 3 has not started yet. The project is currently in the initial stages of feasibility study planning. Design details and construction timing are to be determined. This phase is expected to include:

  • A new raw sewage screening process
  • Upgrade to the raw sewage pumping station
