Project overview

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.
