Niagara-on-the-Lake Wastewater Treatment Plant
All Niagara Region projects

About the Project

A new treatment facility is being built approximately 800 metres west of the existing plant located on Lakeshore Rd. in Niagara-on-the-Lake. The new plant will:

  • Operate more efficiently
  • Help protect the environment
  • Reduce noise and odours
  • Ensure sufficient treatment capacity for the next two decades


The estimated cost of this project is approximately $43.2 million. Funding is equally split between three levels of government: Government of Canada (Building Canada Fund - Major Infrastructure Component), Province of Ontario (Building Together) and Niagara Region.

Decommissioning of the Current Facility

A separate Environmental Assessment was necessary to determine the preferred alternative for decommissioning of the existing Niagara-on-the-Lake Wastewater Treatment Plant.

Public and stakeholder input was requested as part of the decommissioning environmental assessment.
