Queenston - St. Davids Wastewater Treatment Strategy
All Niagara Region projects

About the project

Niagara Region is completing a Schedule B Municipal Class Environmental Assessment and conceptual design study to determine the preferred solution for wastewater servicing in Queenston.

The study considers two servicing options:

  1. Complete necessary upgrades to the existing wastewater treatment plant in Queenston. These upgrades will maintain the wastewater services for that plant.
  2. Decommission the Queenston Wastewater Treatment Plant and construct new infrastructure to transport the wastewater to the Niagara Falls treatment system.

Work includes a servicing strategy review and an environmental assessment to evaluate the effects of upgrading the Queenston Wastewater Treatment Plant versus constructing:

  • A new Queenston pumping station
  • A new forcemain to the Niagara Falls system
  • Associated works to increase capacity of the two existing St. Davids pumping stations and forcemains

It also looks at alternative strategies to avoid or minimize impacts on the community and natural environment. The study considers the current and future needs as outlined in the Water and Wastewater Master Plan. The study is following the process outlined in the Municipal Class Environmental Assessment document (as amended in 2007, 2011 and 2015).
