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

About the Project

Niagara Region has initiated a Schedule B Municipal Class Environmental Assessment Study and conceptual engineering design project to determine the best option for wastewater servicing in Queenston Heights.

The study will look at two servicing options:

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

The scope of work will include a servicing strategy review and an Environmental Assessment to evaluate the construction of:

  • A new Queenston pumping station
  • A new forcemain to the Niagara Falls system
  • Capacity increases to the two existing St. Davids pumping stations
  • Twinning of the St. Davids No.1 forcemain

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