The Mill Street Sewage Pumping Station located at 18 Bay Street East is a critical piece of the Town's wastewater collection system. The station captures all wastewater generated west of Grey Street - including Thornbury and Lora Bay - and sends it to the Thornbury Wastewater Treatment Plant. The pumping station requires an extensive rebuild to increase its firm capacity and to replace mechanical equipment that has reached the end of its useful life.

The project scope includes but is not limited to:

  • Temporary bypass pumping of incoming wastewater
  • Removal and disposal of existing electrical and mechanical equipment
  • General refurbishments and renovations of the existing building
  • Construction of a pump station building extension connected to the existing building
  • Construction of a new wet well, and expansion of existing dry well
  • Construction/installation of all new electrical and mechanical components
  • Construction of new asphalt access lane
  • Site restoration

Why Now?

The Mill Street Sewage Pumping Station is at capacity and needs to be upgraded to handle current and future flows from the Thornbury Wastewater Service Area. The upgrades will also help to significantly reduce the likelihood of bypass or overflow events during severe storms.
