The Town of The Blue Mountains has initiated a Municipal Class Environmental Assessment to evaluate and select the preferred solution to address the need for the extension of a gravity sewer and associated sewage lift station, at the Town’s Craigleith Wastewater Treatment Plant (WWTP). Additionally, an assessment will be complete to determine if the septage and leachate receiving station should be relocated to the WWTP. The proposed work will include the following:

  • Extending the sewage collection system from the existing gravity sewer on the southern boundary of the intersection of Grey Road 21 and Highway 26 north within the Long Point Road allowance to the Craigleith WWTP.
  • Development of solutions for a new lift station to raise the wastewater from the new sanitary sewer into the treatment plant.
  • Developing solutions for the relocation of the septage and leachate receiving station from its current location on Lakeshore Road to the WWTP site.
  • Design of all facilities to accommodate imminent near-term and build out needs.

The gravity sewer along Long Point Road is considered a Schedule “A” project and may proceed; however, the pumping station and septage receiving station at the Craigleith WWTP on Long Point Road will be considered a Schedule “B” project. The proposed solutions will be evaluated considering natural, cultural, technical and economic environment, and the preferred solution will be selected in consultation with regulatory agencies and the public.

Why Now?

The Town’s sanitary sewer collection and pumping infrastructure within the Craigleith area requires upgrades and enhancements to meet the projected demands of growth in a sustainable manner.

Project Updates

November 14, 2023 - Amended Project File Report available for review

The initial notice of completion for this project was issued on March 30, 2023. Subsequent comments were received that resulted in the Town proceeding with an additional Cultural Heritage Assessment of the preferred alternative. This study was completed in September of 2023 and the final report was completed in early October 2023. There were no identified items of cultural significance identified through the additional investigations and this has been documented in the amended report.

View Amended Project File Report

If no additional comments are received or consultations are requested prior to December 13, 2023, the Town will consider the requirements of Schedule B of the Municipal Class EA Process to be satisfied to allow the project to proceed to implementation.  At this time, the plan is to proceed with detailed design in 2024 with construction of the proposed works planned for 2025 subject to budgetary and regulatory approvals.
