Guysborough Waste Management Facility

• Dillon Consulting Limited

» Scope of Project

As an extension to an initial feasibility study assignment, the Municipality of Guysborough retained Dillon to provide engineering, approval and planning services to support the establishment of a new 70,000 tonne/year regional “second-generation” (composite-lined) landfill located north of an existing first generation (Lincolnville) site.

» Execution

Dillon conducted detailed hydro-geological, biological, water quality and geotechnical investigations to confirm the suitability of the site. An archaeological survey was also conducted along with an aquatic habitat and plant survey. Preliminary design was completed and presented to the public for comment. Detailed design of the entire facility was completed and the drawings, specifications and tender documents were issued. The landfill incorporates a provincially-approved liner, stormwater control ponds, leachate pre-treatment lagoons and site buildings.
