Client: Sunshine Coast Regional District
Location: Sechelt, British Columbia 



The Sechelt Landfill is a natural attenuation landfill that has been in operation since 1971. The site includes a municipal solid waste landfill, public drop off area, public weigh scales, and operational infrastructure. The landfill accepts approximately 13,000 tonnes of waste annually and serves the District of Sechelt, Town of Gibsons, Sechelt Indian Government District, and all of the electoral areas in the Sunshine Coast Regional District.

In 2017, XCG completed an updated Design, Operations, and Closure Plan to meet the 2016 Landfill Criteria and the requirements of the Operational Certificate for the site. The plan included fill planning, leachate management, surface water management, landfill gas management, an airspace estimate, and a landfill life assessment, as well as closure and post-closure planning and associated costing.

The key objectives of the plan were to:

  • Provide an updated fill plan which addresses the need to reduce leachate generation, optimize surface water controls and optimize available landfill airspace;
  • Provide a closure plan including implementing a low permeability cover system;
  • Provide a post-closure plan for the landfill; and
  • Reduce long-term environmental impacts associated with the landfill area.

The resultant Design, Operations and Closure Plan is a comprehensive and integrated design document which addresses all of the aforementioned objectives. The DOCP includes a detailed development strategy for the existing landfill footprint, providing approximately 172,800 cubic metres of airspace. Based upon population growth projections and fill rate assumptions presented herein, it is estimated that the Site will reach design capacity in 2025.
