Landfill Capacity Reclamation

Name of Project: Landfill Capacity Reclamation
Location: Township of Faraday, Ontario

Assignment

By 2009, the landfill in the Township of Faraday was running out of space and the community needed to find additional capacity. BluMetric (formerly WESA) was able to work with the Township to develop and implement an innovative alternative to creating a new landfill.

After considering many options, and extensive consultation with the community, BluMetric identified landfill capacity reclamation as the most cost effective solution, and potentially saving the Township $2 to 4 million over the extended lifetime of the landfill.

The landfill capacity reclamation option also made the best use of the existing landfill site (i.e. the footprint of the site did not need to be expanded) and offered the advantage of not generating the additional truck traffic on local roadways that would occur if the landfill was to be converted into a "transfer station".

Landfill capacity reclamation consists of the following steps:

  1. Excavate previously disposed material.
  2. Screen the material to separate the fine soil material from the true garbage.
  3. Separate the garbage into materials that can be recycled and those that need to be permanently disposed.

The waste to be disposed is compacted into the landfill at a higher density. The fine soil material is used as cover material.

The first phase of this project processed about 15,000 cubic metres of waste and regained about 50% of that volume. This will extend the life of the landfill for another 20 to 25 years.

During the reclamation process, the landfill remained open for use.

Other aspects of the project involved the control of environmental measures:

  • Surface water management
  • Odour control
  • Dust control
  • Leachate control
  • Installing berms and
  • Installing silt curtains

BluMetric will again provide engineering and project management services to the Municipality of Faraday in the second phase of extending the capacity of the operating life of its landfill. Based on the successful first phase results, it is anticipated that the second phase will extend the operating life of the landfill by another eight years. This will let the Municipality project waste disposal costs more confidently and defer for many years the need to find, design, and construct a new landfill facility. As in the first phase, the second phase will include excavating previously disposed materials, extracting those that can be recycled, and using more efficient disposal and compaction practices.
