Featured Project

Faro Mine Down Valley Seepage Interception System, Water Treatment Plant

Location
Faro, YT
Key Services
  • Water Treatment
Description

The site is now one of Canada’s most complex and significant abandoned mine remediation projects, expected to take approximately 15 years to complete, followed by 20-25 years of testing and monitoring after completion.

Located within proximity to the small community of Faro, the Down Valley Seepage Interception System (DV-SIS) Water Treatment Plant needed to prevent metal-contaminated groundwater from seeping into surface water and reaching fish-bearing streams.

 

Key Challenges
  • Installing an exceptionally advanced pumping system in a remote location.
Key Solutions
  • Two systems housed in Seacan containers were installed and tested before mobilizing to the site.
  • One container housed the electrical equipment, and the other housed the mechanical and pumping equipment.
  • The containers were shipped to a previously constructed pad and connected to existing intake and discharge lines.
  • Communication and high-voltage lines were run from the electrical container to the mechanical container on site.
  • It was designed to operate as a fully automated system (including automated control and monitoring) that could withstand extremely low-temperature conditions within the northern climate.
  • Given the area’s remoteness, detailed planning before installation and building a solid connection with the small community of Faro were critical factors to the project’s success.

An advanced pumping system installation involved civil, mechanical, and electrical services to install a sump, treatment pad, pump house, pumping system, conveyance pipeline, and a pump house and e-house to provide power. The groundwater collection and conveyance system was connected to three existing groundwater collection wells to capture the contaminated groundwater.

Vision:

A commitment to Indigenous Engagement, Benefits and Capacity Building was a strong focus for this project, as it is located within proximity to the traditional territory of the Kaska Nations (Ross River Dena Council, Liard First Nation and Kaska Dena Council) and upstream from the Selkirk First Nation.

Plan:

Milestone engaged Ross River Dena Council, the most proximate and impacted First Nation, and entered into a Business Employment and Training Memorandum of Understanding (BET MOU) with Dena Nezziddi LP, the economic development arm of the Ross River Dena Council.

Outcome:

The commitment made through these terms resulted in socio-economic benefits to the community through training, employment, revenue sharing, and the procurement of local goods, services and equipment.

Additionally, Milestone worked collaboratively with other Kaska businesses, including labour and equipment resources from Tse Cho Enterprises, to provide regional benefit.
