Project overview

The Greater Toronto Airports Authority (GTAA) engaged MTE Consultants as the Prime Consultant for the detailed design of Tank #4 at the Central Deicing Facility (CDF). The primary goal was to expand the CDF’s capacity to store high-concentration glycol and enable efficient effluent transfer between Tank #4 and the existing Tanks #2 and #3. To support the project’s mechanical and electrical components, MTE collaborated with H.H. Angus and Associates.

MTE's Involvement

As Prime Consultant, MTE led the design and coordination of all project components. Under MTE’s direction, subconsultants contributed mechanical and electrical expertise to ensure that the design met rigorous technical and operational requirements.

During the preliminary design phase, MTE explored multiple design concepts, including tank sizing and positioning, interior waterproofing systems, separation of high- and low-concentration glycol chambers, structural and mechanical connections to Tank #3, and integration with the existing glycol management system.

The detailed design phase included a new concrete tank with a capacity exceeding 5,000,000 litres, along with pumps and valves for effluent transfer. The design also incorporated new catchbasins and manholes to drain the snow area above the tank, and connections to existing storm and sanitary sewer systems for overflow management.

The project presented several complex challenges, including:

  • Designing for heavy snow loads in the “Pink” snow disposal area
  • Relocating existing site services
  • Ensuring effective interior waterproofing
  • Adhering to an accelerated design schedule
  • Accommodating a compressed construction timeline

MTE’s team successfully addressed each of these challenges, delivering a efficient solution aligned with GTAA’s operational needs and project timelines.
