The Dewatering Vendor of Choice for Toronto LRT Projects

The success of the Eglinton Crosstown LRT (Light Rail Transit) project (also known as Line 5) in Toronto, where we have provided dewatering services to great effect on 12 of the 14 stations, has led to WJ becoming the dewatering vendor of choice for large LRT projects in the city.

Finch West Station

The Finch West Station includes a deep connection to the existing subway station and an underground track crossing – in short a deeply complex project, that will require the installation of deep wells, wellpoints and eductor wells. Fortunately these types of projects are second nature to WJ and perfectly demonstrate our creative and flexible approach to providing successful and efficient dewatering solutions that we have shown on thousands of project in Canada and elsewhere across the globe!

Humber College Station

The Humber College station, located adjacent to Highway 27 will be another opportunity to demonstrate many of the dewatering techniques that were used to great effect on the deep excavations of the Eglinton Crosstown project.

Finch West LRT

Building on the success of this project, WJ have recently begun work on the Finch West LRT project. The Finch West Project (also known as Line 6) continues the expansion of public transit services in Toronto and is expected to carry some 40,000 passengers per day by 2031. Our initial works on the project will cover the two new underground station that are due to be constructed: the new terminus at Humber College and the new interchange terminus at Finch West, where the new line will connect with the Line 2 extension to York University.

We are proud to be given the opportunity to contribute to this exciting project, and the continued expansion of public transit projects in Toronto, and look forward to its successful completion, and having the opportunity to hop on board!

Lusail Expressway

Lusail Expressway is one of the largest among 30 road projects to be developed as part of Qatar’s seven-year Expressway Programme.

Initiated in 2010 to connect people and places across the city of In 2010, Qatar’s seven-year Expressway Programme consists of 30 road projects, with the aim of connecting people and places across the city of Doha and wider Qatar. Nine hundred (900) kilometres of new road network involving a number of underpasses, flyovers and multi-level interchanges are expected to be delivered.

The Lusail Expressway is one of the biggest to be developed, with 5.3 km of four-lane highway in both directions, two cofferdams and three major interchanges; the Al Wahda Interchange, Onaiza Interchange, and the Pearl Interchange.

The Expressway will also have two service lanes in the multi-level interchange areas, and include a complex network of tunnels, flyovers and junctions in order to meet the future traffic demands by providing easy and speedy connectivity.

Dewatering of the project proved a challenge, as unforeseen and unexpected cavities and fissured flows were encountered, with at the peak flow in excess of 10,000 m3/hr for one of the underpasses! However, WJ rose to the challenge and dewatering was achieved with deepwell system and supplemented with sump pumping.
