For over 20 years ending in 1982, the Oakville Fourth Line Landfill in the Regional Municipality of Halton received the town’s waste.
Subsequently, the Region constructed a new toe drain and leachate pump station to more effectively manage the accumulating leachate and protect the surrounding environment. The management strategy for handling the leachate included recirculating it at the landfill and hauling the leachate off-site by tanker truck for treatment.
To eliminate the need to haul and off-load approximately 40,000 to 55,000 cubic metres of leachate per year from the closed landfill facility, the Region engaged Associated Engineering to complete the preliminary and detailed design for a new submersible wet well leachate pump station and 100 millimetre force main (twinned for redundancy), connecting the station to the adjacent Neyagawa sanitary sewer.


Project Highlights
Choosing the force main routing and pump station design involved evaluating numerous factors. These included the presence and location of contaminated fill, unforeseen waste disposal areas, boulder, debris, and refuse within the working limits. In addition, consideration was given to the variable nature of the fill material, which would be controlled by selecting a less steep trench side slope or by providing lateral support to the trench walls. Special consideration was also given to the overriding environmentally sensitive areas and minimizing adverse effects on surrounding wildlife habitats.
We also provided contract administration and inspection services throughout construction.
