Rebecca Trunk Wastewater Main

The Rebecca Trunk Wastewater Main, not only represented a major step in meeting future infrastructure demands for Halton Region, but also for microtunneling in North America. The project involved more than 4 km (2.5 miles) of 1200mm and 1350mm (48" and 54") microtunnels within Oakville, an urban and affluent town along the shore of Lake Ontario. The project included nine microtunneling drives (eight curved) ranging in length from 180m to 626 m (590' to 2053'), with seven of the drives completed in rock.

Due to the length of drives, number of curves, difficult ground conditions and behavior, and congested urban work environment, the project helps raise the bar in what can be accomplished with trenchless technology. As such, it has been selected as the 2017 Trenchless Technology Project of the Year for New Installation.
