One major component of that program, the Rebecca Trunk Wastewa- ter Main, not only represented a major step in meeting future infrastructure demands for the region, but also for microtunneling in North America. The project involved more than 4 km (2.5 miles) of 1,200- and 1,350-mm (48- and 54-in.) 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 180 to 626 m (590 to 2,053 ), 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 en- vironment, the project helps raise the bar in what can be accomplished with trench- less technology. As such, it has been se- lected as the 2017 Trenchless Technology Project of the Year for New Installation. " The project was completed in a highly congested and affluent area, so digging up roads and taking out large numbers of established trees would have been very difficult to do" said Paul Headland of Aldea Services, the trenchless design consultant for the project . " Trenchless construction was really the only way that we could ac- complish the goals of upgrading the infrastructure while minimizing dis- ruption to residents and businesses while accommodating the project spe- cific design constraints."
