Our team is always looking for new opportunities that push the boundaries of typical design, so when we were retained by the City of Cambridge to provide engineering and project management services for a new deep trunk sanitary sewer, we started visualizing how this could be accomplished.
The sewer is part of the construction of Intermarket Road, a new four-lane collector road. It will service a large drainage area and support development within Waterloo Region’s East Side lands.
Due to shallow groundwater levels, which were under artesian pressure in the vicinity of the Freeport Creek crossing, a trenchless option was used. The solution involved installing a 200-m length of pipe by means of microtunnelling. The remaining 750 m of pipe was installed using traditional open-cut methods at depths between 10 and 15 m.
This project was awarded Project of the Year from the Centre of Advancement of Trenchless Technologies (CATT), at the 2021 CATT Awards of Excellence.
