MTE's Involvement
Construction included the installation of dual forcemains (450 mm and 300 mm in diameter) and a deep 525 mm gravity trunk sewer to connect the East Side Lands to the new pumping station. The project required extensive environmental coordination and the use of specialized construction techniques to address complex subsurface conditions.
MTE was retained to provide civil engineering and surveying services for both the design and construction phases of the Speedsville Pumping Station and its supporting infrastructure. Our scope included surveying, site grading, capacity analysis, groundwater and geotechnical investigations, and the detailed design of the forcemains, trunk sewer, and pumping station.
To ensure regulatory compliance, MTE managed the site plan and building permit approvals from the City of Cambridge and coordinated with the Ministry of the Environment, Conservation and Parks (MECP) to secure Environmental Compliance Approval. We also engaged with the Grand River Conservation Authority to address environmental considerations specific to the station’s location.
The project site presented significant geotechnical and groundwater challenges. MTE implemented a high-compaction clay barrier wall and a three-pump trench dewatering system to manage groundwater during excavation. The depth and proximity of the new trunk sewer to existing infrastructure required advanced methods such as trench boxes, trenchless installation, side rail shoring systems, and meticulous construction sequencing to ensure safety and efficiency.
Throughout construction, MTE provided ongoing support through tendering assistance, construction inspection, and contract administration. We also coordinated with subconsultants responsible for electrical systems, instrumentation, SCADA integration, and landscape design—ensuring the project met all technical specifications and municipal requirements.
The successful and on-schedule commissioning of the Speedsville Pumping Station enabled the Hunt Club subdivision to proceed as planned and delivered essential sanitary servicing capacity for a significant portion of Cambridge’s future East Side development.
