Following the completion of a Sewer Master Plan, Utilities Kingston retained J.L. Richards & Associates Limited (JLR) to complete a Schedule B Class Environmental Assessment (EA) to address the existing and future needs at the Days Road Sewage Pumping Station (SPS). The Days Road SPS is an important and significant facility for the collection and conveyance of communal sewage generated from the western portion of the City of Kingston (City), as it conveys 90% of the total sewage flow generated. Many of the station’s internal components were reaching the end of their intended service lives and needed refurbishment or replacement. In addition, the station did not currently have the capacity to accommodate future planned growth and development.

A strategic approach was adopted to update the future flows from the Master Plan to account for the City’s more recent experiences with extreme wet weather events. The preferred alternative determined through the Class EA process was to replace the pumping station on the existing site next to a recreational park with a new modern larger capacity station. Conceptual design was completed as a part of the Class EA to further advance the design concept, such that concerns from residents could be accounted for within a new design. This Class EA portion of the project was completed and JLR was subsequently retained to provide detailed design and contract administration services for the pumping station upgrades. An intricate sequencing plan was developed to maintain operation of the existing station while the new station is being constructed nearby.  Electrical servicing sequencing was particularly challenging based on service availability and configuration of the existing system.
