York - King City Sanitary Sewage Pumping Stations


King City Contracts 4C, 7, and 8 included the installation of three sewage pumping stations to accommodate up to 10, 11 and 20 L/s of peak flows from their respective service areas and pump to an existing gravity sewer system. Two of the stations involved the construction of a wet well and a separate control building with a dry pit. These two stations each contained one duty and one standby pump with a standby diesel engine to run one of the pumps, and related process equipment, electrical, HVAC, lighting, and controls. The third pumping station involved the construction of a wet well and self-priming Gorman-Rupp pump system installed in the road boulevard, complete with related electrical and controls.


The Municipal Infrastructure Group Ltd. (TMIG) was responsible for the construction administration and site inspection for Contracts 4C, 7 and 8 including the three sewage pumping stations.  The construction of the pumping stations within existing residential areas required constant and careful attention to mitigate any concerns from the public. TMIG also worked with the contractors, Township and Region to prepare schedules for commissioning and to oversee the successful testing and commissioning of each facility. In addition TMIG prepared the operation manuals for each pump station to satisfy MOE requirements.


The installation of the pumping stations included directional drilling, significant ground water management, and various methods of shoring including tight sheeting and a slide rail system. The stations were installed with minimal disruption to local traffic and area residents.
