Sherbourne Common is a 1.5-hectare public space in the heart of the East Bayfront redevelopment precinct of Toronto’s waterfront. Features included treating lake water and providing it to the proposed public art features and irrigating the system within the park. Portions of the pavilion building were utilized for the pump and UV disinfection equipment.
Scope of Services
TMIG provided full engineering, design, contract administration, and site inspection services for the park and its services. Services included the provision of potable water, sanitary, and stormwater infrastructure for the park, as well as grading and a pumping station (PS) and UV treatment facility.
The submersible PS was designed with a divided wet well to draw water from the different sources. Each cell within the wet well is equipped with a submersible pump, complete with associated discharge piping and valving for flexibility of operations. The pumps discharge into a common discharge header located within the PS’s basement. The basement also contains the remainder of the process equipment, including the UV units. The UV system consists of two units, each of which can disinfect at a flow rate of 70L/s, with spacial allowance to permit the future expansion of the UV system treatment capacity to 140L/s complete with flow, UVT, and turbidity monitoring. In both cases, the UV system was designed with standby capacity in the event one of the duty UV units is unavailable for service.
