Duffin Creek WPCP Stages 1 & 2 Influent Pumping Station and Headworks
Client:  Regional Municipality of Durham
Prime Consultant:  CH2M HILL Canada Limited
Value:  $76.7 million

The Duffin Creek Water Pollution Control Plant is jointly owned by The Regional Municipalities of York and Durham and is located on the shore of Lake Ontario in Pickering. This plant serves the water pollution treatment needs of Aurora, Newmarket, Vaughan, Richmond Hill, Markham, Pickering, and Ajax. The plant currently discharges approximately 340ML of effluent water per day and has the capacity to treat 630ML/day.

As part of the existing plant's operational growth and capacity expansion, the scope of this project requires new construction of an influent pumping station, preliminary treatment building, flow metering building, and electrical building. Work also includes biofilter odour control system, phosphorus removal system, flow control chambers, channels, yard piping and site services, ductbanks, aerated grit tanks, electrical system, instrumentation and controls, and mechanical/process systems.

Kenaidan is self-performing 22,900m2 of formwork, 8,500m3 of cast-in-place concrete, yard piping, and the mechanical works on this project. This project is part of the ongoing expansion of the existing plant where Kenaidan recently completed the design build subgrade for this project as well as the Dewatering and Incineration facilities.
