The Duffin Creek Water Pollution Control Plant is located on the shores of Lake Ontario in Pickering. This is a conventional activated sludge plant that provides treatment of wastewater and sewage sludge received from the Regional Municipality of York and the Regional Municipality of Durham. This project was an expansion of the existing WPCP plant to a capacity of 630 ML/day to satisfy population growth in both regions, and to meet more stringent treatment regulations. The project involved the stage 3 solids process expansion, consisting of new dewatering and incineration facilities. The Dewatering Building is LEED Gold certified and is the largest LEED Certified building built at a WPCP in Ontario. The fluidized bed incinerators are the largest supplied in the world using a hot windbox with refractory arch distributor.

Kenaidan self performed 32,000 m² of formwork, 11,000 m³ of concrete and all mechanical installations.
