Duffin Creek Water Pollution Control Plant named one of the best in Ontario

WHITBY, ON August 15, 2013 – The Duffin Creek Water Pollution Control Plant (WPCP) in Pickering has been recognized as one of the best wastewater treatment plants in Ontario in Ecojustice’s Great Lakes Sewage Report Card 2013.

Duffin Creek WPCP, which is jointly owned by York and Durham Regions, earned a B+ ranking in the report card, second only to Peel Region in Ontario. Ecojustice’s Great Lakes Sewage Report Card is an independent review of municipal sewage treatment in the Great Lakes.

“Durham and York regions have invested hundreds of millions of dollars in the past few years to improve the quality of treated water discharged into Lake Ontario and help protect one of the foremost environmental assets in Durham Region,” said Cliff Curtis, Commissioner of Works for Durham Region. “We are proud that Ecojustice–an independent environmental association–has recognized us for our commitment to environmental protection.”

Duffin Creek WPCP is a sophisticated plant that does not release untreated sewage into Lake Ontario, even during high rainfall; it meets or exceeds all provincial and federal treatment regulations; and it generates renewable energy, significantly reducing its reliance on external energy sources. The plant recently underwent a $628 million expansion to accommodate growth in both Durham and York regions. The expansion included the construction and installation of new technologies to provide an enhanced treatment level related to the removal of higher levels of phosphorus; and a new, state-of-the-art solids-handling facility, which eliminates the need to truck bio-solids to landfill, and provides a by-product for use in the local cement industry.

“We are thrilled to be recognized by Ecojustice as one of the best wastewater treatment plants in Ontario,” said John Presta, Director of Environmental Services. “Our employees take pride in delivering wastewater services to residents of Durham and York regions, while protecting Lake Ontario in a sustainable manner.”

The Duffin Creek WPCP was one of 12 Ontario wastewater treatment plants to be analyzed as part of the Great Lakes Sewage Report Card 2013. To view the full report card, visit and select the following headings: Publications > Great Lakes Sewage Report Card.
