Toronto's Coxwell Sanitary Trunk Sewer bypass now in operation
The Coxwell Sanitary Trunk Sewer (CSTS) bypass is now in service. Completion of this phase of the project means that one of the most critical sanitary trunk sewers in Toronto is now structurally and operationally sound.

Originally built in the late 1950s, the CSTS services approximately 750,000 residents in the central part of Toronto, carrying 400 million litres of wastewater a day to the Ashbridges Bay Treatment Plant.

In 2008, an assessment of the CSTS determined that a 60-metre section located near Coxwell Boulevard and O'Connor Drive was damaged and needed to be repaired or replaced. After significant technical analysis, it was determined that building a bypass around the damaged section was the best solution. Construction began in 2010 and the original trunk sewer was continuously monitored and in full operation during the entire construction period.

"Finishing the bypass tunnel is a great accomplishment. It demonstrates our commitment to put money into the infrastructure that people use every day," said Mayor Rob Ford. "I am pleased to announce that this critical piece of infrastructure is in service."

"This is a significant accomplishment and I want to thank everyone involved for completing this complex project safely," said Councillor Denzil Minnan-Wong (Ward 34 Don Valley East), Chair of the Public Works and Infrastructure Committee.

"The safe and successful conclusion of this construction project is great news for the local residents and all of Toronto," said Councillor Mary Fragedakis (Ward 29 Toronto-Danforth). "It's been a long construction project and I would like to extend my sincere thanks to the local residents for their patience."

"It's great news that the bypass is in service," said Councillor Janet Davis (Ward 31 Beaches-East York). "It was a difficult but critical construction project and while I know there's further site work needed in Taylor Creek Park, we all look forward to the future landscaping improvements."

A full report and presentation will take place at the March 19 meeting of the Public Works and Infrastructure Committee.
