Microtunneling Under Pearson Airport - Twinning Etobicoke Creek Trunk Sanitary Sewer

Pearson Airport in Toronto is one of Canada’s largest and busiest airports, which serves approximately 41 million passengers, and has around 443,000 flights a year. This project was needed by the Region of Peel to complete a critical infrastructure link underneath runways and taxiways on the airport grounds. The Greater Toronto Airport Authority (GTAA), which manages the airport, could not allow major disturbances to its operations, especially considering that Pearson is the busiest airport in the country. Interrupting the 24/7 operations for construction is not an option, which is why microtunneling was ideal for the twinning of the Etobicoke Creek Trunk Sanitary Sewer. The microtunneling portion of this project was started in October of 2015 and was completed in December 2015, without a single disturbance. 575m of DECAST microtunneling pipe was installed, ranging in size from 1650mm to 1800mm, up to 10m below the active runway and two nearby active taxiways. The Region of Peel will have the ability to use either or both of the twinned sewers at any time. This will allow flow to be diverted into one sewer and allow inspection or rehabilitation of the other.
