The City of Toronto, with support from the Government of Canada, is making a significant investment in storm water infrastructure to protect the Fairbank-Silverthorn community from basement and surface flooding. The project will construct a three-kilometre long and 4.5-metre diameter storm trunk sewer, 17-km length of storm collector sewers and install 325 inlet control devices to control stormwater going to catch basins. When construction is complete, the new infrastructure will help to reduce sewer backups and basement flooding for more than 4,645 homes and provide flood protection to a 140-hectare area. The first contract to construct the storm trunk sewer and some storm collector sewers is underway. Several shafts have been completed and others are being constructed in anticipation of tunneling work, set to commence in early 2023.
