Wastewater to be Diverted in Mississauga
Published December 15, 2016 at 4:24 am
If you’re a frequent user of Derry Road, either to get to and from work or if you’re in the trucking / logistics industry, you might want to know about a major wastewater project set to take shape in the area.
According to a recent public notice, the Region of Peel has identified a preferred strategy to divert a portion of wastewater from the east trunk sewer to the west trunk sewer as part of an Environmental Assessment (EA). The recommended solution to divert that wastewater consists of building an 11 km deep gravity sewer using a tunnel boring machine (TBM). A similar machine was used to dig the Eglinton Crosstown LRT route underneath Eglinton Avenue in Toronto.
The public notice goes on to identify where along Derry Road the construction will likely take place: Derry Road, Old Derry Road, Old Creditview Road and Creditview Road just east of Bramalea Road to Creditview Road and Highway 401. There will be a total of seven tunnel access shafts located along the sewer route to facilitate the work to be done by the TBM.
The earliest possible construction start date is in the fall of 2018. An electronic copy of the EA report is available for public viewing here (click on Environmental Assessments, then Current Water and Wastewater Project EA’s, then Mississauga). Hard copies will also be available at Region of Peel Headquarters at 10 Peel Centre Drive in Brampton, the brand new Meadowvale Community Centre/Library at 6655 Glen Erin Drive in Mississauga, as well as the Mississauga Civic Centre.

If you’re familiar with the operations of a tunnel boring machine and what deep gravity sewers are like, then you’d know you’re in for some long term pain along Derry Road. Peel Region has already been deep into another major water infrastructure project, the Hanlan Water Project, that has had construction going in the north-south direction of Peel Region for the better part of a year (currently Tomken Road is backed up into one lane starting at Courtney Park to Eglinton Avenue).
Now they’re planning to do an east-west connection to divert wastewater, which I feel could be more contentious should an incident occur and cause wastewater to leak out onto the surface. Hopefully, everything will be done to mitigate anything like that from happening as this project gets underway.
