Study area
  • 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 a Schedule C Class Environmental Assessment (Class EA).
  • The recommended diversion solution consists of constructing an 11 km deep gravity sewer using a tunnel boring machine (TBM).
  • The preferred alignment for the construction is along Derry Road, Old Derry Road, Old Creditview Road and Creditview Road, from 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 planned TBM work.

Proposed Construction Timing

The earliest possible construction start date for the diversion trunk sewer is fall of 2018.
