Dewatering System at Avenue Station


Installation of the dewatering system designed for Avenue Station construction will begin in early May. Dewatering systems involve controlling groundwater by pumping to lower groundwater levels in the vicinity of the excavation.  The specific dewatering system for each station is selected based on local soil conditions as well as existing groundwater levels. Once installed, the system will operate 24 hours a day and function for the duration of the construction

Installation of the dewatering system at Avenue Station involves drilling wells at approximately 10 m intervals on the north and south sidewalks of Eglinton Avenue West from Braemar Avenue to Lascelles Boulevard. Trenching will occur to install piping to connect each well point. Work will be divided into sections and crews will work on one or two sections at a time.

Impacts related to this work will include lane closures and sidewalk closures.  Additional details will be communicated prior to each section of work.

Hours of work/What to expect

  • Installation works will occur during permitted hours, from 7:00 a.m. to 11 p.m.
  • Construction set-ups will be left in place overnight.


Traffic and Pedestrian Details

  • A sidewalk closure will occur on Eglinton Avenue West between Avenue Road and Highbourne Road.
  • Where possible, 1.5 m sidewalk will be maintained for pedestrians.
  • Pedestrian detours will be in place around other work zones.
  • Lane reductions will be in place on Eglinton Avenue West.
  • Parking spots will be impacted in certain areas to accommodate traffic flow with reduced lanes.
  • Any work required in Eglinton Park will be coordinated with appropriate authorities.


Transit Impacts

  • Short duration relocation of bus stops is done in consultation between TTC and Metrolinx to ensure construction can continue safely while minimizing impact on the community and customers. Please watch for posted notices indicating new information.
