Lining operations for the next sewer section (East Section):
As early as the Week of February 20

Sewer lining takes place on a 24 hour schedule.


WHAT WORK IS TAKING PLACE?

  • To increase the durability of local sewers during mining operations at Avenue Station, sewer sections in the vicinity of station construction zones will be lined using the Cured-In-Place Pipe (CIPP) process.

SEWER LINING WORK

  • A new work zone will be set up in the roadway between Eastbourne Avenue and Lascelles Blvd on the north side of Eglinton Avenue.
  • The work zone will be used to accommodate the machinery used to insert the flexible lining membrane into the sewer, including a generator, boiler, compressor and sometimes a hydro-vacuum truck.
  • This will be permanently in place for approximately 1 week.
  • This new work zone will reduce the available lanes of traffic on Eglinton to one in each direction.
  • Some on street parking on the south side of Eglinton between Eastbourne Avenue and Lascelles Blvd will be impacted during this work.
  • Lining operations will temporarily seal property sanitary lines to the main sewer. There may be short durations during the work when local residents and businesses will be advised to refrain from water usage. Affected properties will be provided notice at least 24 hours in advance.

WHY USE THE CIPP PROCESS FOR SEWER LINING? 

  • The CIPP process is a minimally invasive method of sewer repair and rehabilitation that is commonly used throughout the City of Toronto. Using this process allows us to complete the work through existing maintenance holes without excavating the entire sewer up through the road.

THE SMELL OF SEWER LINING RESIN

  • The CIPP process for sewer lining work uses a synthetic resin called styrene. 
  • When the resin is heated during the curing process, it has a very distinct chemical smell, sometimes described as bitter-sweet. While the smell is unpleasant, it is not harmful. 
  • You can prevent/minimize the odour from reaching your property by ensuring that you have water in your plumbing P-traps and floor drains. You may also wish to cover the floor drain with a wet cloth and place a flat heavy object over the drain.
  • For more information on styrene use in the CIPP sewer lining process, please download the Toronto Public Health Fact Sheet.

WHAT TO EXPECT

  • Residents and businesses near the work zone can expected to hear noise from generators, compressors, hydro-vacuum trucks, and other construction equipment. 
  • An unpleasant chemical odour may be noticeable during the sewer lining work, both in the vicinity of the work zone and sometimes in the buildings connected to the sewer being worked on. It is not harmful.
  • In very rare occasions, during the cleaning and preparation process, air pressure in the sewer can cause water to splash out through toilets, sinks or floor drains.  While this is highly unlikely, you can prevent any instance of it occurring by taking the following precautions: 
    • Close the lids on all toilet bowls when not in use.
    • Insert drain plugs in all sinks and bathtubs when not in use.
    • If you have a float plug in your floor drain or a backwater valve installed in your house, ensure that it is free of debris and operating properly.
    • Wrap the cover of your basement floor drains with plastic (i.e. a freezer bag). Place something heavy over the floor drains to keep the plastic covered floor drain covers in place.
