What Work is Happening?

In advance of upcoming mining works at Oakwood Station, crews must install sewer linings to the existing sewer infrastructure on Eglinton Avenue West between Oakwood Avenue and Times Road.

Sewer lining is a process intended to increase the durability of the sewers. The liner is a flexible membrane that is placed inside the sewers. Lining is designed to be generally non-disruptive and eliminates the need for excavation of the entire sewer section.

To facilitate this work a number of lane closures are required. The work zones are 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.

·      Times Road at Eglinton Avenue West will be closed for approximately three (3) weeks, there will be no access from Times Road to Eglinton Avenue West.

·     One southbound lane closed on Oakwood Avenue for approximately ten (10) non-consecutive days

·      One eastbound lane closed on Eglinton Avenue West, west of Oakwood Avenue for approximately 24 hours

·      One northbound turn lane closed on Oakwood Avenue at Eglinton Avenue for approximately 24 hours

·      A minimum of 1.5m will be maintained for pedestrian walkways. Access to bus stops and businesses will be maintained at all times.

 Sewer  lining work will begin as early as February 13th, 2018 and take approximately three (3) weeks.

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.

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.
