Sewer Rehabilitation starts Next Week!

Until about September 2nd, Several areas in the Ward will be affected by Sewer rehabilitation projects conducted by the City of Toronto.

Work Details

Inspection of Main Sewer / Inspection of Lateral Sewer

The inspection of the sewer system will involve sending a closed circuit TV (CCTV) camera into the sewer pipes to take images of different pipe segments. In order for the CCTV inspect the sewers, it is necessary to first flush the sewers with high pressure water and remove debris using vacuum trucks. For each segment of sewer, the work should take up to 10 hours depending on the length and condition of the sewer pipe being inspected.

Relining of Main Sewer

Re-lining of main sewer segment(s) requires special materials and equipment such as blowers, air compressors, and/or power generators. For each segment of sewer, the work should take up to 10 hours depending on the length and condition of the sewer pipe being addressed.

Relining of Lateral Sewer

Re-lining of lateral sewer segment(s) requires special materials and equipment such as blowers, air compressors, and/or power generators. For each lateral sewer, the work should take between 1 to 2 hours depending on the length and condition of the sewer pipe being addressed. The method of rehabilitating the existing sewer service connection is primarily trenchless, however, an excavation to install a City cleanout at the streetline (where City property meets private property) will be completed by the contractor prior
to lining the sewer connection.

*Please note that dates for sewer works may change slightly contingent on weather and other conditions.

The rehabilitation process will consist of several site visits by the contractor utilizing a variety of equipment for different stages in the lining procedure. The contractor will inform to homeowners and/or residents about specific dates and type of work with at least 48 hours in advance.

What to Expect During Sewer Works

The City will make efforts to reduce the impacts because of the sewer inspection and sewer relining. During inspection work hours, there will be some temporary inconveniences to the local community. Residents may experience noise caused by the flushing and the removal of debris from the sewer pipes by vacuum trucks. Once the flushing and clearance of the sewers is complete, the CCTV inspection work is not expected to cause any noise impacts.

Work Hours: Sewer works will take place from 7:00am to 7:00pm, Monday to Friday,
and will not take place during statutory or other major holiday observances. For
certain segments of sewer pipe, the inspection or relining work cannot take place
during the day due to conflicts with the traffic and TTC services (e.g. streetcar routes)
and other issues. These segments of sewer will be rescheduled and additional notice
will be provided for weekend/overnight work, if required.

Odor during Inspection: Please be aware that you may experience odors from
flushing activities of the sewer on their street. These odors are of short duration in
nature, and will diminish as the flushing is completed. If you smell odors
after the work, open all windows (where possible) and please contact our office so that we may inform the appropriate city staff.

During re-lining work hours, there will be some temporary inconveniences to the local community. The City asks to residents please limit the usage of their water services (i.e.: sinks, showers, and toilet flushing) while sewer work is being done, in order to facilitate a smooth operation. Once the re-lining and clearance of the sewers is complete, the CCTV inspection work is not expected to cause any noise impacts.

The sewer reconstruction process involves the use of a liquid thermosetting plastic resin which contains a substance called styrene. You may smell these styrene fumes while the City contractor personnel are working in your area, but don’t be alarmed. Humans detect styrene odors at a concentration of approximately 0.017-1.9 parts per million (ppm) which is well below the permissible limit of 20 ppm for the work place (8 hours per day, 5 days per week) set by the Ontario Occupational Health & Safety Act and National Institute for occupational Safety and Health of USA.

The odors reaching homes may be the result of a dry or broken plumbing wastewater trap in the home. The purpose of the wastewater plumbing trap is to maintain a water
barrier in the pipes to prevent all sewer odors from entering the home. In rarely used
drains (such as floor drains), the water in the trap can evaporate over time resulting
in no water barrier to prevent the odors from entering the home. A suggestion may be
to pour water (about a gallon) down all floor drains or rarely used drains (sinks, tubs,
showers etc) to ensure that a water barrier is maintained in the trap. If this does not
work, then it is very likely that residents have a trap that requires repair.

Traffic Management: Efforts have been made to manage traffic in the area for the
safety of workers, road users and residents. This includes adding Local Access
signs, revising traffic signal times and informing the public of alternate routes to use
through twitter.

Road and Sidewalk Access: In order to complete the work in a safe manner, there
will be road and sidewalk restrictions within the inspection work area.

Driveway Access: The contractor will notify you of any temporary restrictions to
residents’ driveway access. If properties have two entrances, one entrance will be
kept open at all times. Access for emergency vehicles will be maintained at all times.

Accommodation: Residents that require accommodation must contact the City
Inspector to arrange for access during the inspection period.

Parking: Residents may park outside of the inspection work zone. City Parking Officers will be advised not to issue tickets for “Parking in Excess of 3 Hours” on affected streets.
Tickets will be issued for all other violations, such as parking too close to the corner
or fire hydrants and other restricted area. Parking in the active work zone is not permitted due to space requirements for inspection equipment and materials. If resident’s parked vehicle affects the construction work, it will be re-located with no charge to the owner. Residents should contact parking control for the location of their vehicles at 416-808-2222.

Garbage & Recycling: Residents should follow their normal routine. If required, the
contractor will move bins to an appropriate location and return them.
