Toronto Sewer Rehabilitation Program
The City is undertaking a sewer rehabilitation project that will include a number of projects throughout Ward 13. The first project is scheduled for the week of January 11, 2016 and the program will continue into 2017. This work will involve flushing, inspection and re-lining of sewer lines with impacts to road and sidewalk access. Residents in an area where work will be occurring will receive notice at least 48 hours in advance. Each project is expected to take one to two weeks depending on the length of the sewer line being repaired, with work lasting between 2 and 6 hours a day.
Residents may experience some disturbance and inconvenience from noise and fumes from the flushing and relining process, restrictions to road and sidewalk access, and loss of on-street parking. Where driveway access is temporarily restricted, residents should receive notification. 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. Some work may take place over night where there are conflicts with traffic and TTC service, however additional notice will be provided for any required overnight work. If residents have any concerns about access to their homes or parking, they may contact the Field Ambassador or Project Manager.
Residents may experience two types of odours during the course of the work.
- · Odour from flushing activity: residents may experience odours from flushing activities on their street. These odours are of a short duration in nature, and will diminish as the flushing is completed. If residents notice odours during or after flushing work they should open all windows where possible and call the Field Ambassador or City of Toronto project manager for assistance. These odours may be the result of a dry or broken plumbing wastewater trap in the home (a water barrier in pipes that prevents sewer odours from entering the home), likely in a floor drain or rarely used drain in a sink, tub, or shower. Residents are recommended to pour a gallon of water down all such drains to ensure the water barrier is maintained. If this does not work, then they may have a trap that requires repair.
- · Odour from re-lining process: The sewer reconstruction process involves the use of a plastic resin that contains a substance called 'styrene'. Residents may smell this chemical while crews are working in their area. However, residents should not be alarmed as humans detect styrene odours 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 notice provided to residents will outline timelines of work, area of road affected, and information concerning possible noise and smells. Residents will also be asked to limit their use of water services where possible while work is being done.
