Construction work starting in your area
Peel Region will be working in your neighbourhood to rehabilitate a large sanitary trunk sewer and associated maintenance holes. Sanitary sewers are underground pipes that carry wastewater from your home to a water resource recovery facility. Wastewater is created when water is flushed down the toilet or goes down the drain in your sink, tub, or shower. View attached map.
The sewer to be rehabilitated starts in the Hydro One corridor northwest of the Glen Erin Drive overpass at Highway 403. It runs under the highway and continues northeast, parallel to Highway 403, until it reaches the McCauley Green residential area.
To extend the service life of this sewer, Peel Region’s contractor will clean the existing pipe and install a new resin (plastic) lining inside it. This work is primarily completed using trenchless technology, which means the lining process will take place underground using specialized equipment and will not require open excavation along the length of the pipe. As part of this project, we will also be rehabilitating aging maintenance holes to ensure that the sanitary sewer system can continue to be accessed and maintained safely and efficiently.
Construction schedule
Construction is planned to begin on Monday May 19, 2025, and be completed by the end of August 2025. It will involve the following:
- Sanitary flow bypassing to transfer sewage away from the work.
- We will rehabilitate the sanitary sewer in sections and may spend a few days in each location to complete the work.
- It typically takes a few hours to three days to repair each single maintenance hole, depending on the work required.
- All work is under warranty for two years from the completion date.
Contractor and working hours
The work will be completed by Insituform Technologies Ltd and supported by consultant Robinson Consultants Inc., both under contract to Peel Region. This contractor’s normal working hours are from 7 a.m. to 7 p.m., Monday to Friday. These hours are consistent with the local municipality’s bylaws. We understand this may cause some inconvenience, but shorter working days would require this work to affect your neighbourhood over a longer period of time.
Overnight work
To minimize the overall duration of construction impacts, the City of Mississauga, under Noise Control Bylaw 360-79, has granted an exemption to allow sanitary sewer lining and sewage flow bypass work to proceed 24 hours a day, 7 days a week.
It is estimated that five 24-hour shifts will be required to complete the repairs outside the normal working hours. This continuous work is expected to occur between June 16th, 2025, and July 18th, 2025. Due to the technical requirements of the sewer lining process, work must proceed without interruption once started. By working continuously, we can significantly reduce the total time your area is affected by construction. We understand that extended hours may cause some disruption to your daily routine, and we apologize for any inconvenience. Every effort will be made to minimize noise during overnight hours, including the use of noise-dampening equipment wherever possible.
Odours
You may smell some odours while the synthetic resin inside the sewer cures. These odours are temporary and will dissipate within a few hours. You can prevent or minimize these odours by making sure you have water in all of your drains, including your basement floor drain. We recommend pouring a bucket of water down the floor drain and running the water in all sinks, showers, and tubs for a minute if odours are detected inside your home. To further minimize odours, you may choose to cover the floor drain with a wet cloth and place a flat, heavy object over the drain. If you are not able to put water down your floor drain (for example, if it is currently covered by flooring), we strongly recommend making it accessible before relining work begins to reduce the level of odours in your home.
Traffic and transit
We may need to temporarily close a single lane along Glen Erin Drive during some of our rehabilitation works. If we must reroute traffic, we will place signs giving directions. Transit stops will remain accessible.
Tree protection and trimming
Trees located in the municipal right-of-way will be protected during construction using temporary fencing. If tree branches within the municipal right-of-way interfere with construction, the trees will be pruned beforehand.
If tree branches on private property interfere with construction, they will be pruned back to the nearest suitable trunk or branch. The contractor will contact you before any pruning of private trees occurs. If you do not allow personnel onto your property to trim the tree, the branches will be cut vertically at the property line.
Repairing areas impacted by construction
We will start repairing any affected areas of the road, curb, sidewalk and lawns once we have finished our work on the sewer and maintenance holes.
Safety during construction
Construction zones require extra caution to keep everyone safe – pedestrians, cyclists, drivers, and construction workers. When driving, walking, or biking through the construction area, please be aware of your surroundings, watch for construction crews and other road users, slow down, account for delays, and consider other routes if possible. Learn more about how to stay safe in construction zones.
Keeping you informed
We will let you know if there are any major changes to the plans. Receive timely project updates right to your inbox by signing up for e-notices.
We value your feedback
After we have finished, we will invite you to provide feedback on the construction project.
You can sign up to receive this survey electronically.
Thank you for your patience as we complete this necessary work. This work will allow us to continue providing you with high quality wastewater services. If you have any questions, please contact us.
