Sanitary sewer relining project

Main Street North, Clark Boulevard. Project 21-2300D

The Region of Peel will be working in your neighbourhood to rehabilitate the existing sanitary sewer system on Ambler Drive and Jayson Court. Sanitary sewers are underground pipes that carry wastewater from your home to a wastewater treatment plant. Wastewater is created when water is flushed down the toilet, or goes down the drain in your sink, tub, or shower.

To extend the service life of the sewer under your street, Peel Region’s contractors will clean the existing sewer pipe and place a new resin (plastic) lining within it. This work will be completed underground with specialized equipment, and will not require digging trenches in your neighbourhood.

Construction schedule

We expect to conduct this work in your neighbourhood from February 6 to February 10, 2023.

Contractor and working hours

The work will be completed by Services Infraspec Inc and supported by Andrews Engineer, both under contract to the Region of Peel. 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.

Wastewater service interruptions

To complete this work, your wastewater service pipe will be out of service (plugged) for approximately 8 hours. (Wastewater service pipes carry wastewater from your home to the underground sanitary sewer system.) This temporary service interruption allows for the pipe to be repaired without digging up the street. To advise you of the exact date and time of this service interruption, Infraspec will provide you with a second notice at least 24 hours before the lining process begins.

It is important to minimize your water use while this sewer work is underway:

These actions will reduce the possibility of wastewater (also known as sewage) backing up into your basement or into your plumbing. If you have a sump pump, please notify us at or tell the contractor when they arrive at your property.


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, either the evening before or day of the relining work. 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 parking impacts

The work will be phased to minimize disruption to traffic. At least one lane will be open in each direction during this work. On-street parking will be reduced when we are actively working on your street.

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.

Keeping you informed

We will let you know if there are any major changes to the plans.

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.
