Coleraine Drive. Project 20-1177

The Region of Peel will be working along Coleraine Drive to install new watermains and rehabilitate the existing sanitary sewer system, as shown on the attached map.

Construction schedule

Construction is planned to begin February 2023 and be completed in the fall of 2023. These timelines are estimates, as weather and other unexpected events may impact our timelines.

All work is under warranty for two years from the completion date.

Contractor and working hours

The work will be completed by Clearway Construction Inc. and supported by GHD Limited, 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 your area to be under construction for a longer period of time.

Traffic and parking

Coleraine Drive will be closed to all through traffic during construction. The closure of Coleraine will be completed in two separate phases. Each phase is expected to take three or four months:

During the road closures, residents who live on the street will have access to their homes. Access to businesses will be maintained. No through traffic will be allowed and there will be no on-street parking. Traffic will be directed by police officers or a flag person. Emergency service vehicles and school buses will be permitted to cross through the closure with guidance from the onsite contractor.

We apologize for any delays or inconvenience resulting from these traffic impacts.

Interrupting your water supply

We anticipate that this construction project will require temporarily shutting off your water

For residents:

For businesses:

If we must shut off your water due to an emergency, we will knock on your door to alert you, and do everything we can to fix the problem as quickly as possible.

Wastewater service interruptions

When we reline the sanitary sewer, 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, Clearway Construction Inc. will provide you with notice at least 24 hours before the lining process begins.

It is important to minimize your water use during the service work:

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.

Areas impacted by construction

Installing the new watermain will require digging a trench within the municipal right-of-way, which includes the street and the land owned by the municipality between the water service box and the street. (The water service box is a small, round, metal valve located outside, on the property line between your house and the road.) Depending on the location of the watermain, this trench might cause temporary damage to roads, boulevards, driveway aprons, and lawns within the municipal right-of-way.

To maintain your water supply, the Region of Peel will also replace:

This requires digging up your water service box located in the lawn or driveway, and disturbing an area at least two square meters. Any damage caused by Regional construction will be repaired. We recommend you delay any driveway paving or major landscaping projects until this construction work is completed.

Tree trimming

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 the road, driveways, and lawns once the new watermain is buried and new water service lines have been connected to all properties on your street. Repairs may be delayed due to contractor availability or certain seasonal weather conditions.

Repairing grassy areas

The contractor will replace any damaged sod (grass) on the boulevard or your front lawn and will take care of the new sod for 30 days. You can help the sod stay healthy by watering it. A longer ‘deep root watering’ works better to establish new sod than watering more frequently for a shorter time. Watering in the early morning allows more water to soak in instead of evaporating.

Repairing driveways

Driveway access

It may be necessary to block your driveway for a short time when crews are digging the trench for the watermain, replacing your water service box and pipe, relining the sanitary sewer, working on the sewer maintenance holes, or completing other construction activities. If so, we will knock on your door to notify you. If a trench prevents access to your driveway, the contractor will have metal road plates available to allow access if required. Whenever possible, we will work to ensure businesses can be accessed. Please contact us if you have special needs related to access.


You may smell some?odours from the sewer relining work 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. 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. At least 24 hours before the sewer next to your property is relined, Peel Region’s contractor will provide you with a notice advising you of the exact date and time of this relining work.

Waste collection

If you receive waste collection from the Region of Peel, your garbage, recycling, and organics will continue to be picked up on your regularly scheduled day. It is the contractor’s responsibility to move your garbage, recycling, and organics bins from the end of your driveway to a location where waste collection vehicles can pick them up. Empty containers will be returned to their corresponding addresses. Please make sure your house number is clearly marked on each bin. This helps us return empty bins to the correct address.


You could feel slight vibrations from the construction work.

Optional protection plans for your exterior water pipes, wastewater pipes, and in-home plumbing

Many homeowners are not aware that they are responsible for maintaining the water and wastewater pipes both inside their home and outdoors up to the property line. If one of these pipes breaks, it can cause unexpected and costly repairs. The Region of Peel has partnered with Service Line Warranties of Canada (SLWC) to offer homeowners optional, affordable protection from unexpected home repairs.

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. To learn more about how to stay safe in construction zones, visit

Keeping you informed

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