Sanitary sewer maintenance hole rehabilitation

Various streets. Project # 22-2307.

Peel Region will be working to rehabilitate or replace aging maintenance holes (commonly called manholes) in various locations across Peel. This work will ensure the sanitary sewer system can continue to be accessed and maintained from the manholes. 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.

The majority of our work will involve repairing maintenance holes. When we need to fully or partially replace the maintenance hole, we will share additional information with affected residents and businesses before the work begins.

Construction schedule

This work is planned to begin August 18, 2023, and be completed in the middle of 2024. During this time, we will be rehabilitating or replacing approximately 63 maintenance holes. It typically takes a few hours to three days to repair a single maintenance hole, depending on the work required. When the maintenance hole needs to be completely replaced, this work may take a couple of weeks.

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

Contractor and working hours

The work will be completed by Michels Canada Co. and supported by Andrews.Engineer, 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 your area to be under construction for a longer period of time.

Traffic and parking

We may need to temporarily reduce traffic to a single lane during construction. If we must reroute traffic, we will place signs giving directions. On-street parking will be reduced during construction when we are actively working on your street.

Driveway access

It may be necessary to block your driveway for a short time when crews are working on the maintenance hole or repairing the resulting damage to the road. If so, we will knock on your door to notify you. Whenever possible, we will work to ensure businesses can be accessed. Please contact us if you have special needs related to access.

Areas impacted by construction

Repairing maintenance holes often requires digging around the existing maintenance holes to install new parts. These maintenance holes are usually located within the municipal right-of-way, which includes the street and the land owned by the municipality between the street and your water service box. (The water service box is a small, round, metal valve located outside, on the property line between your house and the road.) If maintenance holes are not within the right-of-way, Peel Region has obtained legal access through easements.

Depending on the location of the maintenance hole, this work may cause temporary damage to roads, curbs, sidewalks, boulevards, driveway aprons, and lawns within the municipal right-of-way or easement. Any damage caused by Regional construction will be repaired.

In-ground sprinkler systems

If the construction inspector notifies you that your front lawn may be affected by this construction work (and you have an in-ground sprinkler system), we strongly recommend moving any sprinkler lines that are located in the municipal right-of-way or within one metre of the maintenance hole. If you can’t relocate these sprinkler lines, please send us a map created by your irrigation contractor or flag each sprinkler head that is located within one meter of the sidewalk, curb, or driveway. This will allow us to minimize the impact to your sprinkler system.

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. If you do not allow personnel onto your property to trim the tree, the branches will be cut vertically at the property line.

In Mississauga, trees located in the municipal right-of-way will be protected during construction using temporary fencing.

Repairing areas impacted by construction

We will start repairing any affected areas of the road, curb, sidewalk, driveways, and lawns once we have rehabilitated or replaced the maintenance holes. Repairs may be delayed due to contractor availability or certain seasonal weather conditions.

For example:

Repairing grassy areas

If this construction work impacts the boulevard or your lawn, the contractor will replace any damaged sod (grass) 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

If the construction inspector notifies you that your driveway may be affected by this construction work, all damage caused by Regional construction will be repaired.

Waste collection

If you receive waste collection from Peel Region, and our construction work is happening in front of your home during your waste collection 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.

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.

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.
