Sanitary sewer replacement and improvement

Dartford Rd., Doncaster Dr., East Dr., Crescent Hill Dr. S., Railroad St., John St., Cornwall Rd., Lawrence Cr., Nanwood Dr., and Tullamore Rd. Project 19-2300E

The Region of Peel will be replacing the sanitary sewers along Railroad Street, Cornwall Road, Lawrence Avenue, East Drive, Dartford Road, Doncaster Drive, Crescent Hill Drive South, Railroad Street, John Street, Cornwall Road, Lawrence Crescent, Nanwood Drive, and Tullamore Road, as shown on these maps.

Sanitary sewers are underground pipes that carry wastewater from your home or business to a wastewater treatment plant. Wastewater is created when water goes down the drain or is flushed down the toilet. As pipes age and our population grows, we need to replace older sewers to keep providing you with high quality wastewater services.

Construction schedule

This construction work will be completed one street at a time, and will begin on Railroad Street in mid-August 2022. Later in 2022, construction will begin on Lawrence Crescent, Cornwall Road, and East Drive.

In 2023, we plan to begin construction on Dartford Road, Doncaster Drive, Crescent Hill Drive South, John Street, Nanwood Drive, and Tullamore Road. Residents on these streets will receive a notice before construction begins.

Once the underground work is completed on each street, we will begin repairing any driveways, boulevards, sod (grass), roads, curbs, and sidewalks impacted by our construction work.

We expect to complete this construction, including the associated repair work, by late 2023. These timelines are estimates, as weather and other unexpected events may impact our timelines.

This work will be under warranty for two years after the completion date.

Contractor and working hours

The work will be completed by Trisan Construction, and supported by Chisholm Fleming & Associates, 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.

Closed Circuit TV (CCTV) inspections

You may notice crews and large trucks in your neighbourhood doing CCTV inspections by taking videos of the inside of the sanitary sewers and storm sewers. This video footage lets us see the condition of the pipe before construction work begins. To record video inside the sanitary sewer, the wastewater may need to be removed from the sewer under the street, as well as the sanitary connection pipe that carries wastewater from your home to the sanitary sewer system. When this pipe is emptied, it may remove water from the P-trap inside your floor drains, sinks, bathtubs, and toilets. If this occurs, run some water down the drain, flush the affected toilets, and add water to any basement floor drains to ensure the P-trap(s) are refilled with water. This will prevent sewer gases from entering your home.

Traffic and parking

We may need to temporarily close roads or 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.

Areas impacted by construction

Replacing sanitary sewers usually requires digging a trench within the municipal right-of-way, 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 sanitary sewer, this trench might cause temporary damage to roads, curbs, sidewalks, boulevards, driveway aprons, and lawns within the municipal right-of-way.

The Region of Peel may also repair or replace the municipal portion of the sanitary sewer connection, the smaller underground pipe running from your business to the Regional sanitary sewer system. The sanitary sewer connection is often located very close to the water service. Replacing or repairing the sanitary sewer connection may require digging up either the lawn or driveway above this section of pipe and disturbing an area at least 2 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.

In-ground sprinkler systems

As the front lawn may be affected by this construction work, we strongly recommend moving any sprinkler lines that are located in the municipal right-of-way or next to the sidewalk. 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.

Repairing areas impacted by construction

We will start repairing the road, curb, sidewalk, driveways, and lawns once the new sanitary sewer is buried and work has been completed on all sanitary sewer connections on your street. Repairs may be delayed due to contractor availability or certain seasonal weather conditions.

For example:

• Paving cannot take place when the ground is saturated with water, or the temperature is below 3°C.
• Asphalt is not available in large volumes during the winter. Asphalt usually becomes available around mid-May.
• Most sod farms are located north of Peel. They usually have sod available beginning in late May. We will replace the sod on your property once it is available. We replace sod only until the middle of November, weather permitting, to let the sod grow roots. If we do not repair your lawn by the middle of November, we’ll replace the sod the following spring.

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

• Asphalt driveways: If we need to cut a section of your driveway, the driveway will be repaired by paving a stripe over the disturbed area, resulting in minimal seams in the final driveway. The Region of Peel cannot replace your entire driveway. If you would like to have the rest of your driveway paved, please contact the contractor, Trisan Construction, at (416) 410-3839. The contractor will then share contact information for the company hired to do the paving repairs. Please remember this is your option. If you decide to have your entire driveway repaved, this extra paving work is your responsibility and outside the jurisdiction of the Region of Peel.
• Interlock or concrete driveways: If we damaged a portion of your driveway, our contractor will reinstate the damaged portion of the driveway.

Driveway access

It may be necessary to block your driveway for a short time when crews are digging the trench for the sanitary sewer, working on your sanitary sewer connection, 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.

Vibrations

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.

We value your feedback

After we have finished, we will invite you to provide feedback on the construction project.
