Watermain and Sanitary Sewer Replacement and Improvement

Mill Street South Project 18-1380

The new watermain and sanitary sewer on Main Street South has now been installed. The next phase is to bring the new watermain and sanitary sewer into service. Properties on these streets will now have their individual water service and sanitary service pipes transferred from the old watermain and sanitary sewer to the new watermain and sanitary sewer.

Water Service Transfer

A new water service pipe will be installed from the watermain to your property line, where a new water service box will also be installed. The water service box is a small round metal valve typically located in your driveway or lawn at the front of your property. Replacing your water service box requires digging up your existing water service box and disturbing an area at least two square meters.

Where possible, your water service pipe will be installed using tunneling equipment. If tunnelling isn’t possible due to ground or environmental conditions, the contractor will need to dig a trench to install the new pipe.

Any damage caused by Regional construction will be repaired:

Interrupting your water supply

Connecting your property to the new watermain 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.

Sanitary Service Transfer

The Region of Peel has also been working in your area to replace the existing sanitary sewer system on Main Street South. Sanitary sewers are underground pipes that carry wastewater from your neighbourhood 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.

A new sanitary sewer has now been installed on Main Street South. The next phase is to replace existing wastewater service pipes from the property line to the new sanitary sewer main. The wastewater service pipe carries wastewater from your home or business to the Regional sanitary sewer system. We typically only replace or reline the portion of the pipe within the Regional right-of-way leading from the property line to the new sanitary sewer, as it is the property owner’s responsibility to maintain the portion of pipe on your private property.

The contractor will need to dig a trench to install the new wastewater service pipe. If obstructions like trees or utilities prevent the replacement of the wastewater service pipe, we may need to reline the pipe instead of replacing it. To access the wastewater service pipe for cleaning and relining, we may need to dig a hole approximately two metres by two metres in size, close to your front property line.


We expect to start connecting water service pipes to the new watermain and replacing the wastewater service pipes on Main Street South as early as Wednesday, July 12, 2023. We expect to complete this work by August 11, 2023. Once we have connected properties to the new watermain and sanitary sewer, we will start repairing driveways, roads, curbs, sidewalks, and sod (grass).

Please note that repairs may be delayed due to contractor availability or weather conditions.
For example:

Repair work completed as part of this watermain replacement project is under warranty for two years from the completion date.

Driveway repairs

Contractor and working hours

The work will be completed by CRCE Construction 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 neighbourhood to be under construction for a longer period of time.

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.
