Background 

The City will be rehabilitating the watermain on Pitt Street, from Cornwall Centre Road to McKenzie Street. There are two existing watermains along this stretch of Pitt Street, one is a 500mm diameter concrete pressure pipe installed in 1974 and one is a 200mm diameter PVC pressure pipe installed in 1997. The City is planning to line the 500mm diameter concrete pressure pipe in 2024.

The rehabilitation process is called cured-in-place watermain lining. The process consists of inserting a flexible liner into the existing watermain. Once the liner is in place, steam is used to 'cure' or harden the liner. The process creates a new watermain inside of the existing one.

What to Expect During Construction

1. Installation of a temporary watermain in the boulevard
2. Installation of temporary water services from the watermain to your outdoor taps.
3. Connecting residences to the temporary water supply.
4. Excavation of access pits at intersections and strategic locations.
5. Cleaning the existing watermain.
6. Inspecting the watermain using closed circuit television (CCTV) devices.
7. Installing the new liner.
8. Cutting holes in the liner in locations where there are residential water services.
9. Disconnecting residences from the temporary water supply.
10. Removing the temporary watermain and services.
11. Restoration (New Topsoil & Sod and Repairing Driveways, Roadway, and Curb).

Residents should expect to see access pits at the following locations:

• Pitt St at Cornwall Centre Rd (Northeast quadrants of the intersection)
• Pitt St at Cariere Av (North quadrants of the intersection)
• Pitt St at Mercier Av W (Northwest quadrants of the intersection)
• Pitt at McKenzie St (Northeast quadrants of the intersection)

You can expect that there will be times when the water supply is disrupted. This is because the water must be off in order to connect/disconnect residents to the temporary water supply. The Contractor will send out notices in advance of the water being turned off.

Sometimes, unexpected events happen, like watermain breaks. When that happens, we are unable to provide notice. We will work to restore your water service as quickly as possible.

There may be days where you don't see the Contractor on site between the different stages of work. This is a normal part of the process. The Contractor has many crews that do different types of work.
