2022 Catherine Watermain Lining Map


The City will be rehabilitating the watermain on Catherine Street, from Riverdale Avenue to the East Limits. The existing watermain is made of 150mm diameter cast iron and was installed in 1964-1968.

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:

  • Catherine St (Eastern limit)
  • Catherine St and Riverdale Ave (North and South West quadrants of the intersection)

There will be times when the water supply is disrupted. This is because the water has to be off in order to connect/disconnect residents to the temporary water supply. The Contactor will send out notices in advance of the water being turned off.

Sometimes, unexpected events happen, like watermain breaks. When that happens, we cannot 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.

If you have any concerns, give us a call or e-mail us using the contact information on this page.

  • Close your outside garden tap by turning the tap clockwise.
  • Turn on your main waterline supply valve (usually located in the basement towards front of the house).
