Water Main Flushing Program

Water main flushing is an annual process to help maintain a City's water distribution pipe system.

The City's 2022 Uni-Directional Flushing program is scheduled to run from October 19 to November 30, 2022. Flushing operations will be carried out between 8 a.m. to 5 p.m., Monday through Friday, although this is subject to change.

What is flushing?

Flushing is a method of cleaning the water main pipes by forcing water through them at high speed and discharging it through hydrants, which are left open until the water runs clear. This fast-moving water flow scours and cleans out mineral deposits and sediment that have built up over time and settled at the bottom of the pipes.

Frequently Asked Questions

  1. Can you provide me with an exact date and time of flushing?

Unfortunately, we cannot. The water main flushing for each section of the pipeline can vary from five minutes to an hour and a half. When one section of the pipeline is completed, they will move on to the next section. 

City staff are working hard to minimize the disruption caused in your area, and due to the varied timeline of the work, it is difficult to schedule a specific time.
