Water Main Flushing

watermain flushing, water from pipe pouring into man hole.

Water main flushing is an annual process that takes place in October to help maintain a City's water distribution pipe system. Water mains are underground pipes that carry water from the water reservoir to your street.

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

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.
