The City’s annual watermain flushing program begins February 17, 2026. This 12-week program is essential for maintaining the City's water supply system and ensures the continued delivery of safe and reliable drinking water to residents and businesses.
Flushing generally takes place between 7am and 5pm, Monday through Friday (some exceptions may apply). Weekly updates on which parts of the overall watermain flushing zone are being flushed will be posted on this webpage.
What Is Flushing?
Flushing is an important part of the City’s ongoing maintenance program to ensure the integrity of the water supply system. It is a process that rapidly moves water through the piping system using water velocity to scour out materials that accumulate in the City’s pipes. During these times, residents and businesses may experience some discolouration of water and intermittent drops in water pressure. While some discolouration or sediment in the water may occur, it is a temporary condition and is not a health concern.
Steps To Take After Flushing
If your water is discoloured, follow these tips:
- If your water is discoloured or has sediment, run an indoor cold water tap until the water runs clear. This is usually 20–30 minutes but could take a few hours on rare occasions.
- Avoid doing laundry while your water is discoloured.
- Avoid using your hot water if the water is discoloured to prevent sediment from entering your water tank.
