The City’s annual watermain flushing program begins February 18, 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 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 flushing, residents and businesses may experience some discolouration of water and intermittent drops in water pressure. It's temporary and not a health concern.
- Clear the water by running an indoor cold water tap for 20-30 minutes after the flushing period. Avoid doing laundry and using hot water if your water is affected.
- Flushing generally takes place between 7am and 5pm, Monday through Friday (some exceptions may apply).
- Watermain flushing will only take place in the 2026 Watermain Flushing Zone. Weekly updates on which parts of the overall watermain flushing zone are being flushed will be posted on this webpage.
