System Flushing Program

Important Notice

Our system flushing program will be testing and cleaning the water mains and fire hydrants in neighbourhoods throughout the city on a predetermined basis starting in April and ending in October. The area targeted will be advertised in the Windsor Star before we begin.

If you live in the targeted testing and cleaning area, you may experience some mild colouring and sedimentation in your water while testing and cleaning is going on. This is NOT harmful and should clear up quickly, but please follow the guidelines below:


  • Fill some containers with water that you may need while the work is being done.
  • Laundry may be damaged due to discoloured water. Please avoid doing laundry until the Pipe Patrol has completed work in your neighbourhood.
  • Avoid running hot water taps because some discoloured water and sediment may be drawn into your hot water heater.
  • When the Pipe Patrol is finished working, and if you see discolouration, flow cold water through your inside faucets until the water is clear before drinking.
