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 spring and ending in fall.

During this time, ENWIN’s schedule for upcoming areas of hydrant flushing will be advertised every Saturday in the Windsor Star. For daily information about where we are working, customers can follow ENWIN on our Twitter feed, @ENWINUtilities, or see the Hydrant System Flushing Map available on ENWIN's website.

Customers located in the targeted flushing areas may notice some mild discolouration and sedimentation while the flushing is taking place. ENWIN assures customers that this is NOT harmful and should clear up after running their water tap for several minutes.

ENWIN recommends that customers follow the guidelines listed below, when system flushing is underway in their area:

  • Fill some containers with water you may require during the duration of the work.
  • Laundry may be damaged due to discolouration of the water. Please avoid doing laundry until the flushing has completed work in your neighbourhood for that day.
  • Try not to run any hot water taps, as some discoloured water and sediment may be drawn into your hot water heater.
  • When the system flushing is finished and you notice discolouration, flow cold water through your interior faucets until the water is clear.

Any homeowner who continues to see discolouration in their water 24 hours after flushing has completed should call ENWIN at 519-255-2727. Customers with additional questions regarding the flushing operations can contact ENWIN at
