  • Hensall-Zurich Distribution System (Zurich) – April 13th to 24th
  • Bluewater Distribution System (Lakeshore) – April 27th – May 15th
  • Bluewater Distribution System (Bayfield) – May 18th – June 5th

The Varna distribution system will be flushed on the following dates:

  • March 19
  • May 21
  • June 18
  • July 16
  • August 20
  • September 17
  • October 15

You may experience discoloured water coming from your tap. If this happens, we suggest you try the following:

  • Remove the tap aerators from your taps and flush the cold water house line until it runs clear.
  • Flush out your hot water tanks. This is to remove the accumulated iron that precipitates out in the tank; this iron may also decrease the efficiency of your water tank.

You may experience fluctuating water pressure due to the flushing activities.
