Water mains flushing

Waitomo District Council ensures that our district's water reticulation schemes are in good working condition.

Mains flushing, hydrant flushing and valve maintenance are essential elements of our routine maintenance programme and provide the following benefits:

  • Removes sediments in water supply mains and improves water quality;
  • Ensures fire hydrants and valves are operating properly;
  • Helps identify weaknesses in the water reticulation system;
  • Checks for closed valves that may contribute to weak flows and pressures in the system.

WDC undertakes routine hydrant flushing on a monthly cycle around the urban areas.  The process involves aggressively releasing water through the pipes which may cause discolouration of tap water in some areas.  

Hydrant flushing is carried out during the third week of every month or as required. The list of streets is advertised in the Waitomo News and on our website.

We make every effort to minimise the impact on supply. In the event that temporary deterioration of your water quality occurs due to flushing in your street, it is advisable to first run your garden tap then the others for several minutes to remove any air bubbles and to restore water clarity.  Please do not run water through in house filters before taps are running clear.
