The Central Otago District Council strives to ensure that all of the district's fire hydrants are in good working order at all times. It would be unacceptable in the event that ANY part of our water system should fail to work at any time.
Flushing fire hydrants may, at first glance, seem like a waste of water, but there are a number of things taking place during this exercise. We hope an explanation helps to ease any concerns you may have.
Hydrant flushing removes the sediments from the mains and also serves the following purposes:
- Improves water quality in the distribution system;
- Verifies the proper operation of fire hydrants and valves;
- Helps find weaknesses in the water system;
- Checks for closed valves and weak flows in the water mains;
- Verifies adequate fire flows for firefighting.
Typically the Central Otago District Council will advertise the programme two weeks prior to starting. You can check out the following for notification when flushing will occur:
- Our website
- Local newspapers - particularly our CODC Noticeboard in the CO News
- Our CODC Facebook page
What should I do when water services staff are flushing in the area?
If you see water services staff flushing a hydrant on your street, avoid running tap water and using the washing machine or the dishwasher until the flushing is completed.
What could I expect before and after flushing?
