Buller District Council

Reefton Water Supply


The precautionary boil water notice remains in place for consumers on the Reefton water supply. Further advice and answers to frequently asked questions regarding the boil water notices are available below. This information includes guidance on how long to boil water to ensure safe consumption.

Council’s contractor has completed the preparation and sanitation of the additional secure water tanks. These are the five 30,000 litre tanks located next to the reservoir.  The supply is now running into these additional reservoir tanks.  This allows for the draining of the main reservoir so a full inspection can be carried out.  Once the main reservoir is drained it will be cleaned and disinfected.

Ongoing testing is being carried out within the water supply network.  These results have been clear.  Council continues to collaborate with the Canterbury District Health Board (DHB), and is awaiting advice from the DHB whether it is necessary to keep the precautionary boil water notice in place.

Council is working with best practice industry advice on planning the improvements to both the infrastructure layout and potential changes in treatment processes.  This is to ensure the best medium and long-term performance for the supply.  Council is committed to ensuring regulatory compliance is achieved and to provide clean, safe and reliable drinking water.

Council appreciates the understanding and cooperation of the Reefton community during this time.

Water saving tips


  • Rinse or peel vegetables in a bowl or sink filled with water instead of running the tap – you could save up to 10 litres every minute
  • Wait until you have a full load before starting your dishwasher. When possible, use the eco-setting
  • Rinse dishes in a sink filled with water, rather than under a running tap
  • Keep a jug of drinking water in the refrigerator instead of running the tap water until cold


  • Turn off the tap when cleaning your teeth or shaving – you could save 10 litres of water a minute. Brush your teeth in the shower.
  • Reduce your shower time to three minutes or less
  • Keep baths to a minimum
  • Every time you flush the toilet you use 13–20 litres of water, so make sure you only flush when you need to. Or use a half-flush if your toilet is fitted with one.


  • Wait until you have a full load before starting your washing machine or use the partial load settings


  • Save water by only watering the garden when it needs it. Use only a hand held hose rather than a sprinkler
  • Water at cooler, less windy times of the day, in the morning or evening, to minimise evaporation and water wastage


  • Do not hose down paths and driveways; use a broom instead
