Restrictions on the Westport/Carters Beach Water Supply have now been downgraded to ‘CONSERVATION’ water usage for all consumers. Conservation water usage is defined as a considerate use of water for all activities at all times, following Council’s water saving tips. Consumption and the reservoir level will continue to be monitored daily and Council will keep the community updated with trends. If capacity of the reservoir drops below 50% at any time, Essential Use restrictions will be reinstated for all consumers.

The following infographic has been produced to provide information to the public in regards to the Westport and Carters Beach Water Supply.
On this page you will also find the definitions for water restrictions in Buller along with water saving tips.

The first delivery of new pipe for installation to replace the existing pipe between the raw water reservoir and water treatment plant for the Westport and Carters Beach water supply arrived yesterday from Christchurch.

The 20 metre lengths will be stored adjacent to the water treatment plant until they are ready for installation. Further pipe deliveries, along with welder to join pipe sections, are expected to be onsite by the end of next week.

The existing reinforced concrete pipeline was originally installed over 80 years ago. The replacement pipe is made out of polyethylene and has an expected life of 85 years.

The total length of pipe to be replaced is 610 metres. This work is scheduled to be completed by the end of 2017.


Water restriction definitions

Essential Use

  • Water can be used for drinking, food preparation, hygiene and sanitary purposes only.
  • There is a complete ban on any outdoor water use.


  • Limited use of water for operational and maintenance priorities as required for business sustainability.
  • Limited residential outdoor use with hand-held buckets, watering cans, water blasters and low flow devices/attachments.
  • No high-use consumption/filling activites or general hard-surface hosing is permitted, including unattended sprinkler devices.


  • Considerate use of water for all activities, following Council’s water saving tips (below).
  • Conservation replaces ‘normal use’ for our current system.


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



Council appreciates residents’ patience and co-operation during this time.
