Buller District Council


The Buller District Council maintains and operates domestic water supplies at Little Wanganui Subdivision, Mokihinui, Ngakawau/Hector, South Granity, Waimangaroa, Westport/Carters Beach, Reefton, Inangahua Junction and Punakaiki.

A Rural Water Supply sourced from Omanu Creek provides stock water for the farming community at Cape Foulwind.

Council’s role as water supplier to the region involves operating 3 water treatment plants and 2 pumping stations.

Westport Water Supply

The Westport Water Supply is from a creek catchment in the hills behind Westport and is transferred to the reservoirs by a series of underground tunnels and water races. These tunnels combined, are over 1,900 metres in length and were constructed around 1903, which in those days was a remarkable feat. The water is then coagulated for colour removal, treated with lime for Ph adjustment and chlorinated.

Westport residents use about five million litres of water per day.

The Westport/Carters Beach Water Supply is now on ‘ESSENTIAL USE ONLY’ water restrictions. This means that water use is restricted to drinking water, water used for cooking and water used for sanitation purposes (ie: showering, toilets, basic hygiene, laundry) only. There is a complete ban on outdoor water use which includes car/truck washing and garden irrigation. All other high use water activities are strictly prohibited. This applies to businesses as well as households.  Please click here for more information.

Reefton Water Supply

The Reefton Water Supply is pumped from an infiltration gallery adjacent to the Inangahua River, it is the filtered by macrolite media filters and further filtered through cartridge filters. Once filtered, it is then exposed to U.V. lights which disinfects the water, making it safe to drink.

Punakaiki Water Supply

The Punakaiki Water Supply is drawn from a creek in the hills and is filtered and sterilised by ultra violet light.

Plumbsolvency Warning

The Ministry of Health has urged Councils to make residents aware that some plumbing fittings have the potential to allow minute traces metals to accumulate in water standing in the fittings for several hours.

Although the health risk is small, the Ministry of Health recommends that you flush a mugful of water from your drinking water tap each morning before use to remove any metals that may have corroded from the plumbing fittings.

The Ministry of Health recommends this simple precaution to all households, including those on public and private water supplies.

Conserving water

Water is essential for many processes in life; a human can survive for only a few days without consuming water. Apart from drinking, we use water in many other ways such as washing clothes, dishes and ourselves.

Water is a valuable resource and demands on its usage are always increasing. Even in places renowned for rain (like the West Coast) it is important that we don’t unnecessarily waste water. Below are a few water conservation hints that can help to save water.

Economise – Be aware of the amount of water you use, and look for ways to use less. For instance, don’t leave the water running when you wash, shave and brush your teeth.

Maintenance – A leaking tap can waste more than 350 litres of water each day. Check your taps and replace worn washers or valve seats as needed. Use low flow shower heads, aerators or flow restrictors. For older toilets, install a toilet dam or displacement device such as a brick or large stone.

Save outdoors – Water your lawn or gardens only when it needs it. Landscape with trees and shrubs that require less water. If you use a sprinkler, make sure it is aimed correctly at your garden and that you are not watering your footpath!
