Drinking water

Council manages water supplies to support the health and well-being of the community.

Water is an essential need for individuals and commercial operations. Council provides sufficient quantities of potable water for domestic and commercial needs and public amenities. Council water management is required under a number of legal statutes.

Westport and Carters Beach 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 pipes. 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 sediment and bacteria removal, treated with lime for pH adjustment, UV for protozoa removal and chlorination for additional treatment of bacteria and viruses.

Reefton water supply

The Reefton Water Supply is sourced from an infiltration gallery located adjacent to the Inangahua River near The Strand. The infiltration gallery collects groundwater that has naturally filtered through river gravels before entering the water supply system.

The water is filtered to remove suspended particles, treated with UV for protozoa removal, chlorinated for protection against bacteria and viruses, and adjusted for pH to improve water quality and stability. Treated water is then pumped to a reservoir above the township before being distributed to consumers.

Punakaiki water supply

The Punakaiki water supply provides drinking water to the Punakaiki township and Ross Subdivision. Water is sourced from a catchment north of the township and conveyed to the treatment plant before distribution to consumers.

The water is filtered using Macrolite media, treated with UV for protozoa removal, chlorinated for protection against bacteria and viruses, and adjusted for pH to improve water quality and stability. Treated water is stored in a series of reservoirs before being distributed throughout the supply area.

Inangahua Junction water supply

The Inangahua Junction water supply is sourced from a shallow bore that collects naturally filtered groundwater from the surrounding river gravels. Water is pumped from the bore and treated before being supplied to the township.

The water is treated using calcite filtration for pH correction and UV disinfection for protection against microbiological contaminants. Treated water is then stored in a reservoir located in the hills southeast of the township before distribution to consumers.

Plumbosolvency

Drinking water is capable of dissolving very small levels of heavy metals such as lead and copper out of some household plumbing and fittings. This is means the water is plumbosolvent.

This applies to all households in New Zealand, including those on public and private water supplies in the Buller district.

The Ministry of Health has urged Councils to make residents aware that some plumbing fittings have the potential to allow minute trace 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.

Metered water supplies

Some rural or commercial properties metered water connections from Council operated water supplies. At the point of connection, Council installs a water meter to track water usage. The meter is read regularly, and Council aim to complete this monthly. Read our FAQs to find out more.

As a rural householder, you are charged an annual water rate with an allowance of 400 cubic meters (400,000 litres) per year. High volume users can opt to pay more than one water rate – to spread the cost across the financial year.

As our rating year starts on 1 July, a reading is taken on 30 June. Each month, we compare actual usage, to date, against this reading. If your usage passes 400 cubic meters, Council will issue an invoice, each month, until 30 June – when the calculations against your annual allowance start again.

Most rural connections have been self-installed. Council did not install the connection and, as it sits within a private property, Council has little control over what type of pipes have been used, whether they’re protected from damage, or if they leak.

Rural connections are much more prone to breaking or leaking and, as the pipe distances are often long or obscured from view, large leaks often go undetected. A higher meter reading is an alert that something has changed or there could be a problem.

Rural connections are also often used for stock watering. Water troughs are notorious for leaking via faulty valves or damage to the trough itself. Cattle are also known to unintentionally damage feeder lines.

 

Council has bylaws in place that specifically mention water leaks for all property types.

All water users are required to report and attend to water leaks and are liable for penalties for wasting water. Rural connections, just like town connections, are responsible for the plumbing starting at the Council water supply valve.

Council recommends that rural property owners make themselves familiar with where their water lines are placed and undertake regular inspections (preferably weekly, but at least monthly) to check for leaks.

If you notice a change in water pressure, or a patch of ground is always wet: these may be signs you have a water leak.

Council recommends property owners engage a qualified plumber to undertake any work on your supply lines or internal plumbing. It will be the property owner’s responsibility to pay for any repairs past the water meter.

Council will repair any leaks or damage up to, and including, the water meter. 

Council understand that sometimes mistakes happen, numbers get transposed, and meters can develop faults.

If you think your reading is incorrect or, if you’re sure you don’t have leaks, we can arrange for the meter to be re-read, replaced or monitored with a check meter. If Council finds a fault on Council's water meter equipment, you will be credited any excess payment that you have incurred.
