Water treatment plants

Council water treatment plant

Council supplies high quality drinking water for the Tweed, helping protect the health of our community.

We sustainably operate and maintain 3 water treatment plants, delivering 9600 mega litres of drinking water each year in ways that minimise our impact on the environment.

Bray Park water treatment plant

The $76 million Bray Park Water Treatment Plant is one of the most advanced water treatment plants in Australia.

Treatment processes at the plant are designed to meet or exceed the requirements of the Australian Drinking Water Guidelines.

  • Location: Durroon Avenue, Bray Park (Murwillumbah)
  • Services: main water treatment facility for the Tweed
  • Capacity: up to 150 megalitres per day


The immersed membrane ultra-filtration facility features the latest membrane technology, providing a much higher level of filtration. ZeeWeed membranes remove greater than 99.99 per cent of suspended solids, bacteria and parasites (Cryptosporidium and Giardia) and greater than 99% of particle-bonded viruses.


The plant was designed by Hunter Water Australia, constructed by the Reeds Group and project managed by NSW Public Works and Tweed Shire Council. Work began in November 2007 and took two years and six months to complete, with the plant being commissioned in April 2010.

Tyalgum water treatment plant

The Tyalgum Water Treatment Plant delivers very high quality potable water which meets the Australian Drinking Water Guidelines.

  • Location: Carraboi Terrace, Tyalgum
  • Services: Tyalgum
  • Capacity: up to 250 kilolitres per day


Following a major upgrade in 2012, the plant features the same membrane filtration technology as the state-of-the-art Bray Park Water Treatment Plant.


In 2012, the Tyalgum Water Treatment Plant underwent a major $1.65 million upgrade. The existing plant needed upgrading as it included a coarse in-creek filtration and chlorination system which was not able to adequately treat water during periods of poor raw water quality, such as after heavy rain or a long dry spell. It is now less likely that water will need to be carted to the village when the raw water quality is poor.

Uki water treatment plant

  • Services: aroundt 170 households in Uki and adjacent rural areas
  • Capacity: 0.44 megalitres per day


Raw water from the Tweed River is pumped to the Uki Water Treatment Plant where it is treated to remove sediments and kill bacteria and viruses.

The treatment process comprises pH correction, chemical precipitation, clarification in a Lamella Separator, filtration in a Dynasand filter and disinfection.

Water testing


The Tweed Laboratory Centre and the operational staff at the water treatment plants routinely sample and analyse water taken from throughout the reticulation system of the town water supply.

Results are measured against the Australian Water Drinking Guidelines and provided to the NSW Department of Health.

There are a number of chemicals that need to be tested for before water is deemed safe to drink. This includes heavy metals, some nutrients and potentially pesticides and other organic compounds where there is a risk of possible contamination from these.
