Our Water Treatment Plants

Shoalhaven Water supply clean and dependable water to our residents and visitors, and we operate every day of the year.  

Water Treatment Plant

We own and operate 4 water treatments plants where we can ensure your water quality is enhanced by:

  • The removal of sediments, colour and iron oxides,
  • Improvement of water hardness to protect the pipelines, and
  • The addition of fluoride and chlorine for the protection of public health.

Our Water Treatment Plants

Bamarang Water Treatment Plant

Commissioned in 1982, the Bamarang Water Treatment Plant was purpose built to provide ongoing provision of water to the growing population of the Shoalhaven. It is our main water treatment facility and can process up to 75 million litres of water each day.  

The water treated at this facility comes from the Shoalhaven River where it is pumped from Burrier to an off-stream storage dam adjacent to the Bamarang WTP. After treatment, the water is pumped to 38 reservoirs across the Shoalhaven between Berry and Burrill Lake.


Flatrock Water Treatment Plant

First commissioned in the 1930’s, the Flatrock Water Treatment Plant was the Shoalhaven’s first water treatment facility and it provided water for around 750 people. Flatrock was upgraded in 1970 and then again in 1998 and is still used today to provide water to the urban areas of Nowra, Bomaderry and Terara. It also supplies water to the Manildra factory. 

Flatrock Water Treatment Plant processes up to 28 million litres of water each day.  


Milton Water Treatment Plant

Commissioned in 1998, the Milton Water Treatment Plant is the southern Shoalhaven water supply providing filtered water to the residents of Milton, Ulladulla, Narrawallee, Kings Point, Burrill Lake and Tabourie Lake. This water treatment facility processes around 10.5 million litres of water each day.  

Water gravitates from Porters Creek Dam through a dual pipeline system to the Pointer Mountain balance tank and then passes to the Milton Water Treatment Plant where it undergoes filtration and treatment. Water from the treatment plant passes into Milton reservoir and then gravitates to Narrawallee, North Ulladulla, West Ulladulla and Burrill Lake reservoirs on demand.

The distribution system extends south from Burrill Lake reservoir with a pipeline to Tabourie Lake.


Kangaroo Valley Water Treatment Plant

Commissioned in 1993, the Kangaroo Valley Water Treatment Plant uses a microfiltration system to improve water quality. The membrane technology eliminates the need to add chemicals as used in traditional treatment processes. 

The facility was upgraded in 2019 to include an additional membrane which acts as a backup system should a failure occur. 

This water treatment facility processes up to 1.5 million litres of water each day and is distributed to the residents and businesses within the valley.
