Dungog Wastewater Treatment Works Upgrade

The $28 million upgrade of the Dungog Wastewater Treatment Works (WWTW) is complete, with work now shifting to the nearby wastewater pumping station and connecting pipeline.

The upgrade is a significant investment in the Dungog area and will enable future population growth and have positive impacts on the environment.

Fast Facts

Location: Alison Road, Dungog

Investment Value: $28 million


The Dungog WWTW was commissioned in 1938 and we acquired the plant in 2008 from the Dungog Council.

Community benefits

The new Dungog WWTW uses modern technology and innovative design to enable improved reuse of recycled water and effluent, and improved water quality. We are continuing to work with our recycled water customer to get maximum benefit while reducing water releases to the Williams River.

We are now constructing a new wastewater pumping station on Windeyer Street Dungog and a new rising main pipeline to connect the pumping station and the new treatment works.

All efforts will be made to minimise disturbance to the local community, however there may be some changes to traffic and some increase in noise in the local area. Impacted community members will be advised before work starts.

Our lead contractor for this project is John Holland.
