Dungog Wastewater Treatment Works Upgrade


A $28 million upgrade of the Dungog Wastewater Treatment Works (WWTW) has started with the appointment of the construction contractor, John Holland. 

The upgrade is a significant investment in the Dungog area and will enable future population growth in Dungog and will improve our environment.

About the project

The new Dungog WWTW will use modern technology and innovative design, replacing the almost 90 year old system. 

The new work will improve water quality released from the plant. The improved water quality will enable increased use of the recycled water which will reduce the need for water to be released into the Williams River.

We are also investigating building a new wastewater pumping station (WWPS) on Windeyer Street, Dungog, and a new pipeline connecting the pumping station and the treatment works.

The project is not expected to be particularly noisy other than for short periods. Residents may notice some more traffic movements on Alison Road. 

Night works may occur between 10 February and 27 March 2020. At this time lights may be seen and there will be some additional noise and activity at the site.  We will work to minimize any impacts on the community. We will contact any neighbours that may be impacted.


The new wastewater treatment work is at the existing Hunter Water site on Alison Road.
