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 will be building the new wastewater treatment work at the existing Hunter Water site on Alison Road. We are currently investigating building a new wastewater pumping station (WWPS) on Windeyer Street, Dungog and a new pipeline connecting the pumping station and the treatment works.

Key Dates

Work is expected to start at the WWTW in September 2019 and be completed by March 2021, weather permitting.  All efforts will be made to minimise the disturbance to the local community, however there may be some changes to traffic and some increase in noise in the local area.  All impacted community members will be advised before work starts.
