Kurri Kurri WWTW Upgrade



The Kurri Kurri Wastewater Treatment Works Upgrade (WWTW) will increase the capacity of the existing Kurri Kurri WWTW.

Hunter Water is continually improving water and waste water services and this significant investment in the Kurri Kurri area will support future population growth. The last upgrade of this site was in 2011.

About the project

Kurri Kurri WWTW is undergoing an upgrade that will cater for a population growth of up to 25,000 community members. The upgrade will also help protect and improve the health of our environment and waterways, avoiding negative social and environmental impacts. 

A new wastewater clarifier will be built to increase capacity and improve water quality. New electrical equipment is being installed to improve safety and efficiency.

The work will be done by Hunter Water's principle contractor, John Holland.


Kurri Kurri WWTW is adjacent to the busy Hunter Expressway, and is surrounded by bushland. The entry is via McLeod Road, Kurri Kurri. Work will be fully within the boundaries of the existing WWTW site. 

Key Dates

Work will start in September 2019 and the project is expected to be finished in mid 2020, weather depending.
