All biosolids produced at the Cessnock Wastewater Treatment Works (WWTW) are beneficially used for mine site rehabilitation.
Recycled water is used for:
- grit and screening washing
- general wash down around the WWTW
- ground irrigation.
A nearby farmer and golf course also take up to 50 megalitres per year of recycled water from the Cessnock WWTW for irrigation.
The rest of the effluent is discharged to Black Creek. Downstream irrigators are also licensed to extract water from Black Creek, the flows of which are mainly sustained by treated effluent from Cessnock WWTW.
Hunter Water recycles approximately 5091 megalitres per year. Learn more about our recycling and reuse initiatives.
