How it works

The plant is designed to remove nutrients (nitrogen & phosphorus) and to provide a high level of disinfection.

The plant provides tertiary treatment of the wastewater by the following process:

• Inlet works including screening and grit removal
• Extended aeration activated sludge (carousel tank)
• two secondary clarifiers
• Chemical dosing to remove phosphorus
• two Sludge lagoons which are periodically emptied/dewatered
• two maturation (tertiary) ponds.

How is the treated effluent used?

The treated effluent is:

• used by a nearby farmer, or
• discharged to Fishery Creek which flows into Wallis Creek and then eventually into the Hunter River.

All biosolids produced at the plant are beneficially used for mine site rehabilitation and pasture improvement projects.
