Murrurundi Wastewater Treatment Plant | New South Wales, Australia

Murrurundi wastewater treatment plant is located in the Upper Hunter Shire Council area of New South Wales, Australia, along the New England Highway. It serves the small rural town of Murrurundi, with a population of about 1,364 residents. The plant is operational and provides secondary treatment, which is appropriate for a community of this size under Australian regulatory standards. The plant operates under the regulatory framework of the New South Wales Environment Protection Authority (EPA), which issues environment protection licences for wastewater discharges. For small inland plants like Murrurundi, secondary treatment is typically required to protect receiving water quality. The plant discharges approximately 352.88 megalitres of treated wastewater per year. The treated effluent from the plant is discharged into the local catchment, which ultimately drains into the Hunter River system. The Hunter River flows southeast to the Tasman Sea near Newcastle. The plant plays a key role in protecting the water quality of the Hunter River and its tributaries, supporting aquatic ecosystems and downstream water uses.

The plant discharges into the Hunter River catchment, a major river system in New South Wales that flows to the Tasman Sea. The Hunter River supports diverse aquatic life and is used for irrigation, recreation, and as a water source for downstream communities. The plant's secondary treatment helps reduce nutrient and organic loads, protecting the river's ecological health.
