Coonamble Wastewater Treatment Plant, New South Wales, Australia

Coonamble wastewater treatment plant is located in the town of Coonamble, New South Wales, Australia. The facility serves a population of around 2,652 and operates under secondary treatment standards, which is typical for small inland communities in Australia. The plant's treatment process involves secondary treatment, which includes biological processes to reduce organic matter and suspended solids. As a small-scale facility, it is designed to meet the environmental requirements set by the New South Wales Environment Protection Authority (EPA) under the Protection of the Environment Operations Act. The treated wastewater is discharged into the local environment, likely into the Castlereagh River or nearby waterways. The plant plays a crucial role in protecting the water quality of the region, which ultimately drains into the Murray-Darling Basin, a major river system supporting agriculture and ecosystems.

The plant discharges into the Castlereagh River, a tributary of the Macquarie River, which flows into the Darling River and eventually the Murray River. This system is part of the Murray-Darling Basin, Australia's largest river system, supporting diverse aquatic life and agricultural activities. The region experiences variable rainfall and drought conditions, making water quality management critical for downstream ecosystems and communities.
