Coleambally Wastewater Treatment Plant - New South Wales, Australia

Coleambally wastewater treatment plant is located on Kidman Way in Coleambally, within the Murrumbidgee Council area of New South Wales, Australia. The facility serves a small population of approximately 805 residents, reflecting the rural character of the region. As an operational plant, it plays a key role in managing local wastewater for this agricultural community. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. For a small agglomeration of this size, secondary treatment is appropriate under Australian water quality guidelines. The treated effluent likely enters local waterways that drain into the Murrumbidgee River, part of the Murray-Darling Basin, Australia's largest river system. This basin supports extensive agriculture and diverse aquatic ecosystems. The plant's operations are subject to New South Wales Environment Protection Authority regulations, ensuring discharge meets environmental standards to protect downstream water quality.

The plant's discharge likely flows into local creeks or irrigation channels that ultimately reach the Murrumbidgee River, a major tributary of the Murray River. The Murray-Darling Basin is a vital ecological and agricultural region, home to native fish species and wetlands. Even small plants like Coleambally contribute to the cumulative nutrient load, so secondary treatment helps protect downstream water quality and aquatic habitats.
