Millmerran wastewater treatment plant is located on Millmerran Cecil Plains Road in Millmerran, Queensland, Australia. It serves a small community of approximately 1,694 residents and operates under the regulatory framework of the Australian government, which mandates secondary treatment for inland plants to protect water quality. The plant provides secondary treatment, a standard level for small agglomerations in Australia. It discharges 438.29 megaliters of treated wastewater annually. As an inland facility, it does not directly impact coastal environments. The treated effluent is released into local waterways that drain into the Condamine River catchment, part of the Murray-Darling Basin. This basin supports diverse aquatic life and is an important agricultural and ecological region in eastern Australia.

The plant discharges into local waterways that flow into the Condamine River, a tributary of the Murray-Darling Basin. This basin is a vital ecological and agricultural region, supporting diverse aquatic species and migratory birds.
