Middlemount Wastewater Treatment Plant, Queensland, Australia

Middlemount wastewater treatment plant is located in the town of Middlemount, Queensland, Australia, within the Isaac Regional local government area. The facility serves a population of approximately 1,943 residents, making it a small-scale municipal treatment plant. It operates under the regulatory framework of Queensland's environmental protection legislation, which aligns with national water quality standards. The plant employs secondary treatment processes, which involve biological treatment to reduce organic matter and suspended solids. This level of treatment is appropriate for the small population served and helps protect the receiving environment. The plant discharges an average of 502.81 megaliters of treated wastewater annually, contributing to local water resource management. The treated effluent from the Middlemount plant is discharged into local waterways that eventually drain into the Fitzroy River basin, one of Queensland's major river systems. The Fitzroy River flows into the Coral Sea, supporting diverse aquatic ecosystems and important coastal habitats. The plant's operations are crucial for maintaining water quality in this sensitive environment.

The Middlemount plant discharges into local creeks that are part of the Fitzroy River basin, which drains into the Coral Sea. This region supports diverse aquatic life, including species of fish and crustaceans that rely on good water quality. The plant's secondary treatment helps reduce nutrient loads, protecting downstream ecosystems from eutrophication.
