Emerald Wastewater Treatment Plant, Queensland | Australia

The Emerald wastewater treatment plant is located in the Central Highlands region of Queensland, Australia, serving the town of Emerald. The plant is operational and serves a population of around 13,787, placing it in the medium agglomeration category for Australian wastewater management. As a treatment facility in Australia, the plant operates under the national regulatory framework administered by the Queensland Department of Environment and Science. Australian wastewater treatment standards typically require secondary treatment for inland plants, with additional nutrient removal in sensitive catchments. The plant's treatment processes are designed to meet local environmental protection requirements. The treated effluent from the plant is discharged into the local environment, likely contributing to the Nogoa River system, which flows into the Fitzroy River and ultimately reaches the Coral Sea. The receiving waters support aquatic ecosystems and are important for regional agriculture and biodiversity.

The plant discharges into the Nogoa River catchment, part of the Fitzroy Basin, which flows into the Coral Sea. The Fitzroy Basin is one of Queensland's largest river systems, supporting diverse aquatic life and important for regional agriculture. The plant's operations help protect downstream water quality in this ecologically significant basin.
