Woorabinda Wastewater Treatment Plant, Queensland, Australia

Woorabinda wastewater treatment plant is located on Baralaba Woorabinda Road in Woorabinda, within the Woorabinda Aboriginal Shire, Queensland, Australia. The plant serves a small population of 959 residents and is classified as a secondary treatment facility, providing biological treatment to reduce organic pollutants and suspended solids. As a secondary treatment plant, Woorabinda meets the standard requirements for municipal wastewater treatment in Australia. The plant operates under the regulatory framework of the Queensland Department of Environment and Science, which issues environmental authorities (EAs) for wastewater discharges. For a plant of this scale, typical conditions include effluent quality limits for biochemical oxygen demand (BOD) and total suspended solids (TSS), as well as monitoring and reporting obligations. The treated wastewater from Woorabinda is discharged into local waterways that ultimately drain into the Fitzroy River basin, one of Queensland's largest river systems. The Fitzroy River flows into the Coral Sea near Rockhampton, supporting diverse aquatic ecosystems including wetlands and estuarine habitats. The plant's secondary treatment helps protect these downstream environments from nutrient pollution and organic loading.

The plant discharges into local creeks that are part of the Fitzroy River basin, which flows into the Coral Sea. The Fitzroy River supports important aquatic habitats, including freshwater wetlands and estuarine zones that are critical for fish breeding and migratory birds. Secondary treatment reduces nutrient loads, helping to maintain water quality in this ecologically sensitive catchment.
