Palm Island Wastewater Treatment Plant, Queensland | Coastal Secondary Treatment

Palm Island wastewater treatment plant is located on Palm Island in the Palm Island Aboriginal Shire, Queensland, Australia. It serves a population of approximately 2,300 residents, providing essential wastewater management for this remote island community. The plant operates at a secondary treatment level, which is standard for small to medium agglomerations under Australian regulatory frameworks. The facility discharges an average of 599.70 megalitres of treated wastewater annually. As a coastal plant, it must comply with stringent state and national discharge standards to protect the sensitive marine environment. Treated effluent from the plant is discharged into the surrounding waters of the Coral Sea, part of the Great Barrier Reef Marine Park. This region supports diverse marine life, including coral reefs, seagrass meadows, and numerous fish species. The plant's operation is critical to maintaining water quality in this ecologically sensitive area.

The plant discharges into the Coral Sea, which is part of the Great Barrier Reef ecosystem. This area is ecologically sensitive, supporting coral reefs, seagrass beds, and marine biodiversity. The discharge must be carefully managed to avoid nutrient enrichment and other impacts on the reef's health.
