Darnley Erub Island Wastewater Treatment Plant, Torres Strait, Queensland

Darnley Erub Island wastewater treatment plant is located on Erub Island in the Torres Strait Island Regional area of Queensland, Australia. The plant serves a small population of 373 residents, providing essential sanitation for this remote island community. The plant operates with secondary treatment, which is appropriate for its small scale. As an Australian facility, it is subject to national water quality guidelines and state regulations under the Queensland Environmental Protection Act. The plant discharges 96.52 megaliters of treated wastewater annually. The treated effluent is discharged into the Torres Strait, a vital marine ecosystem that connects the Coral Sea to the Arafura Sea. This area supports diverse marine life, including coral reefs, seagrass beds, and important fisheries. The plant's coastal location requires careful management to protect the sensitive marine environment.

The plant discharges into the Torres Strait, a shallow sea between Australia and Papua New Guinea that connects the Coral Sea to the Arafura Sea. This marine environment supports diverse ecosystems including coral reefs, seagrass meadows, and mangrove forests, which provide habitat for dugongs, sea turtles, and numerous fish species. The Torres Strait is also an important cultural and economic resource for Indigenous communities.
