Iama Island Wastewater Treatment Plant, Torres Strait, Queensland

The Iama Island wastewater treatment plant is located on Iama Island in the Torres Strait Island Regional area of Queensland, Australia. It serves a small population of 315 residents, providing essential sanitation infrastructure for this remote island community. The plant is situated near the airstrip, reflecting the island's isolated character. The plant operates with secondary treatment, which is appropriate for its small scale. As an Australian facility, it is subject to the national regulatory framework for wastewater management, including state-level environmental protection requirements in Queensland. The plant's discharge volume is approximately 81.51 megaliters per year, indicating a modest flow consistent with the small population served. The treated wastewater is discharged into the marine waters surrounding Iama Island, which are part of the Torres Strait. This region is ecologically significant, supporting diverse marine life including coral reefs, seagrass meadows, and important fisheries. The plant's coastal location and secondary treatment level mean that careful management is needed to protect the sensitive marine environment.

Iama Island lies in the Torres Strait, a shallow sea between Australia and Papua New Guinea. The surrounding waters are part of the Great Barrier Reef Marine Park and support diverse marine ecosystems, including coral reefs, seagrass beds, and habitats for dugongs and sea turtles. The plant's discharge enters this sensitive marine environment, where nutrient and pathogen control are critical for maintaining water quality and ecosystem health.
