Gibson Island A Wastewater Treatment Plant, Murarrie, Queensland

Gibson Island A is a large wastewater treatment plant located in Murarrie, a suburb of Brisbane, Queensland, Australia. Serving a population of approximately 207,765, it is a key facility in the region's wastewater infrastructure, handling a significant portion of the Greater Brisbane area's sewage. The plant operates under Australia's national water quality management framework, which includes the National Water Quality Management Strategy and state-level regulations from the Queensland Department of Environment and Science. The plant's treated effluent ultimately drains into the Brisbane River, which flows into Moreton Bay, a large coastal embayment of the Coral Sea. This bay supports diverse marine life, including seagrass meadows and fish nurseries, making the plant's discharge quality critical for local ecosystem health.

Gibson Island A discharges into the Brisbane River, which flows into Moreton Bay, a semi-enclosed coastal bay of the Coral Sea. Moreton Bay is ecologically significant, supporting seagrass beds, mangroves, and a variety of marine species. The plant's location within 50 km of the coast means its effluent can influence coastal water quality, particularly during high-flow events.
