Ayr Brandon Wastewater Treatment Plant, Ayr, Queensland

The Ayr Brandon wastewater treatment plant is located on the Bruce Highway in Brandon, near Ayr, within the Burdekin Shire of Queensland, Australia. The facility serves a population of approximately 10,714 residents and has a designed capacity of 1.00 ML/day, reflecting its role as a medium-sized municipal treatment plant in a regional agricultural area. As an Australian plant, it operates under the national regulatory framework administered by the Queensland Department of Environment and Science, which issues environmental authorities under the Environmental Protection Act 1994. For a plant of this scale, secondary treatment is typically required to meet discharge standards that protect receiving waters. The plant discharges treated wastewater into the local environment, likely into a tributary of the Burdekin River or directly into the river system. The Burdekin River flows into the Coral Sea near the town of Ayr, supporting important coastal ecosystems including seagrass beds and mangrove forests that provide habitat for marine species.

The plant's treated effluent enters the Burdekin River catchment, which drains into the Coral Sea off the Queensland coast. This coastal zone supports diverse marine life, including dugongs and sea turtles that rely on seagrass meadows. The Burdekin River is a major waterway in tropical Queensland, and its water quality is critical for downstream ecosystems and the Great Barrier Reef lagoon.
