Brookton Wastewater Treatment Plant - Western Australia, Australia

Brookton wastewater treatment plant is located in the town of Brookton, Western Australia, within the Shire of Brookton. It serves a small population of 708 residents, reflecting its role as a local municipal facility for this rural community. The plant is operational and provides secondary treatment, which is appropriate for its scale and inland setting. As a secondary treatment facility, Brookton plant meets the standard required for inland discharge in Australia, where the National Water Quality Management Strategy sets guidelines for wastewater treatment. The plant's annual discharge volume of 183.09 megalitres indicates its capacity to handle the community's wastewater load effectively. The treated effluent is discharged into the local environment, likely into a nearby watercourse or groundwater system. The plant is located inland, over 50 km from the coast, so its discharge contributes to the Avon River catchment, which flows into the Swan River and eventually the Indian Ocean. This inland location reduces direct marine impact but requires careful management to protect freshwater ecosystems.

The plant's discharge enters the Avon River catchment, part of the Swan River basin that drains to the Indian Ocean. This inland watershed supports agricultural activities and native vegetation. The treatment process helps protect downstream water quality, including the ecologically sensitive Swan River estuary, which provides habitat for diverse aquatic life and migratory birds.
