Koorda Wastewater Treatment Plant | Small Rural Facility in Western Australia

Koorda wastewater treatment plant is located in the small rural town of Koorda, Western Australia, within the Shire of Koorda. The plant serves a population of approximately 83 residents, reflecting its role as a small-scale municipal facility in a sparsely populated agricultural region. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. As a small agglomeration, it operates under Australian state and national wastewater regulations, which require appropriate treatment to protect public health and the environment. The plant discharges 21.60 megalitres of treated wastewater annually. The treated effluent is released into the local environment, likely into a nearby watercourse or groundwater system within the Avon River basin, which eventually drains to the Swan River and the Indian Ocean. The surrounding area is semi-arid, so the plant's discharge supports local water resources and ecosystems, though careful management is needed to prevent nutrient enrichment.

The plant discharges into the Avon River catchment, which flows westward to the Swan River and into the Indian Ocean at Perth. This semi-arid region relies on limited surface water, making the plant's treated effluent a valuable resource for local streams and groundwater recharge. The discharge supports aquatic habitats and agricultural water supplies, but requires monitoring to avoid nutrient loading in the sensitive downstream estuary.
