Mundaring Wastewater Treatment Plant | Western Australia, Australia

Mundaring wastewater treatment plant is an operational facility located in the Shire of Mundaring, Western Australia, serving a population of around 22,127. The plant is situated inland, away from coastal areas, and plays a key role in managing wastewater for the local community. As a medium-sized agglomeration, the plant is expected to meet Australian regulatory standards for wastewater treatment, which typically require secondary treatment and nutrient removal to protect receiving environments. The plant's designed capacity is 1.00 million liters per day, indicating a scale appropriate for its service population. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Swan River and then into the Indian Ocean. The plant helps protect the ecological health of the Swan River estuary, a vital habitat for aquatic life and migratory birds.

The plant discharges into the Swan River catchment, which flows into the Indian Ocean near Perth. The Swan River estuary supports diverse aquatic life, including fish and crustaceans, and is an important ecological corridor. The plant's operations help maintain water quality in this sensitive downstream environment.
