Aurora Wastewater Treatment Plant, Melbourne, Victoria

Aurora is a wastewater treatment plant located in Wollert, within the City of Whittlesea, Melbourne, Victoria, Australia. It serves a population of around 176,451, classifying it as a large agglomeration under Australian regulatory frameworks. The plant is operational and plays a key role in managing wastewater for this growing urban area. As a large-scale facility, Aurora is expected to meet stringent treatment standards under the Victorian Environment Protection Authority (EPA) regulations, which require advanced treatment for inland discharges to protect water quality. The plant's designed capacity is 1.00 million liters per day, indicating a substantial infrastructure investment to handle the region's wastewater. The treated effluent from Aurora is discharged into local waterways that ultimately flow into Port Phillip Bay, a significant marine environment. The plant's operations help safeguard the ecological health of these water bodies, supporting aquatic life and recreational uses downstream.

Aurora's treated wastewater discharges into the Merri Creek catchment, which flows into the Yarra River and then into Port Phillip Bay. This bay is a ecologically sensitive marine environment that supports diverse aquatic life, including fish, birds, and invertebrates. The plant's treatment processes are crucial for minimizing nutrient and pollutant loads, thereby protecting the bay's water quality and ecosystem health.
