East Lismore Wastewater Treatment Plant, New South Wales - Operational Facility Serving 26,427 People

East Lismore wastewater treatment plant is an operational facility located on Wyrallah Road in the Lismore City Council area of New South Wales, Australia. The plant serves a population of approximately 26,427 people, placing it in the medium agglomeration category for Australian wastewater infrastructure. As an Australian plant, it operates under the national regulatory framework administered by the New South Wales Environment Protection Authority (EPA). The plant's designed capacity is 1.00 million liters per day, and it is expected to meet secondary treatment standards as per typical requirements for inland plants of this scale under the Australian Water Quality Guidelines. The plant's treated effluent is discharged into the local catchment, which ultimately drains into the Richmond River and then to the Pacific Ocean. The Richmond River supports diverse aquatic life and is an important waterway for the region's ecology and agriculture.

The plant discharges into the Richmond River catchment, which flows into the Pacific Ocean near Ballina. The river supports a variety of fish species and provides habitat for migratory birds. The surrounding floodplain is ecologically sensitive, with wetlands that help filter nutrients and sediments before they reach the coast.
