Woodenbong Wastewater Treatment Plant, New South Wales, Australia

Woodenbong wastewater treatment plant is located on Golf Links Road in Woodenbong, a small town in the Kyogle Council area of New South Wales, Australia. The plant serves a population of 919 and operates under secondary treatment, meeting Australian regulatory standards for small communities. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. The plant discharges an annual volume of 237.92 megalitres of treated wastewater. Australian wastewater treatment plants are regulated under state and national guidelines, including the National Water Quality Management Strategy, which sets performance expectations for treatment and discharge. The plant's treated effluent is released into the local catchment, which ultimately drains into the Clarence River system and then to the Tasman Sea. The surrounding area features subtropical rainforest and agricultural land, making proper treatment essential for protecting downstream water quality and aquatic ecosystems.

The plant discharges into the Clarence River catchment, which flows into the Tasman Sea near Yamba. The river supports diverse aquatic life, including migratory fish species, and is used for recreation and agriculture. The subtropical climate and forested terrain make the watershed sensitive to nutrient loading, so secondary treatment helps maintain ecological balance.
