Frederickton Wastewater Treatment Plant, Bellimbopinni, New South Wales

Frederickton wastewater treatment plant is located in Bellimbopinni, a locality within the Kempsey Shire Council area of New South Wales, Australia. The plant serves a population of approximately 1,865 people and operates with secondary treatment, a standard level for inland communities of this scale in Australia. As a secondary treatment facility, Frederickton uses biological processes to reduce organic matter and suspended solids before discharge. The plant handles an annual wastewater volume of 482.66 megalitres. Australian wastewater treatment plants are regulated under state and national guidelines, including the National Water Quality Management Strategy, which sets benchmarks for effluent quality to protect receiving environments. The plant's discharge enters the local catchment, which ultimately drains to the Macleay River system and then to the Tasman Sea. The Macleay River supports diverse aquatic life and is an important waterway for the region's ecosystems. The plant's secondary treatment helps minimize nutrient and pollutant loads, contributing to the health of downstream waters.

The plant discharges into the Macleay River catchment, which flows into the Tasman Sea near South West Rocks. The Macleay River supports a variety of native fish species and provides habitat for waterbirds. Downstream estuarine areas are ecologically sensitive, relying on good water quality for mangroves and seagrass beds. The plant's secondary treatment reduces organic and nutrient loads, helping protect these downstream environments.
