Coutts Crossing Wastewater Treatment Plant | Secondary Treatment, Clarence Valley, NSW

Coutts Crossing wastewater treatment plant is located in the small rural community of Coutts Crossing, New South Wales, Australia. The facility serves a population of approximately 1,934 residents and operates under secondary treatment processes, which is appropriate for a community of this size in a non-sensitive inland area. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant is regulated under New South Wales environmental protection laws, which require compliance with discharge limits to protect receiving water quality. The facility's operational status is active, and it manages an average daily flow of around 500 cubic meters. The treated effluent is discharged into the local catchment, which ultimately drains into the Clarence River system. The Clarence River is one of Australia's largest coastal rivers, supporting diverse aquatic ecosystems and important fisheries. The plant's inland location reduces direct marine impact, but its discharge contributes to the overall water quality of the river basin.

The plant discharges into the Clarence River catchment, which flows into the Tasman Sea near Yamba. The Clarence River supports a range of aquatic life, including migratory fish species and estuarine habitats. The region's subtropical climate and agricultural land use mean that nutrient management from wastewater is important to prevent algal blooms and maintain water quality downstream.
