Overview
ETE Sao Francisco Rio Branco is a municipal wastewater treatment plant serving Rio Branco, Acre, Brazil. It treats wastewater from approximately 48,689 people in the Amazon region.
ETE Sao Francisco Rio Branco is a municipal wastewater treatment plant located in Rio Branco, the capital of Acre state in Brazil's northern Amazon region. The plant serves a population of approximately 48,689 people, placing it in the medium-agglomeration category under Brazilian wastewater management frameworks. Brazil's wastewater treatment sector is regulated by the National Environmental Council (CONAMA) and the Ministry of Cities, with standards for effluent quality and treatment levels. For agglomerations of this scale, secondary treatment is typically required to protect receiving water bodies. The plant operates within the context of Brazil's sanitation goals, which aim to increase treatment coverage and reduce untreated discharges. The plant's treated effluent is discharged into local waterways that are part of the Amazon River basin. The region's tropical climate and high rainfall influence treatment operations and the ecological sensitivity of receiving waters. The plant plays a key role in protecting downstream aquatic ecosystems and public health in the Rio Branco area.
Environmental context
The plant discharges into tributaries of the Acre River, which flows into the Purus River and ultimately the Amazon River. The Amazon basin is one of the most biodiverse ecosystems on Earth, supporting thousands of fish species and providing critical habitat for aquatic life. The region's high rainfall and warm temperatures mean that nutrient-rich discharges can stimulate algal growth, making effective treatment essential for maintaining water quality and ecological balance.
