ETE SAO SEBASTIAO is a municipal wastewater treatment plant located in São Sebastião, within Brazil's Distrito Federal. The plant serves an estimated population of 72,359 people, making it a medium-sized agglomeration in the context of Brazilian wastewater infrastructure. It is situated in the Central-West region of Brazil, an area characterized by the Cerrado biome and a tropical savanna climate. As a Brazilian wastewater facility, ETE SAO SEBASTIAO operates under the national regulatory framework established by the Ministry of Cities and the National Water Agency (ANA). Brazilian regulations, including CONAMA Resolution 430/2011 and Law 11.445/2007, set standards for effluent quality and treatment. For a plant serving this population size, secondary treatment is typically required to meet discharge standards and protect receiving water bodies. The plant's treated effluent likely discharges into local watercourses that drain into the Paraná River basin, one of South America's major river systems. The downstream environment includes the Paranoá Lake and eventually the Paraná River, which supports diverse aquatic life and provides water for agriculture and urban use. Proper treatment is essential to prevent nutrient pollution and maintain water quality in this ecologically sensitive region.
Environmental context
The plant is located in the Distrito Federal, within the Paraná River basin. Treated effluent likely flows into local streams that feed the Paranoá Lake, a man-made reservoir that supplies Brasília's water and supports recreational activities. Downstream, waters enter the Paraná River system, which drains into the Río de la Plata estuary. The Cerrado biome surrounding the area is a biodiversity hotspot, and maintaining water quality is critical for protecting aquatic habitats and downstream ecosystems.
