ETE PARANOA Wastewater Treatment Plant, Paranoá, Distrito Federal, Brazil

ETE PARANOA is a wastewater treatment plant located in Paranoá, within the Distrito Federal of Brazil. It serves a population of approximately 45,988 people, making it a medium-sized facility in the Brasília metropolitan area. The plant is situated in the Central-West region of Brazil, an area characterized by its tropical savanna climate and the Cerrado biome. As a plant in Brazil, ETE PARANOA operates under the national regulatory framework established by the National Environment Council (CONAMA) and the National Water Agency (ANA). For a facility serving around 46,000 people, secondary treatment is typically required to meet effluent standards. It is expected to comply with CONAMA Resolution 430/2011, which sets discharge standards for wastewater treatment plants. The plant's treated effluent is discharged into the local watershed, which is part of the Paraná River basin. The receiving water body is likely a tributary of the Paranoá River or Lake Paranoá, an artificial lake created in Brasília. The downstream environment includes the Paranoá River, which flows into the São Bartolomeu River and eventually the Paraná River, supporting diverse aquatic life and providing water for agricultural and urban uses.

ETE PARANOA discharges into the Paranoá River basin, which flows into Lake Paranoá, an artificial lake in Brasília. The lake is a key water resource for the region, supporting recreation and biodiversity. Downstream, the Paranoá River joins the São Bartolomeu River, part of the Paraná River basin, which ultimately drains into the Río de la Plata estuary. The Cerrado biome surrounding the watershed is ecologically sensitive, with high endemism and seasonal flooding patterns that influence water quality.
