ETE Braganca Paulista - Wastewater Treatment Plant in Bragança Paulista, São Paulo

ETE Braganca Paulista is a municipal wastewater treatment facility located in Bragança Paulista, São Paulo, Brazil. The plant serves a population of approximately 118,146 people, classifying it as a medium-to-large agglomeration under Brazilian wastewater management standards. As a plant of this scale in Brazil, it is expected to comply with national regulations such as CONAMA Resolution 430/2011, which sets effluent discharge standards. The plant discharges treated effluent into local water bodies within the Piracicaba River basin, which ultimately flows into the Tietê River and then to the Paraná River basin. This watershed supports diverse aquatic life and is important for regional water supply and agriculture.

The plant's treated effluent enters the Piracicaba River basin, a tributary of the Tietê River, which flows through São Paulo state before joining the Paraná River. This watershed is ecologically significant, supporting diverse fish species and providing water for irrigation and urban use. Downstream, the Paraná River feeds into the Río de la Plata estuary, a major ecological zone in South America.
