ETE Barueri Wastewater Treatment Plant - Barueri, São Paulo, Brazil

ETE Barueri is a municipal wastewater treatment plant located in Barueri, a city within the Metropolitan Region of São Paulo, Brazil. The plant serves a population of approximately 115,241 people, placing it in the medium-to-large agglomeration category. It is situated in the Alphaville district, an area known for its commercial and residential development. In Brazil, wastewater treatment plants are regulated under federal environmental laws, including CONAMA resolutions, and are overseen by state environmental agencies such as CETESB in São Paulo. For a plant of this scale, secondary treatment is typically required to meet effluent standards. It is expected to comply with national discharge standards. The plant discharges into local water bodies that are part of the Tietê River basin, which flows through the São Paulo metropolitan area. The Tietê River is a major waterway that ultimately drains into the Paraná River basin. The plant plays a critical role in protecting water quality in this heavily urbanized region, reducing pollution loads that would otherwise impact downstream ecosystems and water supply.

The plant is located in the Tietê River basin, a heavily urbanized watershed that drains the São Paulo metropolitan area. The Tietê River flows westward, eventually joining the Paraná River, which is part of the larger La Plata Basin. The river supports diverse aquatic life and provides water for millions of people, but faces significant pollution pressures from industrial and urban runoff. The plant's treatment helps mitigate these impacts, protecting downstream water quality and ecological health.
