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

ETE Barueri is a wastewater treatment plant located in Barueri, within the São Paulo metropolitan region, Brazil. It serves a population of approximately 185,600, placing it among the larger treatment facilities in the state. The plant is situated in the Alphaville district, an area with significant urban and industrial activity. As a facility of this scale in Brazil, ETE Barueri is subject to federal and state environmental regulations, including CONAMA resolutions and São Paulo state standards. These regulations typically require secondary treatment for large urban agglomerations to protect water quality. The plant's treatment process and capacity details are not publicly available, but its size suggests it plays a critical role in managing the region's wastewater. The treated effluent from ETE Barueri is discharged into local water bodies that ultimately drain into the Tietê River basin, a major tributary of the Paraná River system. The Tietê River flows through the São Paulo metropolitan area and is heavily impacted by urban runoff and industrial discharges. Downstream, the river joins the Paraná River, which empties into the Río de la Plata estuary. The plant's operation is essential for reducing pollution loads in this densely populated watershed.
