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

ETE Barueri is a wastewater treatment plant located in Barueri, within the Metropolitan Region of São Paulo, Brazil. The plant serves a population of around 18,846 residents, classifying it as a small to medium agglomeration under Brazilian regulatory frameworks. It is situated in the Alphaville district, an area with significant urban and commercial development. As a facility in Brazil, ETE Barueri is subject to the National Environmental Council (CONAMA) resolutions and the National Water Resources Policy, which set standards for effluent quality and water body protection. For agglomerations of this scale, secondary treatment is typically required to reduce organic load and suspended solids before discharge. The plant's operational details, including treatment process and capacity, are managed by the local sanitation authority. The plant discharges treated effluent into the local watershed, which ultimately drains into the Tietê River basin. The Tietê River flows through the São Paulo metropolitan area and empties into the Paraná River system, eventually reaching the Río de la Plata estuary. This river system supports diverse aquatic life and is crucial for water supply, navigation, and recreation in one of South America's most densely populated regions.

ETE Barueri discharges into the Tietê River basin, a major waterway in southeastern Brazil that flows through the São Paulo metropolitan region. The Tietê River is a tributary of the Paraná River, which forms part of the La Plata Basin, one of the largest river systems in South America. The watershed supports diverse aquatic ecosystems and provides water for millions of people, industry, and agriculture. Downstream, the Paraná River feeds into the Río de la Plata estuary, a critical habitat for migratory fish and bird species. Protecting water quality in this basin is essential for maintaining ecological balance and public health in a highly urbanized area.
