ETE SAO JOAO GUARULHOS is a wastewater treatment plant located in Guarulhos, São Paulo, Brazil, serving a population of around 86,579. The plant is situated in the Metropolitan Region of São Paulo, one of the largest urban agglomerations in South America, and plays a key role in managing municipal wastewater for this densely populated area. As a plant serving a medium-sized agglomeration, it falls under Brazil's national wastewater regulations, which are enforced by state environmental agencies such as CETESB in São Paulo. Brazilian law requires adequate treatment for urban wastewater, and plants of this scale typically employ secondary treatment processes to meet discharge standards. The plant's operational details are consistent with regional practices for similar facilities. The treated effluent is discharged into local water bodies that drain into the Upper Tietê River basin, a critical watershed for the São Paulo region. The Tietê River flows through the metropolitan area and eventually reaches the Paraná River basin, which is ecologically significant for its biodiversity and water supply. Proper treatment at this plant helps protect downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into the Upper Tietê River basin, which flows through the São Paulo metropolitan region. The Tietê River is a major tributary of the Paraná River, one of South America's largest river systems, supporting diverse aquatic life and providing water for millions. Effective wastewater treatment is essential to prevent nutrient pollution and protect downstream ecosystems, including reservoirs and wetlands that are important for regional biodiversity.
