ETE Jose Bonifacio Wastewater Treatment Plant, Jose Bonifacio, Sao Paulo, Brazil

ETE Jose Bonifacio is a municipal wastewater treatment plant located in Jose Bonifacio, in the state of Sao Paulo, Brazil. The facility serves a population of around 30,917, placing it in the medium-agglomeration category under Brazilian regulatory frameworks. The plant is situated inland, far from the coast, and its operations are subject to Brazil's environmental legislation, including CONAMA resolutions and state-level permits. Plants of this scale in Brazil typically employ secondary treatment technologies such as activated sludge or anaerobic systems, in line with national standards for organic load removal. The designed capacity is reported as 1.00, though the unit is unspecified; this suggests the plant is sized to handle the local population's wastewater volume. Operational status and permit information are not disclosed, but the facility is assumed to be active given its inclusion in public records. The treated effluent is discharged into local water bodies that drain into the Parana River basin, one of South America's major river systems. The Parana River flows southward, eventually reaching the Rio de la Plata estuary and the Atlantic Ocean. The plant's discharge contributes to the nutrient and pollutant load in the watershed, affecting downstream aquatic ecosystems and water quality in the region.

The plant discharges into local streams that are part of the Parana River basin, which drains into the Rio de la Plata estuary and the Atlantic Ocean. The watershed supports diverse aquatic life and is important for regional water supply and agriculture. Downstream ecosystems may be sensitive to nutrient enrichment from treated effluent, requiring effective treatment to maintain ecological balance.
