ETE Jales Bacia 2 Wastewater Treatment Plant, Jales, São Paulo, Brazil

ETE Jales Bacia 2 is a wastewater treatment plant located in Jales, a city in the state of São Paulo, Brazil. The plant serves a population of around 20,653 residents, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. It is situated inland, approximately 50 km from the coast, and its operations are part of the broader sanitation network for the region. Brazilian regulations require secondary treatment for plants of this scale, typically involving biological processes such as activated sludge or stabilization ponds. The plant's designed capacity is 1.00 volume unit, indicating a moderate-scale facility. Compliance with national standards set by the Ministry of Cities and state environmental agencies ensures proper effluent quality. The treated wastewater from ETE Jales Bacia 2 is discharged into local water bodies that drain into the Paraná River basin, one of South America's major river systems. This basin supports diverse aquatic ecosystems and provides water for agriculture and urban use downstream. Proper treatment is essential to protect water quality and ecological health in the region.

The plant discharges into local streams that flow into the Paraná River basin, which ultimately reaches the Rio de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply. The inland location reduces direct marine impact, but nutrient loading and pathogen control remain critical for downstream ecosystems and human use.
