ETE BALSAMO Wastewater Treatment Plant, Bálsamo, São Paulo, Brazil

ETE BALSAMO is a wastewater treatment plant located in Bálsamo, a municipality in the state of São Paulo, Brazil. The plant serves a population of 7,783, placing it in the small agglomeration category under Brazilian regulations. It is situated in the southeastern region of the country, an area characterized by intensive agriculture and urban development. The plant operates under Brazil's national environmental framework, which includes CONAMA resolutions and state-level licensing by CETESB in São Paulo. For small agglomerations, secondary treatment is typically required to protect receiving water bodies. The designed capacity of 1.00 suggests a modest scale, though the unit is unspecified. The plant's treated effluent is discharged into local watercourses that drain into the Paraná River basin, one of South America's largest river systems. This basin supports diverse aquatic life and provides water for millions of people. Proper treatment is essential to prevent nutrient pollution and maintain water quality in downstream ecosystems.

The plant discharges into local streams that flow into the Paraná River basin, which ultimately reaches the Río de la Plata estuary. This watershed supports important fisheries and agricultural irrigation. The region's tropical climate and intensive farming increase the risk of nutrient runoff, making effective wastewater treatment critical for preventing eutrophication in downstream water bodies.
