ETE Capivari I is a wastewater treatment facility located in the Campo Grande district of Campinas, within the São Paulo state of Brazil. The plant serves a population of around 44,244, placing it in the medium agglomeration category for Brazilian wastewater infrastructure. Campinas is a major urban center in the southeastern region, and the plant plays a key role in managing the city's domestic wastewater. Under Brazil's regulatory framework, wastewater treatment plants are governed by CONAMA resolutions and state-level environmental agencies. For medium-sized agglomerations like Campinas, secondary treatment is typically required to meet effluent standards. It is expected to comply with national discharge standards set by the National Environment Council (CONAMA). The treated effluent from ETE Capivari I is discharged into local water bodies that eventually drain into the Paraná River basin, one of South America's most significant river systems. The Paraná River flows southward through Brazil, Paraguay, and Argentina before emptying into the Río de la Plata estuary. The plant's operations help protect downstream aquatic ecosystems and water quality in this extensive watershed.

The plant discharges into the Paraná River basin, which drains into the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply. The plant's effluent management helps maintain water quality in downstream rivers and contributes to the ecological health of the basin.
