ETE Jaguariuna Wastewater Treatment Plant, Jaguariúna, São Paulo, Brazil

ETE Jaguariuna is a municipal wastewater treatment plant located in Jaguariúna, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 29,238 people within the Campinas metropolitan region, an area characterized by a mix of urban and industrial development. As part of Brazil's wastewater infrastructure, the plant plays a key role in managing domestic sewage for this growing community. The plant operates under Brazil's national environmental regulations, which are enforced by state agencies such as CETESB in São Paulo. For a facility serving around 30,000 people, secondary treatment is typically required to meet effluent standards. The plant is expected to comply with discharge limits set by the National Environment Council (CONAMA) and state-level permits. The treated effluent from ETE Jaguariuna is discharged into local water bodies that are part of the Piracicaba River basin, which ultimately flows into the Tietê River and then to the Paraná River system. This watershed supports diverse aquatic life and provides water for downstream communities, agriculture, and industry. Proper treatment is essential to protect water quality in this ecologically and economically important region.

The plant discharges into the Piracicaba River basin, a tributary of the Tietê River, which flows into the Paraná River and eventually reaches the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems and provides water for agriculture, industry, and drinking water for millions of people. The region is ecologically sensitive due to its biodiversity and the pressure from urban and industrial activities in the Campinas metropolitan area.
