ETE TARUMA Wastewater Treatment Plant, Tarumã, São Paulo, Brazil

ETE TARUMA is a wastewater treatment plant located in Tarumã, a municipality in the state of São Paulo, Brazil. The plant serves a population of around 12,832 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Water Resources Policy (Law 9.433/1997). For plants serving communities of this size, secondary treatment is typically required to reduce organic matter and suspended solids before discharge. It operates within the regulatory framework that mandates compliance with effluent quality standards. The treated effluent from ETE TARUMA is discharged into local water bodies that drain into the Paranapanema River basin, a major tributary of the Paraná River. The Paraná River system ultimately flows into the Río de la Plata estuary, supporting diverse aquatic ecosystems and providing water for agriculture, industry, and communities downstream.

ETE TARUMA discharges into local streams that feed into the Paranapanema River, a key tributary of the Paraná River. The Paraná River basin is ecologically significant, supporting diverse fish species and wetlands. Downstream, the Paraná flows into the Río de la Plata estuary, a critical habitat for migratory birds and marine life. The plant's location in an agricultural region means its effluent quality is important for protecting downstream water resources used for irrigation and drinking water.
