ETE Presidente Bernardes Wastewater Treatment Plant, Presidente Bernardes, São Paulo

ETE Presidente Bernardes is a municipal wastewater treatment plant located in Vila Nova, Presidente Bernardes, within the state of São Paulo, Brazil. Serving a population of around 9,266 people, the facility is part of the region's sanitation infrastructure managed by local authorities. Brazil's wastewater treatment standards are governed by federal regulations such as CONAMA resolutions, which set effluent quality requirements. For plants of this scale, secondary treatment is typically expected to protect receiving water bodies. It operates within the framework of state-level environmental licensing. The treated effluent is discharged into local watercourses that drain into the Paraná River basin, eventually reaching the Río de la Plata estuary. The region's watershed supports agricultural activities and provides water for communities downstream. Proper treatment helps maintain water quality and aquatic ecosystem health.

The plant discharges into streams that flow into the Paraná River basin, one of South America's major river systems, which ultimately drains into the Río de la Plata estuary. The downstream environment includes agricultural lands and sensitive aquatic habitats that rely on adequate wastewater treatment to prevent nutrient loading and contamination.
