ETE Rosana is a municipal wastewater treatment plant located in Rosana, within the state of São Paulo, Brazil. The facility serves a population of about 13,860 people, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. The plant provides secondary treatment, which is the standard required under Brazilian regulations (CONAMA resolutions) for urban wastewater treatment. This level of treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. The plant reports a discharge volume of 808.27 units, indicating consistent operation. Treated effluent from ETE Rosana is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. The Paraná River flows through southeastern Brazil and into the Río de la Plata estuary, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.
Environmental context
The plant discharges into the Paraná River basin, which flows through the interior of São Paulo state and joins the Paranapanema River before reaching the Paraná River. This basin supports important aquatic habitats and is a key water resource for the region. The downstream environment includes floodplains and wetlands that provide critical ecosystem services, including water purification and habitat for fish and migratory birds.
