ETE Paulistania - Secondary Wastewater Treatment Plant in Paulistânia, São Paulo

ETE Paulistania is a municipal wastewater treatment plant located in Paulistânia, a small town in the state of São Paulo, Brazil. The plant serves a population of about 981 people, reflecting its role in a small agglomeration. It provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. As a secondary treatment facility, ETE Paulistania meets the basic requirements for wastewater treatment in Brazil, where national regulations (CONAMA resolutions) set effluent standards for discharge. For small communities like Paulistânia, secondary treatment is typically sufficient to protect local water quality. The plant discharges approximately 216 cubic meters of treated wastewater per day. The treated effluent from ETE Paulistania is discharged into a local water body, likely a stream or river within the Paraná River basin, which ultimately drains into the Río de la Plata estuary. The plant helps protect downstream aquatic ecosystems by reducing organic pollution and nutrient loads, supporting water quality in the region's rivers and streams.

The plant discharges into a local watercourse within the Paraná River basin, which flows through southeastern Brazil and eventually reaches the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply. The secondary treatment process reduces organic pollutants and suspended solids, helping to maintain ecological balance in the receiving waters.
