ETE Fernando Prestes - Secondary Wastewater Treatment in Fernando Prestes, São Paulo

ETE Fernando Prestes is a municipal wastewater treatment plant located in Fernando Prestes, a city in the state of São Paulo, Brazil. The plant serves a population of approximately 4,643 people, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for communities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring that the effluent meets basic quality standards before discharge. The treated wastewater is discharged into local water bodies, contributing to the protection of downstream ecosystems. The plant plays a key role in maintaining water quality in the region, which ultimately drains into the Paraná River basin, one of the most important hydrological systems in South America.

The plant discharges into local streams that are part of the Paraná River basin, a major watershed that flows through southeastern Brazil and into the Río de la Plata estuary. The region's aquatic ecosystems support diverse fish species and are important for local agriculture and water supply. Proper treatment helps prevent nutrient pollution and protects downstream habitats.
