ETE Pedranópolis - Secondary Wastewater Treatment Plant in Pedranópolis, São Paulo, Brazil

ETE Pedranópolis is a municipal wastewater treatment facility located in Pedranópolis, a small town in the state of São Paulo, Brazil. The plant serves a population of approximately 1,463 residents, reflecting its role in a small agglomeration. It is situated near Rodovia Vicinal Aristides Pio dos Santos in the Conjunto Habitacional Alcido Borin area. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. The plant's discharge volume of 192.88 cubic meters per day indicates its operational scale. In Brazil, wastewater treatment plants are regulated under federal environmental laws and state-level permits, with secondary treatment being the minimum requirement for most municipal facilities. The treated effluent is discharged into local water bodies, contributing to the protection of the regional watershed. The plant's location within 10 km of the coast suggests that its discharge may eventually reach coastal ecosystems, though the specific receiving water body is not named. Proper treatment helps safeguard downstream aquatic life and water quality in the region.

The plant's effluent likely drains into the Paraná River basin, which flows through southeastern Brazil and ultimately reaches the Río de la Plata estuary. This watershed supports diverse aquatic habitats and is important for regional water supply. The plant's proximity to the coast (within 10 km) means that treated wastewater may influence coastal water quality, making effective nutrient removal critical to prevent eutrophication in sensitive marine environments.
