ETE PEDRO DE TOLEDO Wastewater Treatment Plant, Pedro de Toledo, São Paulo

ETE PEDRO DE TOLEDO is a municipal wastewater treatment plant located in Pedro de Toledo, a city in the state of São Paulo, Brazil. The plant serves a population of 3,440, classifying it as a small-scale facility within the region's sanitation infrastructure. It operates under Brazil's national environmental regulations, which mandate secondary treatment for urban wastewater to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. The plant's discharge volume is reported as 553.94 (likely in cubic meters per day or similar unit), indicating consistent operation. As a small agglomeration, it aligns with typical treatment requirements for communities of this size in Brazil. The treated effluent is discharged into local water bodies that drain into the Ribeira de Iguape River basin, an ecologically significant system in southeastern Brazil. This basin supports diverse aquatic life and flows into the Atlantic Ocean near Iguape. The plant plays a key role in protecting downstream water quality and the sensitive coastal ecosystems of the region.

The plant discharges into local streams that are part of the Ribeira de Iguape River basin, one of the last large remnants of Atlantic Forest in Brazil. This watershed supports rich biodiversity, including endangered species, and flows into the Atlantic Ocean near the Cananeia-Iguape estuary, a critical nursery for marine life. Secondary treatment helps reduce organic pollution, safeguarding this ecologically sensitive area.
