ETE Barra do Turvo - Secondary Wastewater Treatment Plant in Barra do Turvo, São Paulo

ETE Barra do Turvo is a wastewater treatment plant located in Barra do Turvo, a municipality in the state of São Paulo, Brazil. The plant serves a population of approximately 2,284 residents, reflecting its role in a small community within the Ribeira de Iguape River basin. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for municipalities of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring that the effluent meets basic environmental standards before discharge. The treated wastewater is discharged into local watercourses that ultimately drain into the Ribeira de Iguape River, a major river in the region that flows into the Atlantic Ocean. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the surrounding watershed.

The plant discharges into the Ribeira de Iguape River basin, which flows through the Atlantic Forest biome and empties into the Atlantic Ocean near Iguape. This region is ecologically sensitive, supporting diverse aquatic life and serving as a critical habitat for migratory fish species. The secondary treatment helps reduce nutrient and organic pollution, mitigating impacts on downstream ecosystems.
