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

ETE Ipeúna is a wastewater treatment plant located in Ipeúna, a municipality in the state of São Paulo, Brazil. The plant serves a population of approximately 5,364 residents and is situated along Rodovia Irineu Penteado. It operates as part of the regional sanitation infrastructure for the Região Metropolitana de Piracicaba. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for municipalities of this size. Brazil's National Environmental Council (CONAMA) sets discharge standards that mandate adequate treatment to protect water quality. The plant's average daily discharge volume is 860.87 m³, reflecting the scale of the community it serves. The treated effluent is discharged into local water bodies that ultimately drain into the Piracicaba River basin, a key tributary of the Tietê River. The Tietê River flows through São Paulo state and eventually reaches the Paraná River basin. The plant plays a crucial role in protecting downstream aquatic ecosystems and supporting water quality in the region.

The plant discharges into the Piracicaba River basin, which flows into the Tietê River, a major watercourse in São Paulo state. The Tietê River eventually joins the Paraná River, one of South America's largest river systems. The watershed supports diverse aquatic life and is important for regional water supply and agriculture. Secondary treatment helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream reservoirs.
