ETE Ibitiruna Wastewater Treatment Plant, Piracicaba, São Paulo

ETE Ibitiruna is a wastewater treatment plant located in the Ibitiruna district of Piracicaba, within the state of São Paulo, Brazil. The plant serves a small population of 116 residents, reflecting its role in a localized community. It operates under Brazil's national environmental regulations, which set standards for effluent quality and water resource protection. The plant provides secondary treatment, a standard level for small-scale facilities in Brazil, ensuring removal of organic matter and suspended solids. With a reported discharge volume of 26.00 m³/day, the plant manages the wastewater generated by the immediate area. The plant's design aligns with typical infrastructure for small agglomerations. The treated effluent is discharged into local water bodies that drain into the Piracicaba River basin, part of the broader Paraná River system. This region supports diverse aquatic life and is important for regional water supply and agriculture. The plant's operation helps protect downstream ecosystems and maintain water quality in the Piracicaba River watershed.

The plant discharges into the Piracicaba River basin, which flows into the Tietê River and eventually reaches the Paraná River, a major South American waterway. The Piracicaba River supports diverse aquatic species and is used for irrigation and recreation. Downstream, the Tietê River passes through urban areas before reaching the Paraná River, making effluent quality critical for ecosystem health and human use.
