Overview
ETE Andorinhas is a secondary wastewater treatment plant in Santa Bárbara d'Oeste, São Paulo, Brazil, serving a small population of 222. It discharges 43.20 cubic meters of treated effluent daily.
ETE Andorinhas is a municipal wastewater treatment plant located in Santa Bárbara d'Oeste, within the Campinas metropolitan region of São Paulo state, Brazil. The plant serves a small community of 222 people, reflecting its role in local sanitation infrastructure. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for most inland water bodies. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring effluent meets basic quality standards before discharge. The treated effluent is discharged into local watercourses that drain into the Piracicaba River basin, a key water resource for the region. The Piracicaba River flows into the Tietê River, which ultimately reaches the Paraná River basin and the Río de la Plata estuary. Protecting these waters is vital for downstream communities and ecosystems.
