ETE BARAO DE ANTONINA is a municipal wastewater treatment plant located in Barão de Antonina, a small town in the state of São Paulo, Brazil. The plant serves a population of approximately 1,800 residents, reflecting the scale of a small community in the southeastern region of the country. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for smaller agglomerations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring the effluent meets basic quality standards before discharge.
