ETE Carioba is a municipal wastewater treatment plant located in Americana, within the state of São Paulo, Brazil. It serves a population of approximately 158,764 people, placing it in the medium-to-large agglomeration category. The plant is situated in the Região Metropolitana de Campinas, a densely populated and industrialized region in southeastern Brazil. As a plant of this scale in Brazil, ETE Carioba is subject to federal regulations under the National Environment Council (CONAMA) and state-level water quality standards. Treatment requirements typically include secondary or advanced treatment to protect receiving water bodies. Brazilian standards for agglomerations of this size generally mandate effective nutrient removal and pathogen control. The treated effluent from ETE Carioba is discharged into local water bodies that drain into the Piracicaba River basin, which flows into the Tietê River and eventually reaches the Paraná River system. This watershed supports diverse aquatic life and provides water for agriculture, industry, and drinking water downstream. Proper treatment is critical to prevent eutrophication and protect the ecological health of the region's rivers and reservoirs.
