ETE Nacoes Indaial is a wastewater treatment plant located in the Nações neighborhood of Indaial, Santa Catarina, Brazil. The plant serves a population of approximately 11,662 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. It is situated inland, away from the coast, and its operations are governed by Brazilian federal and state environmental standards. Brazil's wastewater treatment regulations, established by CONAMA resolutions and state-level environmental agencies, require appropriate treatment for municipal wastewater. For a plant of this scale, secondary treatment is typically expected to protect receiving water bodies. The plant's design and operational details align with the national framework for water pollution control, which emphasizes the reduction of organic load and pathogens before discharge. The plant discharges treated effluent into local watercourses that ultimately drain into the Itajaí-Açu River basin, a major watershed in Santa Catarina. This river flows eastward to the Atlantic Ocean near the port city of Itajaí. The basin supports diverse aquatic life and is important for regional water supply, agriculture, and recreation. Proper treatment at ETE Nacoes Indaial helps maintain water quality in this ecologically significant system.
Environmental context
The plant's treated effluent enters local streams within the Itajaí-Açu River basin, which drains a densely populated and industrialized region of Santa Catarina. The Itajaí-Açu River flows approximately 200 kilometers to the Atlantic Ocean, supporting estuarine and coastal ecosystems near its mouth. The watershed is home to diverse fish species and serves as a migratory corridor for aquatic fauna. Effective wastewater treatment is critical to prevent nutrient enrichment and pathogen contamination in this sensitive riverine and coastal environment.
