Overview
ETE DE ARACUAI is a municipal wastewater treatment plant serving Araçuaí, Minas Gerais, Brazil. It operates under Brazil's national sanitation framework, which sets treatment standards for communities of this size.
ETE DE ARACUAI is a wastewater treatment plant located in Araçuaí, a city in the state of Minas Gerais, Brazil. The plant serves a population of approximately 12,095 residents, placing it in the small-to-medium agglomeration category under Brazilian sanitation regulations. It is situated inland, away from coastal areas, and its operations are part of the broader water management infrastructure for the Jequitinhonha River basin. Brazil's wastewater treatment standards are governed by the National Environmental Council (CONAMA) and the Ministry of Cities, with oversight from state environmental agencies. For plants serving populations around 12,000, secondary treatment is typically required to reduce organic load and suspended solids before discharge. It is expected to comply with CONAMA Resolution 430/2011, which sets effluent quality standards for wastewater discharges. The plant discharges into a local watercourse that flows into the Jequitinhonha River, one of the major rivers in eastern Brazil. The Jequitinhonha River drains into the Atlantic Ocean near the city of Belmonte. The river supports diverse aquatic life and is important for local communities, agriculture, and ecosystems. Proper treatment at ETE DE ARACUAI helps protect downstream water quality and ecological health.
Environmental context
The plant's treated effluent enters a tributary of the Jequitinhonha River, which flows eastward through Minas Gerais and Bahia before reaching the Atlantic Ocean. The Jequitinhonha basin is ecologically significant, supporting riparian forests, fish populations, and migratory birds. Downstream areas include the Jequitinhonha River estuary, which provides nursery habitat for marine species. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain water quality in this sensitive watershed.
