ETE MUTUM is a wastewater treatment plant located in Macaé, a city in the state of Rio de Janeiro, Brazil. The plant serves a population of approximately 16,695 people, placing it in the medium agglomeration category. Macaé is a key municipality in the Região Geográfica Imediata de Macaé-Rio das Ostras, situated in the southeastern region of Brazil. As a Brazilian wastewater facility, ETE MUTUM operates under the national regulatory framework established by the Ministry of Cities and the National Water Agency (ANA). For agglomerations of this scale, secondary treatment is typically required to meet effluent standards. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating its intended scale of operation. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The region's coastal ecosystems, including mangroves and estuaries, are sensitive to nutrient loading and require effective treatment to maintain water quality and biodiversity. The plant's proximity to the coast (within 50 km) underscores the importance of proper wastewater management to protect marine environments.
Environmental context
ETE MUTUM discharges into the Macaé River basin, which flows into the Atlantic Ocean near the city of Macaé. The downstream environment includes coastal lagoons and mangrove ecosystems that support diverse aquatic life and serve as important nursery habitats for fish and crustaceans. Effective treatment is critical to prevent eutrophication and protect the ecological health of these sensitive coastal waters.
