Overview
ETE Centro Nova Friburgo is a municipal wastewater treatment plant serving approximately 58,649 people in Nova Friburgo, Rio de Janeiro, Brazil. It operates under Brazil's national water quality regulations.
ETE Centro Nova Friburgo is a wastewater treatment plant located in Nova Friburgo, a city in the mountainous region of Rio de Janeiro state, Brazil. The plant serves a population of around 58,649 residents, classifying it as a medium-sized agglomeration under Brazilian sanitation standards. It is situated along RJ-116, a major regional road, and plays a key role in managing the city's domestic sewage. Brazil's wastewater treatment framework is governed by the National Water Resources Policy (Law 9.433/1997) and CONAMA resolutions, which set discharge standards for pollutants like BOD and nutrients. For a plant of this scale, secondary treatment is typically required to meet these standards. The regulatory context ensures that facilities serving populations over 50,000 are subject to stringent monitoring and permitting by state environmental agencies such as INEA (Instituto Estadual do Ambiente) in Rio de Janeiro. The treated effluent from ETE Centro Nova Friburgo is discharged into local watercourses that drain into the Macaé River basin, which flows southeast to the Atlantic Ocean. The region's mountainous terrain and Atlantic Forest biome make the watershed ecologically sensitive, supporting diverse aquatic life and providing water for downstream communities. Proper treatment is essential to protect these ecosystems and maintain water quality for recreational and drinking water uses.
Environmental context
The plant's treated effluent enters local streams that feed into the Macaé River basin, which ultimately discharges into the Atlantic Ocean near the city of Macaé. This watershed is part of the Atlantic Forest biome, a globally significant biodiversity hotspot. The region's steep slopes and high rainfall increase the risk of runoff and erosion, making effective wastewater treatment crucial to prevent nutrient loading and sedimentation in downstream rivers and coastal waters. The receiving waters support fish populations and provide water for agriculture and urban supply in the lower basin.
