Overview
ETE NORDESTE is a secondary wastewater treatment plant in Natal, Rio Grande do Norte, Brazil, serving approximately 6,956 people. It discharges treated effluent near the Atlantic coast.
ETE NORDESTE is a municipal wastewater treatment plant located in the Nordeste district of Natal, the capital city of Rio Grande do Norte state in northeastern Brazil. The plant serves a population of about 6,956 residents, placing it in the small-to-medium agglomeration category. Its location in the Zona Oeste area of Natal places it within an urban setting near the Potengi River estuary and the Atlantic Ocean. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for most urban wastewater. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume of 864 cubic meters per day suggests it operates at a scale appropriate for its service population. Brazilian environmental legislation, such as CONAMA 430/2011, sets effluent quality standards for discharge into water bodies. Treated effluent from ETE NORDESTE ultimately reaches the Atlantic Ocean via local drainage networks, likely through the Potengi River or its tributaries. The coastal environment of Rio Grande do Norte includes sensitive mangrove ecosystems and marine habitats that support diverse aquatic life. Proper wastewater treatment is essential to protect these coastal waters from nutrient pollution and pathogens, especially given the plant's proximity to the coast (within 10 km).
Environmental context
The plant discharges into the Potengi River basin, which flows into the Atlantic Ocean near Natal. The coastal zone includes estuarine mangroves and sandy beaches that are ecologically sensitive, supporting fish, crustaceans, and migratory birds. Nutrient and pathogen control from secondary treatment helps maintain water quality in this important coastal ecosystem.
