Overview
ETE LAGOA AERADA is a wastewater treatment plant serving approximately 16,346 people in Natal, Rio Grande do Norte, Brazil. It operates under Brazil's national water quality regulations.
ETE LAGOA AERADA is a wastewater treatment plant located in the Bom Pastor neighborhood of Natal, the capital of Rio Grande do Norte state in northeastern Brazil. The plant serves a population of about 16,346 residents, placing it in the medium-sized agglomeration category for the region. Brazil's wastewater treatment facilities are regulated under the National Environmental Council (CONAMA) resolutions and the National Water Resources Policy (Law 9.433/1997). For plants serving populations around 16,000, secondary treatment is typically required to meet effluent standards before discharge. The treated effluent from ETE LAGOA AERADA ultimately drains into the Atlantic Ocean via the Potengi River estuary, which is a critical coastal ecosystem. The Potengi River flows through Natal and supports mangrove forests and estuarine habitats that are important for local fisheries and biodiversity. Proper treatment is essential to protect these sensitive coastal waters from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Potengi River, which flows through Natal and empties into the Atlantic Ocean via a large estuary. This estuarine system supports mangrove forests and serves as a nursery for fish and crustaceans, making it ecologically sensitive to nutrient loading and contamination. The downstream coastal waters are part of the northeastern Brazilian marine ecosystem, which includes coral reefs and seagrass beds.
