ETE Visconde de Maracaju - Wastewater Treatment Plant in Aracaju, Sergipe, Brazil

ETE Visconde de Maracaju is a wastewater treatment facility located in the Cidade Nova neighborhood of Aracaju, the capital of Sergipe state in northeastern Brazil. The plant serves a population of 4,791 residents within the Condominio Visconde de Maracaju area, contributing to the city's sanitation infrastructure. Brazil's wastewater treatment plants are regulated under the National Environment Council (CONAMA) resolutions and the National Water Resources Policy (Law 9.433/1997). For small agglomerations like this, secondary treatment is typically required to meet effluent standards before discharge. The plant has a designed capacity of 1.00 volume unit, indicating its scale relative to the population served. The treated effluent from ETE Visconde de Maracaju ultimately discharges into the Sergipe River basin, which flows into the Atlantic Ocean near the coast of Aracaju. This coastal region supports diverse aquatic life and is important for local fisheries and tourism. Proper treatment helps protect downstream water quality and marine ecosystems.

The plant discharges into the Sergipe River watershed, which drains into the Atlantic Ocean near Aracaju. The coastal zone is ecologically sensitive, supporting mangrove forests and estuarine habitats that serve as nursery grounds for fish and crustaceans. Maintaining treatment standards is critical to prevent nutrient enrichment and protect biodiversity in this tropical coastal environment.
