ETE RECREIO DE IPITANGA - Secondary Wastewater Treatment in Lauro de Freitas, Bahia

ETE RECREIO DE IPITANGA is a wastewater treatment plant located in Lauro de Freitas, within the metropolitan region of Salvador, Bahia, Brazil. The plant serves a small population of 1,168 residents, reflecting its role in a local community infrastructure. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. As a facility in Brazil, it operates under national environmental regulations, including CONAMA resolutions and state-level permitting from Bahia's environmental agency (INEMA). For small agglomerations, secondary treatment is typically adequate to meet discharge standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean near the coast of Bahia. The region's coastal ecosystems, including mangroves and estuaries, are sensitive to nutrient loading, making proper treatment essential for protecting marine biodiversity and water quality.

The plant discharges into the coastal watershed of Bahia, which flows into the Atlantic Ocean. The area supports diverse aquatic life, including mangroves and estuarine habitats that serve as nursery grounds for fish and crustaceans. Nutrient and pathogen control from secondary treatment helps mitigate eutrophication risks in the nearshore marine environment.
