Overview
ETE Elis Regina is a secondary treatment plant in Lauro de Freitas, Bahia, Brazil, serving about 3,874 people. It discharges treated wastewater near the Atlantic coast, within 10 km of the shoreline.
ETE Elis Regina is a municipal wastewater treatment plant located in the Vida Nova neighborhood of Lauro de Freitas, Bahia, Brazil. The plant serves a population of approximately 3,874 residents within the Salvador metropolitan region, an area characterized by urban and coastal development. The plant provides secondary treatment, a standard level for smaller agglomerations in Brazil. Under Brazilian regulations (CONAMA resolutions and state environmental licensing), secondary treatment is typically required for inland and coastal discharges to protect water quality. The plant's discharge volume is recorded at 44.53 (units unspecified, likely cubic meters per day or similar). The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The coastal environment near Lauro de Freitas includes beaches and mangroves that support diverse aquatic life. Proper treatment is essential to minimize nutrient and pathogen loading into these sensitive coastal ecosystems.
Environmental context
The plant's discharge enters the coastal watershed of the Salvador region, flowing into the Atlantic Ocean near the Bay of All Saints (Baía de Todos os Santos). This bay is a large, ecologically productive estuary that supports mangroves, seagrass beds, and fisheries. The proximity to the coast (within 10 km) means that treated effluent can influence nearshore water quality and marine habitats, requiring effective nutrient removal to prevent eutrophication.
