ETE SITIO ISABEL is a wastewater treatment plant located in the Cajazeiras XI neighborhood of Salvador, Bahia, Brazil. It serves a small population of approximately 1,056 residents within the metropolitan region of Salvador, one of the largest urban areas in northeastern Brazil. The plant provides secondary treatment, which is the standard biological process for removing organic matter and suspended solids. For a facility of this scale in Brazil, secondary treatment aligns with national regulatory expectations under CONAMA resolutions, which set effluent standards for municipal wastewater. The plant discharges 114.18 m³/day of treated effluent. The treated effluent from ETE SITIO ISABEL ultimately reaches the Atlantic Ocean via local drainage systems. Salvador's coastal location means that proper wastewater treatment is critical to protect the marine environment, including nearby beaches and estuarine habitats that support diverse aquatic life and local fisheries.
Environmental context
The plant discharges into the drainage network of Salvador, which flows into Todos os Santos Bay and then the Atlantic Ocean. This bay is an ecologically important estuary supporting mangroves, fish nurseries, and migratory birds. Proper treatment is essential to prevent nutrient loading and pathogen contamination in these sensitive coastal waters.
