ETE SANTO ESTEVAO is a municipal wastewater treatment plant located in Santo Estêvão, a city in the state of Bahia, Brazil. The plant serves a small population of 1,337 residents, reflecting its role in a smaller urban community within the Região Geográfica Imediata de Feira de Santana. The plant provides secondary treatment, which is the standard biological treatment level required for municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent from ETE SANTO ESTEVAO is discharged into local water bodies that ultimately drain into the Atlantic Ocean via the Paraguaçu River basin. The region's tropical climate and proximity to the coast make proper wastewater treatment essential for protecting downstream aquatic ecosystems and preventing nutrient pollution in coastal waters.
Environmental context
The plant discharges into the Paraguaçu River basin, which flows into the Bay of All Saints and then the Atlantic Ocean. This coastal watershed supports diverse aquatic life and is important for local fisheries. The tropical climate and seasonal rainfall patterns influence the dilution capacity of receiving waters, making consistent secondary treatment critical for maintaining water quality and preventing eutrophication in downstream estuaries.
