ETE Walter Barauna Santo Amaro - Secondary Wastewater Treatment Plant in Santo Amaro, Bahia

ETE Walter Barauna Santo Amaro is a municipal wastewater treatment plant located in Santo Amaro, Bahia, Brazil. Serving a population of approximately 24,731, the plant provides secondary treatment to wastewater from the urban area. Its location in the Região Nordeste places it within a region of growing environmental awareness and regulatory oversight. The plant operates under Brazil's national wastewater regulations, which require secondary treatment for urban agglomerations of this scale. With a discharge volume of 355.49 units, the facility plays a key role in reducing pollution loads before effluent reaches the environment. The treatment process aligns with typical standards for medium-sized communities in Brazil. The treated effluent is discharged into local water bodies that flow toward the Atlantic Ocean, given the plant's proximity to the coast. This coastal setting underscores the importance of effective treatment to protect marine ecosystems and coastal water quality. The plant contributes to the broader sanitation goals of the Subaé River basin and the Todos os Santos Bay region.

The plant discharges into the Subaé River basin, which drains into Todos os Santos Bay, one of Brazil's largest and most ecologically significant coastal bays. The bay supports diverse aquatic life, including mangroves and fish species, and is an important area for local fisheries. Effective wastewater treatment is critical to prevent nutrient enrichment and maintain water quality in this sensitive coastal environment.
