ETE Teixeira de Freitas - Wastewater Treatment Plant in Bahia, Brazil

ETE Teixeira de Freitas is a wastewater treatment plant located in Teixeira de Freitas, a city in the state of Bahia, Brazil. The plant serves a population of approximately 109,901 people, placing it in the medium-to-large agglomeration category for the region. It is situated inland, about 50 km from the coast, and discharges into local water bodies that ultimately drain into the Atlantic Ocean. As a plant serving over 100,000 people, ETE Teixeira de Freitas is subject to Brazil's national wastewater treatment standards, which are enforced by state environmental agencies. Brazilian regulations typically require secondary treatment for urban wastewater, with more stringent requirements for discharges into sensitive water bodies. Facilities of this scale in Brazil are expected to meet secondary treatment standards under the National Environmental Council (CONAMA) resolutions. The plant's treated effluent likely flows into local rivers or streams that are part of the broader drainage network of the Atlantic coastal basin. The region is characterized by tropical climate and Atlantic Forest remnants, making proper wastewater treatment crucial for protecting downstream aquatic ecosystems and water quality. The ultimate receiving water body is the Atlantic Ocean, located approximately 50 km to the east.

The plant discharges into local watercourses that drain toward the Atlantic Ocean, passing through the coastal plain of Bahia. The region supports diverse aquatic life and is part of the Atlantic Forest biome, which is ecologically sensitive. Proper treatment is essential to prevent nutrient loading and protect downstream water quality in rivers and coastal areas.
