ETE Caraibas is a municipal wastewater treatment plant located in Caraíbas, a town in the state of Bahia, Brazil. The facility serves a population of approximately 2,100 people, reflecting its role in managing domestic wastewater for this small community in the northeastern region of the country. The plant operates with secondary treatment, which is the standard biological process for removing organic matter and suspended solids. Under Brazilian regulations (CONAMA resolutions and the National Water Resources Policy), secondary treatment is appropriate for communities of this size. The plant discharges an average of 170.51 cubic meters of treated effluent per day. The treated effluent from ETE Caraibas is released into local watercourses that drain into the Contas River basin, eventually reaching the Atlantic Ocean. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in the semi-arid region of Bahia, where water resources are particularly sensitive to pollution.
Environmental context
The plant discharges into the Contas River basin, which flows eastward through Bahia and empties into the Atlantic Ocean near the city of Itacaré. The region's semi-arid climate makes local water bodies vulnerable to pollution, as low flows reduce dilution capacity. Protecting these waters supports diverse aquatic life and sustains communities that rely on the river for water supply and recreation.
