Overview
ETE BOCA DA MATA is a secondary wastewater treatment plant in Salvador, Bahia, Brazil, serving 818 people. It discharges 88.42 units of treated effluent and is located within 10 km of the coast.
ETE BOCA DA MATA is a wastewater treatment facility located in the Boca da Mata neighborhood of Salvador, the capital of Bahia state in northeastern Brazil. The plant serves a small population of 818 residents, reflecting its role in localized sanitation infrastructure within the broader metropolitan region of Salvador. The plant provides secondary treatment, which is the standard biological treatment process required under Brazilian regulations (CONAMA resolutions) for most municipal wastewater. This level of treatment removes organic matter and suspended solids, reducing the pollutant load before discharge. Situated near the Atlantic coast, the plant's treated effluent likely discharges into local water bodies that flow into the Bay of All Saints (Baía de Todos os Santos), one of Brazil's largest and most ecologically significant bays. The bay supports diverse marine life, including mangroves and estuaries, and is an important fishing and tourism resource for the region. Proper treatment is essential to protect these coastal ecosystems from nutrient pollution and pathogens.
Environmental context
The plant is located in Salvador, on the eastern coast of Brazil, within the watershed of the Bay of All Saints (Baía de Todos os Santos). This large tropical bay receives freshwater from several rivers and is a critical habitat for mangroves, fish, and migratory birds. The bay's waters ultimately connect to the Atlantic Ocean. Discharges from coastal plants like ETE BOCA DA MATA must be carefully managed to prevent eutrophication and maintain water quality for recreation and fisheries.
