ETE MATA ATLANTICA Wastewater Treatment Plant, Salvador, Bahia

ETE MATA ATLANTICA is a municipal wastewater treatment plant located in the São Rafael neighborhood of Salvador, Bahia, Brazil. Serving a population of around 1,133, the plant is part of the city's sanitation infrastructure in the Northeast Region of Brazil. The plant provides secondary treatment, which is the standard biological process required for most urban wastewater in Brazil under national regulations (CONAMA resolutions). Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant's treated effluent is discharged into the local drainage system, which ultimately flows into the Atlantic Ocean. As a coastal facility within 10 km of the coast, the plant plays a key role in protecting the marine environment and coastal ecosystems of the Baía de Todos os Santos region.

The plant discharges treated wastewater into the local watershed, which drains into the Baía de Todos os Santos, a large tropical bay on the Atlantic coast of Brazil. This bay supports diverse marine life, including mangroves and coral reefs, and is an important fishing and tourism resource. Proper treatment helps prevent nutrient pollution and protect downstream ecosystems.
