Overview
ETE SAO PAULO SALVADOR is a secondary treatment plant in Salvador, Bahia, Brazil, serving a small population of 86. It discharges treated wastewater near the coast of the Atlantic Ocean.
ETE SAO PAULO SALVADOR is a wastewater treatment plant located in the Novo Marotinho neighborhood of Salvador, Bahia, Brazil. The plant serves a small population of 86 people and operates with secondary treatment, which is the minimum standard required under Brazilian regulations for most urban wastewater. Its location in the metropolitan region of Salvador places it within a densely populated coastal area. As a secondary treatment facility, the plant removes organic matter and suspended solids through biological processes, meeting the basic effluent standards set by the Brazilian National Environment Council (CONAMA). For a plant of this small scale, secondary treatment is typical and sufficient to protect public health and the environment. The plant's discharge volume is 9.29 cubic meters per day, reflecting its small service population. The plant discharges treated wastewater into the local drainage system, which ultimately flows into the Atlantic Ocean near Salvador. The coastal waters of Bahia support diverse marine ecosystems, including coral reefs and mangroves, making proper treatment essential to prevent nutrient pollution and protect aquatic life. The plant's proximity to the coast underscores the importance of effective secondary treatment in safeguarding coastal water quality.
Environmental context
The plant's treated effluent enters the local watershed in Salvador, which drains into the Atlantic Ocean via small coastal streams and the Baía de Todos os Santos. This bay is a large tropical estuary that supports mangroves, seagrass beds, and coral reefs, providing critical habitat for fish, crustaceans, and migratory birds. Nutrient and pathogen pollution from untreated or inadequately treated wastewater can harm these ecosystems, making secondary treatment vital for maintaining water quality and biodiversity in the region.
