Overview
ETE SAO FRANCISCO _ SANTA CLARA is a secondary treatment plant in Salvador, Bahia, Brazil, serving 735 people. It discharges 79.39 m³/day of treated wastewater near the coast.
ETE SAO FRANCISCO _ SANTA CLARA is a wastewater treatment plant located in the Jardim das Margaridas neighborhood of Salvador, Bahia, Brazil. It serves a small population of 735 residents within the metropolitan region of Salvador, the capital of Bahia state. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. Under Brazil's national environmental regulations (CONAMA resolutions), secondary treatment is appropriate for small communities, though larger agglomerations may require tertiary treatment to protect sensitive coastal waters. The plant is situated within 10 km of the Atlantic coast, discharging treated effluent into local drainage that ultimately reaches the Bay of All Saints (Baía de Todos os Santos), one of Brazil's largest and most ecologically important bays. The bay supports diverse marine life, including mangroves, coral reefs, and fisheries, making proper wastewater treatment critical for water quality and ecosystem health.
Environmental context
The plant's treated effluent flows into the Bay of All Saints (Baía de Todos os Santos), a large tropical estuary on Brazil's northeastern coast. This bay is a vital nursery for fish and crustaceans and supports extensive mangrove forests that provide coastal protection and carbon storage. The proximity to the Atlantic Ocean means that nutrient and pathogen loads from wastewater must be carefully managed to prevent eutrophication and protect recreational waters.
