Overview
ETE SILVIO LEAL is a secondary treatment plant in Salvador, Bahia, Brazil, serving about 1,540 people. It discharges treated wastewater near the coast, contributing to local water quality management.
ETE SILVIO LEAL is a wastewater treatment plant located in Salvador, the capital of Bahia state in northeastern Brazil. Situated in the Vila Unidos Venceremos neighborhood, this facility serves a small population of approximately 1,540 residents, addressing local sanitation needs within the metropolitan region. The plant employs secondary treatment, a standard biological process that removes organic matter and suspended solids. The plant operates under Brazil's national environmental regulations, which require adequate treatment for discharges into sensitive coastal areas. The reported discharge volume of 166.49 (likely in thousand cubic meters per year) indicates a modest operational scale. Treated effluent from the plant ultimately reaches the Atlantic Ocean via local drainage systems, given its proximity to the coast. The surrounding region includes the Baía de Todos os Santos, a large tropical bay with rich mangrove ecosystems and diverse marine life. Proper treatment helps protect these coastal waters from nutrient pollution and supports the ecological health of the bay.
Environmental context
The plant discharges into the Atlantic Ocean near Salvador, within the Baía de Todos os Santos watershed. This bay is a large, ecologically productive estuary supporting mangroves, seagrasses, and diverse fish and shellfish populations. The area is also a critical migratory corridor for seabirds and sea turtles. Effective wastewater treatment is essential to prevent eutrophication and maintain water quality in this coastal environment.
