Overview
ETE VILA DO BOSQUE is a secondary wastewater treatment plant in Salvador, Bahia, Brazil, serving a population of 405. It discharges 43.81 units of treated effluent and is located within 10 km of the coast.
ETE VILA DO BOSQUE is a wastewater treatment plant located in Salvador, the capital of Bahia state in northeastern Brazil. The plant serves a small population of 405 people and operates at a secondary treatment level, which is typical for smaller communities in the region. However, Brazilian wastewater treatment plants are regulated by the National Environment Council (CONAMA) and state environmental agencies, which set discharge standards based on the receiving water body and treatment level. For secondary treatment, typical standards include removal of organic matter and suspended solids. The plant discharges treated effluent into the local watershed, which ultimately drains into the Atlantic Ocean. Salvador's coastal location means that the plant's discharge affects the marine environment, including the Bay of All Saints (Baía de Todos os Santos), an important estuarine ecosystem that supports diverse aquatic life and local fisheries.
Environmental context
The plant is situated in Salvador, a coastal city on the Bay of All Saints (Baía de Todos os Santos), which is a large estuarine system connected to the Atlantic Ocean. The bay supports mangrove forests, seagrass beds, and coral reefs, providing critical habitat for fish, crustaceans, and migratory birds. Treated effluent from the plant enters this sensitive marine environment, where nutrient loading and contaminants can impact water quality and ecosystem health.
Frequently asked questions
ETE VILA DO BOSQUE is located in Salvador, the capital city of Bahia state in northeastern Brazil. The plant serves the Vila do Bosque area within the metropolitan region of Salvador.
The plant provides secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. This level of treatment is common for small to medium-sized communities in Brazil.
The treated effluent is discharged into the local watershed, which flows into the Bay of All Saints (Baía de Todos os Santos) and eventually the Atlantic Ocean. The plant's proximity to the coast (within 10 km) means its discharge directly affects the marine environment.
Brazilian wastewater treatment plants are regulated by the National Environment Council (CONAMA) and state environmental agencies. CONAMA Resolution 430/2011 sets effluent discharge standards for pollutants such as BOD, COD, and nutrients, which apply to plants like ETE VILA DO BOSQUE.
For small populations of about 400 people, Brazilian regulations often require at least secondary treatment. Many such plants use compact systems like septic tanks followed by anaerobic filters or constructed wetlands, though specific processes vary by location and operator.
