Overview
ETE AREIA BRANCA 02 is a secondary treatment plant serving 3,609 people in Lauro de Freitas, Bahia, Brazil. It discharges 41.48 units of treated wastewater and is located within 10 km of the coast.
ETE AREIA BRANCA 02 is a wastewater treatment plant located in the Conjunto Habitacional Adélia do Prado Franco, in the municipality of Lauro de Freitas, Bahia, Brazil. The plant serves a population of 3,609 and is part of the metropolitan region of Salvador, the capital of Bahia state. As a secondary treatment facility, it provides biological treatment to remove organic matter and suspended solids from municipal wastewater. The plant operates under Brazil's national environmental regulations, which are enforced by state environmental agencies such as INEMA (Instituto do Meio Ambiente e Recursos Hídricos) in Bahia. For a plant of this scale, secondary treatment is the standard requirement to protect receiving water bodies. Located less than 10 km from the Atlantic coast, the plant's discharge likely reaches coastal waters via local drainage systems. This proximity to the ocean underscores the importance of effective treatment to prevent nutrient pollution and protect marine ecosystems. The region's tropical climate and urban density in the Salvador metropolitan area add to the environmental sensitivity of the area.
Environmental context
The plant's treated effluent ultimately drains into the Atlantic Ocean via the coastal watershed of Bahia. The region includes mangrove ecosystems and estuarine habitats that support diverse aquatic life, including fish and crustaceans important for local fisheries. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making secondary treatment a critical safeguard for water quality and marine biodiversity.
