Overview
ETE Sarapui is a municipal wastewater treatment plant in Belford Roxo, Rio de Janeiro, Brazil, serving approximately 62,879 people. It operates within the regulatory framework of Brazil's national water and sanitation policies.
ETE Sarapui is a municipal wastewater treatment plant located in Belford Roxo, within the metropolitan region of Rio de Janeiro, Brazil. The plant serves a population of approximately 62,879 residents, placing it in the medium-agglomeration category under Brazilian sanitation standards. Its location in the Região Sudeste places it within a densely populated urban area with significant industrial and residential wastewater management needs. As a plant in Brazil, ETE Sarapui operates under the national regulatory framework established by the National Water Agency (ANA) and state environmental agencies. For agglomerations of this scale, Brazilian regulations typically require secondary treatment or equivalent to protect water quality. The plant's treated effluent is discharged into local water bodies that ultimately drain into Guanabara Bay, a large coastal bay in Rio de Janeiro state. Guanabara Bay is an ecologically significant estuary that supports diverse aquatic life and is a critical resource for local communities. The bay's health is influenced by wastewater inputs from the surrounding metropolitan area, making treatment plants like ETE Sarapui important for reducing pollution loads and protecting downstream ecosystems.
Environmental context
ETE Sarapui discharges into the Sarapui River, a tributary of Guanabara Bay. The bay is a large, semi-enclosed estuary that receives drainage from several rivers in the Rio de Janeiro metropolitan area. It supports mangrove forests, fish populations, and migratory bird species. The ecological health of Guanabara Bay is sensitive to nutrient and pollutant loads from urban runoff and treated wastewater, making effective treatment essential for maintaining water quality and biodiversity.
