Overview
ETE SARAPUI is a secondary wastewater treatment plant in Belford Roxo, Rio de Janeiro, Brazil. It serves a small population and discharges treated effluent near the coast.
ETE SARAPUI is a wastewater treatment plant located in Belford Roxo, within the metropolitan region of Rio de Janeiro, Brazil. The plant serves a small population of approximately 142 people, reflecting its role in a localized community within the densely populated state of Rio de Janeiro. The plant provides secondary treatment, which is the standard level required under Brazilian regulations for municipal wastewater. Brazil's National Environment Council (CONAMA) sets discharge standards that typically mandate secondary treatment for urban effluents. The plant's discharge volume is recorded at 33.86 (units unspecified), indicating its operational scale. The treated effluent is discharged into the local watershed, which ultimately drains into Guanabara Bay, a large coastal bay in southeastern Brazil. Guanabara Bay is an ecologically significant water body that supports diverse aquatic life and is surrounded by urban and industrial areas. The plant's proximity to the coast (within 10 km) means its discharge can influence coastal water quality and the health of the bay's ecosystem.
Environmental context
The plant discharges into the Sarapuí River, a tributary of Guanabara Bay. Guanabara Bay is a large, semi-enclosed coastal system that receives freshwater from several rivers and is connected to the Atlantic Ocean. The bay supports mangrove forests, fish populations, and migratory birds, making it an ecologically sensitive area. Urban runoff and industrial inputs further stress the bay, so the plant's secondary treatment helps reduce organic pollution loads.
