Overview
ETE Guarajuba is an advanced wastewater treatment plant serving Paracambi, Rio de Janeiro, Brazil. It treats wastewater for approximately 3,063 residents and discharges 402.24 cubic meters of treated effluent daily.
ETE Guarajuba is an advanced wastewater treatment plant located in Paracambi, within the state of Rio de Janeiro, Brazil. The facility serves a population of approximately 3,063 residents, making it a small-scale municipal treatment system. It operates in the Região Metropolitana do Rio de Janeiro, a densely populated region with significant water resource management challenges. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for facilities discharging into sensitive water bodies or areas with stringent environmental regulations. The plant's advanced treatment status suggests compliance with Brazilian environmental standards, such as CONAMA resolutions, which require appropriate treatment for effluent discharge. The treated effluent from ETE Guarajuba is discharged into local water bodies that eventually drain into the Atlantic Ocean via the Guanabara Bay watershed. The region's aquatic ecosystems are ecologically sensitive, supporting diverse marine and estuarine life. The plant's advanced treatment helps protect downstream water quality and contributes to the health of the broader coastal environment.
Environmental context
The plant discharges into local streams that flow into the Guanabara Bay watershed, a large estuarine system connected to the Atlantic Ocean. Guanabara Bay is ecologically important, supporting mangroves, fish nurseries, and migratory birds. The advanced treatment at ETE Guarajuba reduces nutrient loading and organic pollution, helping to mitigate eutrophication and preserve biodiversity in this coastal ecosystem.
