Overview
ETE Jardim Gramacho serves 8,384 residents in Duque de Caxias, Rio de Janeiro. The plant is part of Brazil's wastewater infrastructure, discharging into the Guanabara Bay watershed.
ETE Jardim Gramacho is a wastewater treatment plant located in the Jardim Gramacho neighborhood of Duque de Caxias, within the metropolitan region of Rio de Janeiro, Brazil. It serves a population of approximately 8,384 people, classifying it as a small-scale municipal facility. The plant operates under Brazil's national environmental regulations, which require adequate treatment for discharges into sensitive water bodies. As a small agglomeration, the plant is expected to provide at least secondary treatment under Brazilian standards, consistent with the country's framework for wastewater management. The plant's location in a densely populated urban area near Guanabara Bay underscores the importance of effective treatment to protect public health and the environment. The treated effluent from ETE Jardim Gramacho ultimately drains into Guanabara Bay, a large coastal estuary in southeastern Brazil. The bay supports diverse aquatic life and is an important ecological and economic resource for the region. The plant's proximity to the bay highlights its role in mitigating pollution and preserving water quality in this sensitive coastal ecosystem.
Environmental context
The plant discharges into the Guanabara Bay watershed, a large coastal estuary that receives runoff from the Rio de Janeiro metropolitan area. The bay supports mangrove forests, fish populations, and migratory birds, making it ecologically significant. Downstream, the bay opens to the Atlantic Ocean, connecting to the South Atlantic marine ecosystem. Effective wastewater treatment is critical to reduce nutrient loading and protect this sensitive coastal environment.
