ETE Nova Cidade is a wastewater treatment plant located in the Nova Cidade neighborhood of Inhoaíba, in the western zone of Rio de Janeiro, Brazil. The plant serves a population of around 9,254 residents, classifying it as a small-scale facility within the metropolitan region of Rio de Janeiro. As a Brazilian wastewater treatment plant, ETE Nova Cidade is subject to CONAMA Resolution 430/2011 and other federal regulations that set effluent discharge standards. The plant's designed capacity is reported as 1.00 (likely in a unit such as m³/s or m³/h), indicating a modest scale. The treated effluent from ETE Nova Cidade is discharged into local water bodies that ultimately drain into Guanabara Bay, a large coastal bay in southeastern Brazil. Guanabara Bay is an ecologically important estuary that supports diverse aquatic life and is a key resource for local communities. The plant's operation contributes to protecting the bay's water quality from untreated sewage.
Environmental context
The plant discharges into local waterways that flow into Guanabara Bay, a major estuary on the coast of Rio de Janeiro. Guanabara Bay is a semi-enclosed system with limited water exchange, making it sensitive to nutrient pollution and organic loads. The bay supports mangrove forests, fish populations, and migratory birds, and its health is critical for both ecological balance and local livelihoods.
