ETE Deodoro is a wastewater treatment plant located in the Deodoro neighborhood of Rio de Janeiro, Brazil. Serving an estimated population of 60,209, it is part of the city's sanitation infrastructure managed by the municipal water utility. The plant is situated in the Região Metropolitana do Rio de Janeiro, a densely populated urban area. As a medium-sized agglomeration, ETE Deodoro is subject to Brazil's national environmental standards, which require secondary treatment for wastewater discharges to protect water quality. Brazilian regulations, such as CONAMA Resolution 430/2011, set effluent quality standards for organic matter and nutrients. The treated effluent from ETE Deodoro is discharged into local water bodies that drain into Guanabara Bay, a large coastal bay in southeastern Brazil. Guanabara Bay supports diverse aquatic life and is an important ecological and economic resource for the region. The plant plays a key role in reducing pollution loads to the bay, which faces challenges from urbanization and industrial activities.
Environmental context
The treated wastewater from ETE Deodoro ultimately reaches Guanabara Bay, a large estuarine system connected to the Atlantic Ocean. The bay supports mangrove forests, fish nurseries, and migratory bird populations. Protecting this ecosystem requires effective nutrient and pathogen removal to prevent eutrophication and maintain water quality for recreation and fisheries.
