ETE Alegria Resende is a wastewater treatment plant located in Resende, a city in the state of Rio de Janeiro, Brazil. The plant serves a population of around 20,500 residents, placing it in the small-to-medium agglomeration category. It is situated in the Baixada da Olaria neighborhood, within the Paraíba do Sul river basin, an important water resource for the region. As a Brazilian wastewater facility, ETE Alegria Resende is subject to the National Environmental Council (CONAMA) resolutions and state-level environmental licensing from INEA (Instituto Estadual do Ambiente). For agglomerations of this size, secondary treatment is typically required to meet effluent standards for organic matter and suspended solids. It is expected to comply with applicable discharge limits. The treated effluent from the plant likely discharges into a local watercourse that flows into the Paraíba do Sul River, which ultimately reaches the Atlantic Ocean near Campos dos Goytacazes. The Paraíba do Sul basin supports diverse aquatic life and provides water for multiple municipalities, making proper treatment essential for downstream water quality and ecosystem health.
Environmental context
The plant is located in the Paraíba do Sul River basin, which drains a densely populated and industrialized region of southeastern Brazil. The river flows approximately 1,100 km to the Atlantic Ocean, supporting agriculture, hydropower, and drinking water supplies. Downstream ecosystems include floodplain forests and coastal lagoons that are ecologically sensitive. Effective wastewater treatment at ETE Alegria Resende helps reduce nutrient and pathogen loads, protecting aquatic biodiversity and water quality for downstream communities.
