ETE Bacaxá is a municipal wastewater treatment plant located in Bacaxá, a district of Saquarema in the state of Rio de Janeiro, Brazil. The plant serves a population of approximately 30,860 people, placing it in the medium agglomeration category under Brazilian wastewater management frameworks. As a plant in Brazil, ETE Bacaxá operates under the national environmental regulations overseen by the National Water Agency (ANA) and state-level environmental agencies such as INEA Rio de Janeiro. For a plant of this scale, secondary treatment is typically required to meet effluent standards before discharge. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via coastal lagoons and rivers in the Saquarema region. The area is part of the Região dos Lagos, known for its coastal ecosystems and lagoons, including Lagoa de Saquarema. Proper treatment is essential to protect these sensitive aquatic environments and support local biodiversity.
Environmental context
The plant discharges into the watershed of the Saquarema region, which includes coastal lagoons such as Lagoa de Saquarema, connected to the Atlantic Ocean. This area supports diverse aquatic life and is important for local fisheries and tourism. The proximity to the coast (within 50 km) means that treated effluent can influence coastal water quality, making effective nutrient removal critical to prevent eutrophication in the lagoons.
