ETE SEPETIBA is a wastewater treatment plant located in the Sepetiba neighborhood of Rio de Janeiro, Brazil. It serves a population of 17,203 as part of the city's municipal wastewater infrastructure. The plant is situated in the Região Metropolitana do Rio de Janeiro, a densely populated coastal region. The plant operates under Brazil's national environmental regulations, including CONAMA resolutions and state-level water quality standards. For a plant of this scale, secondary treatment is typically required to protect receiving waters. The designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a facility sized for the local population. The plant discharges into the Sepetiba Bay ecosystem, a coastal water body that supports diverse marine life and is an important fishing and tourism resource. The bay is part of the Atlantic Ocean drainage, receiving runoff from the surrounding urban and industrial areas of western Rio de Janeiro. Proper treatment is critical to prevent nutrient pollution and protect the bay's ecological health.
Environmental context
