Overview
ETE CABO FRIO I is a wastewater treatment plant in Cabo Frio, Rio de Janeiro, Brazil, serving approximately 90,000 people. It is located within 50 km of the coast, discharging into the Atlantic Ocean via local waterways.
ETE CABO FRIO I is a wastewater treatment plant located in Cabo Frio, a coastal city in the state of Rio de Janeiro, Brazil. The plant serves a population of approximately 90,158 people, placing it in the medium-to-large agglomeration category for Brazilian wastewater infrastructure. Its location in the Região Sudeste region places it within a densely populated and economically active area. As a Brazilian wastewater facility, ETE CABO FRIO I operates under the national regulatory framework established by the Ministry of Cities and state environmental agencies such as INEA (Instituto Estadual do Ambiente) in Rio de Janeiro. Brazilian regulations require secondary treatment for urban wastewater, and plants serving populations over 50,000 are typically expected to meet effluent standards for organic matter and suspended solids. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating a significant infrastructure investment. The plant's treated effluent ultimately reaches the Atlantic Ocean, likely through local rivers or drainage channels that flow into the coastal waters near Cabo Frio. The region is known for its lagoons and beaches, including the Araruama Lagoon system, which is ecologically sensitive and supports diverse aquatic life. Proper treatment is essential to protect these coastal ecosystems and maintain water quality for tourism and fisheries.
Environmental context
ETE CABO FRIO I discharges into the Atlantic Ocean via local water bodies in the Cabo Frio region. The area features the Araruama Lagoon, a hypersaline coastal lagoon that supports diverse aquatic life and is an important migratory corridor for birds. The downstream environment includes sandy beaches and rocky shores that are ecologically sensitive to nutrient pollution and pathogens. Effective wastewater treatment is critical to prevent eutrophication and protect marine biodiversity in this coastal zone.
