Overview
ETE Cabo Frio II is a wastewater treatment plant in Cabo Frio, Rio de Janeiro, Brazil, serving approximately 16,612 people. It is located within 50 km of the coast, near the Atlantic Ocean.
ETE Cabo Frio II is a wastewater treatment facility located in Cabo Frio, a coastal city in the state of Rio de Janeiro, Brazil. The plant serves a population of about 16,612 residents, placing it in the small to medium agglomeration category. As part of Brazil's wastewater infrastructure, it contributes to the sanitation of the Região dos Lagos region, a popular tourist area. In Brazil, wastewater treatment plants are regulated under national standards such as CONAMA resolutions, which set discharge limits for pollutants. For plants of this scale, secondary treatment is typically required to protect receiving water bodies, especially in coastal areas where nutrient removal may be important to prevent eutrophication. Effluent from the plant likely discharges into local watercourses that flow into the Atlantic Ocean, given its proximity to the coast. The region's coastal lagoons and beaches are ecologically sensitive, supporting diverse aquatic life and serving as important habitats for migratory birds. Proper treatment is essential to maintain water quality for tourism, fishing, and ecosystem health.
Environmental context
The plant is situated in the coastal region of Cabo Frio, within the Região dos Lagos area. Its treated effluent likely drains into local rivers or channels that ultimately reach the Atlantic Ocean. The nearby coastal waters include the Araruama Lagoon system, a hypersaline lagoon that supports unique biodiversity and is important for local fisheries. Protecting this downstream environment from nutrient pollution and pathogens is critical for maintaining ecological balance and public health.
