Overview
ETE IGUACU I serves São José dos Pinhais, Paraná, Brazil, treating wastewater for approximately 107,000 people. The plant operates under Brazil's national environmental regulations for water quality.
ETE IGUACU I is a municipal wastewater treatment plant located in São José dos Pinhais, within the Curitiba metropolitan region of Paraná, Brazil. The facility serves a population of around 107,000, placing it in the medium-to-large agglomeration category for the region. As a Brazilian wastewater treatment plant, ETE IGUACU I operates under the framework of CONAMA resolutions and state-level environmental legislation, which mandate appropriate treatment levels to protect water resources. For a plant of this scale, secondary treatment is typically required, with possible nutrient removal in sensitive watersheds. The plant's treated effluent is discharged into local watercourses that flow into the Iguaçu River basin, a major river system in southern Brazil. The Iguaçu River ultimately drains into the Paraná River, supporting diverse aquatic ecosystems and providing water for downstream communities.
Environmental context
The plant discharges into the Iguaçu River basin, which flows through the Atlantic Forest biome, a biodiversity hotspot. The river system supports numerous fish species and provides water for agriculture and urban areas. Downstream, the Iguaçu River joins the Paraná River, which forms part of the La Plata Basin, one of the largest river systems in South America. Protecting water quality in this watershed is critical for maintaining ecological balance and human water security.
