Overview
ETE Atuba Sul is a wastewater treatment plant in Curitiba, Paraná, Brazil, serving approximately 13,690 people. It operates under Brazil's national water quality regulations.
ETE Atuba Sul is a wastewater treatment plant located in the Cajuru district of Curitiba, in the state of Paraná, Brazil. The plant serves a population of around 13,690 residents, placing it in the small-to-medium agglomeration category for Brazilian wastewater infrastructure. As a municipal facility in Brazil, ETE Atuba Sul is subject to the country's environmental standards, including CONAMA Resolution 430/2011, which sets effluent discharge limits. The treated effluent from ETE Atuba Sul is discharged into local waterways that ultimately drain into the Iguaçu River basin, a major river system in southern Brazil. The Iguaçu River flows westward to the Iguaçu Falls and then into the Paraná River, which forms part of the larger Río de la Plata Basin. This downstream environment supports diverse aquatic life and is important for regional water resources.
Environmental context
The plant's treated effluent enters the local drainage network within the Iguaçu River basin, which flows through the Atlantic Forest biome. The Iguaçu River is ecologically significant, supporting species such as the neotropical otter and various migratory fish. Downstream, the river contributes to the Paraná River system, which ultimately reaches the Río de la Plata estuary. Protecting water quality in this watershed is critical for maintaining biodiversity and water supply for downstream communities.
