Overview
ETE Atuba Sul is a municipal wastewater treatment plant serving approximately 90,681 people in Curitiba, Paraná, Brazil. It operates under Brazil's national water quality regulations.
ETE Atuba Sul is a wastewater treatment plant located in the Cajuru district of Curitiba, Paraná, Brazil. It serves a population of approximately 90,681, placing it in the medium-to-large agglomeration category for Brazilian sanitation infrastructure. Brazil's regulatory framework for wastewater treatment is established by the National Environmental Council (CONAMA) and the National Water Agency (ANA). Plants serving populations of this scale are typically required to achieve secondary treatment or better, with effluent standards set to protect receiving water bodies. The treated effluent from ETE Atuba Sul likely discharges into a tributary of the Iguaçu River, which flows through the Curitiba metropolitan region and eventually joins the Paraná River basin. This watershed supports diverse aquatic life and provides water for downstream communities and agriculture.
Environmental context
The plant discharges into the Iguaçu River basin, which drains into the Paraná River and ultimately the Río de la Plata estuary. The Iguaçu River is ecologically significant, supporting fish populations and riparian habitats. Downstream waters are used for drinking water supply and irrigation, making effective treatment critical for water quality.
