ETE AUDI is a wastewater treatment plant located in São José dos Pinhais, within the Curitiba metropolitan region in Paraná, Brazil. The plant serves a population of about 25,227, classifying it as a medium-sized municipal facility in the region. The plant provides secondary treatment, which is the standard biological treatment stage required for most urban wastewater in Brazil. Under Brazilian regulations (CONAMA resolutions), secondary treatment is typically mandated for municipalities of this scale to reduce organic load and suspended solids before discharge. The treated effluent is discharged into local water bodies that ultimately drain into the Iguaçu River basin, a major river system in southern Brazil. The Iguaçu River flows westward and eventually joins the Paraná River, forming part of the larger La Plata Basin. The plant plays a key role in protecting downstream water quality in this ecologically diverse region.
