ETE 1 PINDAUVINHA is a wastewater treatment plant located in Ivaiporã, in the state of Paraná, Brazil. It serves a population of 3,390, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant is situated inland, away from coastal areas, and operates under Brazil's national environmental regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater in Brazil. This process typically involves biological treatment to reduce organic matter and suspended solids. Brazilian regulations for small agglomerations often mandate secondary treatment to protect water quality. The treated effluent from ETE 1 PINDAUVINHA is discharged into local water bodies within the Paraná basin, which ultimately drains into the Paraná River system. This river system is ecologically significant, supporting diverse aquatic life and providing water for agriculture and human consumption. The plant's operation helps maintain the health of downstream ecosystems by reducing pollutant loads.

The plant discharges into the Paraná River basin, a major South American watershed that flows into the Río de la Plata estuary. The basin supports diverse aquatic habitats and is important for regional biodiversity. The secondary treatment provided by the plant helps mitigate nutrient and organic pollution, protecting downstream water quality and aquatic life.
