ETE Indiana Bela Vista do Paraíso - Secondary Wastewater Treatment Plant in Bela Vista do Paraíso, Paraná

ETE Indiana Bela Vista do Paraíso is a municipal wastewater treatment plant located in the Santa Margarida area of Bela Vista do Paraíso, in the state of Paraná, Brazil. The plant serves a population of approximately 6,294 residents, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard level required under Brazilian regulations (CONAMA resolutions) for inland wastewater discharges. This process typically involves biological treatment to remove organic matter and suspended solids. The plant treats an average of 727.49 m³ of wastewater per day, ensuring that effluent meets national quality standards before release. The treated effluent is discharged into local water bodies that are part of the Paraná River basin, one of the most significant hydrological systems in South America. The Paraná River flows southward, eventually joining the Río de la Plata estuary. The plant's operations help protect downstream aquatic ecosystems and support water quality for communities and agriculture in the region.

The plant discharges into streams within the Paraná River basin, which drains into the Paraná River and ultimately the Río de la Plata estuary. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. The secondary treatment reduces organic pollution, helping to maintain ecological balance in the receiving waters.
