The plant serves a population of approximately 6,856 residents, classifying it as a small to medium agglomeration under Brazilian wastewater management frameworks. It operates in the southern region of Brazil, an area characterized by subtropical climate and agricultural activity. The plant provides secondary treatment, which is the standard biological treatment stage required for most municipal wastewater in Brazil under the National Environment Council (CONAMA) resolutions. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant's discharge volume is reported at 654.91 cubic meters per day, indicating consistent operational throughput. The treated effluent is discharged into local water bodies that ultimately drain into the Paraná River basin, one of South America's major river systems. The Paraná River flows southward through Brazil, Paraguay, and Argentina before emptying into the Río de la Plata estuary. The plant's operations help protect downstream aquatic ecosystems and water quality in this important regional watershed.

The plant discharges into the Paraná River basin, which drains into the Río de la Plata estuary. This watershed supports diverse aquatic life and is critical for regional water supply and agriculture. The secondary treatment provided by the plant reduces organic pollutants, helping to maintain water quality in downstream rivers and reservoirs that are ecologically sensitive.
