The plant serves a population of 1,917, classifying it as a small-scale facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment level required for municipal wastewater in Brazil under national regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring the effluent meets basic quality standards before discharge. 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 plant plays a key role in protecting local water quality and downstream ecosystems, including the Paraná River and its floodplains, which support diverse aquatic life and are important for regional biodiversity.

The plant discharges into local streams that flow into the Paraná River basin, which drains into the Río de la Plata estuary. The region's watershed supports diverse aquatic habitats and is important for migratory fish species. The plant's secondary treatment helps reduce organic pollution loads, protecting downstream water quality in this ecologically sensitive basin.
