The plant serves a population of 2,259 residents, classifying it as a small-scale treatment facility within the region's sanitation infrastructure. The plant provides secondary treatment, which is the standard biological treatment level required under Brazilian regulations (CONAMA resolutions) for most urban wastewater. This process typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant's discharge volume is reported at 315.63 cubic meters, indicating its operational capacity for the local community. 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 region's aquatic ecosystems benefit from the plant's treatment, which helps maintain water quality in downstream rivers and supports biodiversity in the broader watershed.

The plant's discharge enters local streams that flow into the Paraná River basin, a vast system that drains into the Río de la Plata estuary. The surrounding region is part of the Brazilian Cerrado and Atlantic Forest transition zone, supporting diverse aquatic life. Proper wastewater treatment is critical to prevent nutrient enrichment and protect downstream water quality for both ecological health and human use.
