Situated in the Centro-Oeste region, the plant serves a population of approximately 34,426 people, making it a medium-sized facility for the area. The plant is part of the municipal wastewater infrastructure managed by the local authorities. As a Brazilian wastewater treatment plant, ETE Guaxinim operates under the national regulatory framework established by the Conselho Nacional do Meio Ambiente (CONAMA) and the Ministério do Meio Ambiente. For a plant serving a population of this scale, secondary treatment is typically required to meet effluent standards. It is expected to comply with Brazilian discharge standards. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Paraná River basin. The Paraná River is one of the major rivers in South America, flowing through Brazil, Paraguay, and Argentina before reaching the Río de la Plata estuary. The plant plays a key role in protecting water quality in the region and downstream ecosystems.

The plant's treated effluent enters the local drainage network, which flows into the Paraná River basin. The Paraná River is a vital waterway supporting diverse aquatic life and providing water for agriculture, industry, and human consumption. Downstream, the river joins the Paraguay River to form the Río de la Plata, an ecologically sensitive estuary. The plant's operations help reduce nutrient and pollutant loads, protecting downstream water quality and aquatic habitats.
