The plant serves an estimated population of 91,287, placing it in the medium-to-large agglomeration category for Brazilian wastewater infrastructure. Brazil's wastewater treatment standards are governed by CONAMA Resolution 430/2011 and the National Basic Sanitation Plan (PLANSAB). For plants of this scale, secondary treatment is typically required to meet effluent quality standards before discharge into receiving waters. The plant's operational details and treatment processes are managed by the local sanitation authority. The plant's treated effluent is discharged into the Paranaíba River basin, which flows into the Paraná River and eventually reaches the Río de la Plata estuary. This waterway supports diverse aquatic life and is important for regional water supply and agriculture.

The plant discharges into the Paranaíba River basin, a major tributary of the Paraná River system. The Paraná River flows through Brazil, Paraguay, and Argentina before emptying into the Río de la Plata estuary. This watershed supports diverse aquatic ecosystems, including migratory fish species, and provides water for irrigation and human consumption in the region.
