The proximity to the Iguaçu National Park and the Iguaçu Falls adds environmental sensitivity to the area.

The plant discharges into the Paraná River basin, which flows southward to join the Río de la Plata estuary. This watershed supports important aquatic ecosystems, including migratory fish species and riparian habitats. The region's subtropical climate and proximity to the Iguaçu Falls area make it ecologically sensitive, requiring careful management of nutrient loads and pollutants to prevent eutrophication and protect biodiversity.
