This river system supports diverse aquatic life and provides water for downstream communities, making proper treatment essential for protecting water quality and ecosystem health.

The plant discharges into streams that drain into the Paranapanema River basin, a tributary of the Paraná River. This watershed supports diverse aquatic ecosystems and provides water for agricultural and urban uses downstream. The region's Atlantic Forest biome, though fragmented, contributes to water quality and biodiversity. Proper wastewater treatment helps prevent nutrient pollution and protects sensitive aquatic habitats in this ecologically important area.
