The treated effluent from ETE Pedregulho SP is discharged into local water bodies that drain into the Rio Grande basin, part of the larger Paraná River system. This river network supports diverse aquatic life and provides water for agricultural and urban uses downstream. Proper treatment at this plant helps protect water quality in the region's streams and rivers, which are vital for local ecosystems and communities.

The plant's discharge enters tributaries of the Rio Grande, which flows into the Paraná River basin. This watershed supports important freshwater ecosystems, including fish populations and riparian habitats. The region's tropical climate and agricultural land use make nutrient management critical to prevent eutrophication in downstream reservoirs and rivers.
