The treated effluent from ETE Vitoria Dois Irmaos is discharged into nearby water bodies that ultimately drain into the Rio dos Sinos basin, part of the larger Laguna dos Patos system. This watershed supports diverse aquatic life and provides water for downstream communities. Proper treatment at this plant helps maintain the ecological health of the region's waterways.

The plant discharges into local streams that flow into the Rio dos Sinos, a major river in Rio Grande do Sul. The Rio dos Sinos basin is ecologically significant, supporting fish populations and serving as a water source for the Porto Alegre metropolitan area. Downstream, the river drains into the Laguna dos Patos, a large coastal lagoon connected to the Atlantic Ocean. Protecting this watershed through effective wastewater treatment is crucial for maintaining water quality and biodiversity in the region.
