Proper treatment helps protect downstream water quality and the sensitive coastal ecosystems of southeastern Brazil.

The plant discharges into the Doce River basin, which flows eastward through Espírito Santo and empties into the Atlantic Ocean. This watershed supports diverse aquatic ecosystems and is a critical resource for local communities. The region's tropical climate and coastal proximity make the receiving waters sensitive to nutrient pollution, emphasizing the importance of secondary treatment in maintaining ecological balance.
