For plants of this scale, secondary treatment is typically expected to reduce organic load and suspended solids before discharge. The plant's treated effluent is discharged into local water bodies that eventually drain into the Atlantic Ocean via the Acarau River basin. This watershed supports diverse aquatic life and is important for regional water resources in the semi-arid Northeast region of Brazil.

The plant's discharge flows into the Acarau River basin, which drains into the Atlantic Ocean along the coast of Ceara. This watershed is ecologically significant as it supports freshwater and estuarine habitats in a semi-arid climate, where water availability is critical for both human use and biodiversity.
