The plant plays a crucial role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal ecosystems.

The Cerralvo plant discharges into local streams that are part of the Rio Grande basin, which flows into the Gulf of Mexico. This watershed supports diverse aquatic life and is important for regional biodiversity.
