This river flows into the Gulf of Mexico, supporting diverse aquatic ecosystems and providing water for agriculture and communities downstream.

The plant discharges into local waterways that are part of the Grijalva River basin, which flows into the Gulf of Mexico. This region is ecologically sensitive, supporting mangrove forests and wetlands that provide critical habitat for fish and migratory birds. Secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream water quality and aquatic life.
