Watson WWTP discharges into tributaries of the Mississippi River, which flows into the Gulf of Mexico. The receiving waters support diverse aquatic life and are part of the larger Mississippi River ecosystem, which is ecologically significant for migratory birds and fish species. Proper treatment helps reduce nutrient loading that contributes to the Gulf of Mexico hypoxic zone.
