Wilmot WWTP discharges into local streams that flow into the Mississippi River, which drains into the Gulf of Mexico. The Lower Mississippi River watershed supports diverse aquatic ecosystems, including important fisheries and migratory bird habitats. Nutrient loading from wastewater can contribute to hypoxic zones in the Gulf, making effective treatment critical for downstream environmental health.
