The plant's discharge enters local streams that flow into the Ouachita River, a major tributary of the Mississippi River. The Ouachita River supports diverse aquatic life, including fish and mussel species, and provides habitat for migratory birds. The advanced treatment helps minimize nutrient loading and protects downstream water quality in this ecologically sensitive watershed.
