The facility serves a small population of 37 residents and operates as part of the region's municipal wastewater infrastructure. Its location in the Meramec River watershed places it within a broader network of treatment facilities managing water quality in eastern Missouri. The plant employs advanced treatment processes, which go beyond secondary treatment to remove additional nutrients and contaminants. With a designed capacity of 26.50 million gallons per day and a current discharge volume of 3.79 million gallons per day, the facility operates well below its capacity, indicating room for future growth. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent from Terry Jean Acres WWTP ultimately discharges into the Meramec River, a major tributary of the Mississippi River. The Meramec River supports diverse aquatic life and is an important recreational resource for the region. Downstream, the Mississippi River carries the flow to the Gulf of Mexico, where nutrient loading from upstream sources contributes to the seasonal hypoxic zone. Advanced treatment at this plant helps reduce nutrient pollution in this downstream chain.
