The plant is situated inland, away from coastal areas, and operates as part of the municipal infrastructure for the region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 2,839.05 units and a current discharge volume of 802.51 units, the facility operates well below its capacity, indicating room for future growth. Under the U.S. Clean Water Act, such facilities are required to meet National Pollutant Discharge Elimination System (NPDES) permit limits to protect water quality. The treated effluent from Yellville WWTP is discharged into a local water body that ultimately drains into the Mississippi River Basin. The plant plays a key role in safeguarding the water quality of downstream rivers and lakes, supporting aquatic life and recreational uses in the region.

Yellville WWTP discharges into a tributary of the White River, which flows into the Mississippi River and eventually the Gulf of Mexico. The White River watershed supports diverse aquatic ecosystems, including fish and migratory birds. Advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in downstream water bodies.
