Hackett WWTP is a municipal wastewater treatment plant located in Sebastian County, Arkansas, serving a population of 812. The facility employs advanced treatment processes to ensure high-quality effluent before discharge. As a small-scale plant, it plays a vital role in managing local wastewater in this inland community. The plant operates under the U.S. Clean Water Act, which requires NPDES permits for discharges. With advanced treatment, it likely meets stringent effluent limits for nutrients and other pollutants. The design capacity of 306.62 units and current discharge volume of 158.99 units indicate operational headroom for future growth. The treated effluent is discharged into local streams that flow into the Arkansas River, a major tributary of the Mississippi River. This downstream connection highlights the plant's role in protecting water quality in the Mississippi River Basin, supporting aquatic life and downstream communities.

The plant discharges into local waterways that drain into the Arkansas River, which flows into the Mississippi River and ultimately the Gulf of Mexico. This watershed supports diverse aquatic ecosystems and is important for migratory birds and fish. Advanced treatment helps reduce nutrient loading, which is critical for preventing hypoxia in the Gulf.
