Moro WWTP - Advanced Wastewater Treatment in Moro, Arkansas

Moro WWTP is a municipal wastewater treatment facility located on State Highway 78 in Moro, Lee County, Arkansas. It serves a small population of 216 residents, reflecting the rural character of the area. The plant is situated inland, far from coastal influences, and operates within the regulatory framework of the United States Clean Water Act. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EPA for municipal facilities. With a designed capacity of 189.27 units and an actual discharge volume of 90.85 units, the plant operates well below its capacity, indicating room for future growth. As a small facility, it is likely subject to state-level NPDES permitting under the Arkansas Department of Energy and Environment. The treated effluent is discharged into a local waterway that eventually drains into the Mississippi River basin. The plant plays a key role in protecting downstream water quality in the region, which supports diverse aquatic life and agricultural activities. Its advanced treatment ensures minimal environmental impact on the receiving waters.

The plant discharges into a local stream that flows into the Mississippi River basin, ultimately reaching the Gulf of Mexico. The region's watershed supports a mix of agricultural and natural habitats, and the advanced treatment helps reduce nutrient loading that could contribute to hypoxia in the Gulf. The plant's inland location minimizes direct marine impact.
