Roe WWTP - Advanced Wastewater Treatment in Monroe County, Arkansas

Roe WWTP is a municipal wastewater treatment facility located on Elm Street in Monroe County, Arkansas, serving a small population of 114 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which mandates that all publicly owned treatment works meet secondary treatment standards as a minimum. As an advanced treatment facility, Roe WWTP goes beyond secondary treatment to provide higher levels of pollutant removal, ensuring compliance with National Pollutant Discharge Elimination System (NPDES) permit requirements. The plant has a designed capacity of 56.78 m³/day and currently treats an average daily flow of 37.85 m³/day, indicating operational headroom. Advanced treatment processes typically include biological nutrient removal or filtration to reduce nitrogen, phosphorus, and suspended solids. The treated effluent is discharged into a local water body, contributing to the protection of downstream aquatic ecosystems. The facility serves a rural area in eastern Arkansas, where the landscape is dominated by agricultural land and the Mississippi River alluvial plain. The treated wastewater ultimately drains into the Mississippi River watershed, which flows into the Gulf of Mexico. This discharge supports the ecological health of local streams and rivers, which provide habitat for diverse aquatic species and are important for regional water quality.

Roe WWTP discharges into a local water body within the Mississippi River basin. The treated effluent flows through smaller streams and rivers before reaching the Mississippi River, which empties into the Gulf of Mexico. This watershed supports a variety of aquatic life, including fish and migratory birds, and is influenced by agricultural runoff. The advanced treatment helps reduce nutrient loading, which is critical for preventing hypoxia in the Gulf of Mexico.
