Ozark WWTP - Municipal Wastewater Treatment Plant in Ozark, Arkansas

Ozark WWTP is a municipal wastewater treatment facility located on Hillbilly Loop in Ozark, Franklin County, Arkansas. The plant serves a population of about 3,684 people, classifying it as a small agglomeration under U.S. regulatory frameworks. As part of the state's wastewater infrastructure, it plays a key role in managing domestic sewage from the community. Under the U.S. Clean Water Act, municipal wastewater treatment plants of this scale are typically required to meet secondary treatment standards as defined by the EPA. The facility operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Arkansas Department of Energy and Environment - Division of Environmental Quality. These permits set effluent limits to protect water quality in receiving streams. The plant's treated effluent ultimately drains into the Arkansas River watershed, which flows southeast to the Mississippi River and then to the Gulf of Mexico. The receiving water body supports diverse aquatic life and is used for recreation and water supply downstream. Proper treatment at this facility helps maintain water quality in the region's surface waters.

The plant discharges into local tributaries of the Arkansas River, a major waterway that flows through Arkansas and joins the Mississippi River. The Arkansas River basin supports diverse fish populations and provides habitat for migratory birds. Downstream waters are used for recreation, agriculture, and municipal supply, making effective wastewater treatment essential for maintaining ecological health and meeting water quality standards.
