Roaring River State Park Wastewater Treatment Plant, Barry County, Missouri

Roaring River State Park wastewater treatment plant is located in Barry County, Missouri, within the Ozark Mountain region. The facility serves a small population of 505 people, primarily supporting the state park's visitors and staff. The plant provides secondary treatment, which is standard for small-scale facilities in the United States. It operates under the Clean Water Act, with discharge permits typically issued by the Missouri Department of Natural Resources. The designed capacity of 189.27 cubic meters per day matches the current discharge volume, indicating full utilization. The treated effluent is discharged into the Roaring River, a tributary of the White River system, which flows into Table Rock Lake and eventually the Mississippi River. The Ozark watershed supports diverse aquatic life, including trout populations in the park's spring-fed streams.

The plant discharges into Roaring River, a spring-fed stream that flows into the White River basin. The White River feeds Table Rock Lake, a major reservoir in the Ozarks, before joining the Mississippi River. The watershed supports cold-water fisheries, including stocked trout, and is ecologically sensitive due to karst topography that can rapidly transport pollutants to groundwater.
