Viburnum Trailer PK Lag Wastewater Treatment Plant, Viburnum, Missouri

Viburnum Trailer PK Lag is a wastewater treatment plant located in Viburnum, Iron County, Missouri, United States. It serves a small population of 185 residents, primarily from the Saint Joe Trailer Court area. The plant is classified as a small-scale facility operating under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level required for municipal wastewater in the United States. Its designed capacity is 151.42 megaliters, with an actual discharge volume of 56.78 megaliters annually. As a small facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, ensuring compliance with water quality standards. The treated effluent is discharged into local waterways that drain into the Meramec River basin, ultimately reaching the Mississippi River. The plant plays a role in protecting the region's aquatic ecosystems by reducing pollutant loads before discharge. Its inland location minimizes direct coastal impacts, but proper treatment remains essential for maintaining the health of the Meramec River watershed.

The plant discharges into local streams that flow into the Meramec River, a major tributary of the Mississippi River. The Meramec River supports diverse aquatic life and is an important recreational resource for the region. Downstream, the Mississippi River carries water to the Gulf of Mexico, where nutrient pollution can contribute to hypoxic zones. The plant's secondary treatment helps reduce organic and nutrient loads, supporting the ecological health of the watershed.
