CENTER WWTP - Mullensville, West Virginia Wastewater Treatment Plant

CENTER WWTP is a municipal wastewater treatment facility located in Mullensville, Wyoming County, West Virginia. Serving a population of about 1,732, the plant is part of the region's infrastructure for managing domestic wastewater in this Appalachian community. As a US-based plant of this scale, CENTER WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the West Virginia Department of Environmental Protection. These permits set effluent limits to protect water quality in receiving streams. The plant discharges treated effluent into local waterways that ultimately drain into the Gulf of Mexico via the Mississippi River system. The surrounding watershed supports diverse aquatic life and provides drinking water sources for downstream communities.

The plant's treated effluent enters local streams within the Upper Guyandotte River watershed, which flows into the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. This inland location means the discharge affects freshwater ecosystems that support fish populations and provide habitat for amphibians and macroinvertebrates. The Appalachian terrain contributes to sensitive headwater streams that require careful management of nutrient and sediment loads.
