RINER STP - Secondary Wastewater Treatment Plant in Riner, Virginia

RINER STP is a municipal wastewater treatment plant located in Riner, Montgomery County, Virginia. Serving a small population of 331 residents, the facility provides secondary treatment to meet state and federal water quality standards. The plant is situated in the rural Appalachian region, where treatment infrastructure supports local communities and protects downstream water resources. The plant operates under the U.S. Clean Water Act, administered by the Virginia Department of Environmental Quality (DEQ). Secondary treatment is the standard for small agglomerations in the United States, ensuring removal of organic matter and suspended solids. With a designed capacity of 378.54 cubic meters per day and a current discharge volume of 83.28, the plant has reserve capacity for future growth. Treated effluent from RINER STP flows into local streams that drain into the New River watershed, part of the Ohio River basin. The New River is ecologically significant, supporting diverse aquatic life and serving as a corridor for migratory fish. The plant's discharge is regulated to prevent nutrient enrichment and protect downstream ecosystems.

RINER STP discharges into tributaries of the New River, which flows northward through Virginia and West Virginia before joining the Kanawha River and ultimately the Ohio River. The New River watershed supports diverse aquatic species, including several endemic fish and mussel species. The plant's secondary treatment helps maintain water quality in this ecologically sensitive region, preventing excessive nutrient loading and protecting downstream habitats.
