Hickory Flats Jonesville Wastewater Treatment Plant, Lee County, Virginia

Hickory Flats Jonesville is a municipal wastewater treatment plant located in Lee County, Virginia, serving a population of approximately 7,400. The plant operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal facilities of this scale. As a secondary treatment plant, it uses biological processes to remove organic matter and suspended solids, meeting national effluent standards before discharge. The plant has a designed capacity of 3,028 cubic meters per day and currently handles an average daily flow of 757 cubic meters, indicating operational headroom. It is situated inland, more than 50 kilometers from the coast, and discharges treated wastewater into local streams that ultimately feed into the Tennessee River watershed. This region is part of the broader Mississippi River basin, which drains into the Gulf of Mexico. The receiving water bodies support diverse aquatic life and are important for local ecosystems. The plant's secondary treatment helps protect water quality in these streams, reducing nutrient loads and preventing eutrophication downstream. Its operation is subject to National Pollutant Discharge Elimination System (NPDES) permits, ensuring compliance with federal and state water quality standards.

The plant discharges into local streams within the Tennessee River watershed, which flows into the Ohio River and then the Mississippi River, eventually reaching the Gulf of Mexico. This inland system supports diverse aquatic habitats and is a critical migratory corridor for fish and other species. The secondary treatment process reduces organic pollutants and nutrients, helping to maintain the ecological balance of these waterways and prevent algal blooms downstream.
