The North Carolina Department of Environmental Quality (NC DEQ) 319 program, North Carolina State University, City of Burlington, and HydroVault Systems Inc. will be constructing an underground infiltration system at the Alamance County YMCA. This underground infiltration system will structurally support the overlaying ground surface and will be filled a proprietary media that is designed to remove pollutants from stormwater runoff and encourage infiltration. This system will be monitored for water quality, hydrology, and its effects on the adjacent stream. The results from this project will quantify the benefits of this particular underground infiltration system.
