20 ISSUED: NOV. 2021 In 2021, at our USSTC manufacturing facility in downtown Nashville, we partnered with the Cumberland River Compact to construct three rain gardens in our parking lot. Like many cities, Nashville has a "combined sewer," where both storm and sewer water use the same pipe to go to a treatment facility. During big rains, water overwhelms the system. The excess runoff flows across city streets, collecting contaminants like fuel, pesticides and trash, eventually going into the river. A rain garden is a depression with native plants and soil that absorbs that runoff and provides natural cleaning and filtration before it goes back into the system. It also reduces peak storm flows and river-bank erosion.

Water used in manufacturing absorbs nitrogen and phosphorous from tobacco Treated water from the wetlands returns to the James River. The NTS engineered wetlands remove carbon, phosphorous and nitrogen from the water using native plants and microbes. The wetlands create habitat for native animals and birds.
