Stormwater Public MeetingThursday, September 26 from 11 a.m. to 1 p.m. at Hodges Library in Room 235-J. This is the 2019 open public comment meeting for the 2019 Annual Stormwater Report. The report is a summary of all campus stormwater events, maintenance and policy changes from the previous fiscal year. This report is published to the State of Tennessee. We will be happy to discuss any aspects of the report, which can include any comments, suggestions or questions the campus population may have.

How to Reduce Pollution in Stormwater Runoff
What is Stormwater?
Stormwater is water runoff during and after a rain storm from streets, construction sites, parking lots, buildings and other areas that goes directly into storm drains and eventually into local streams and rivers. This water can pick up pollutants along the way to these streams and rivers. The University of Tennessee, Knoxville has set up a program that seeks to protect this water from pollutants.
Why are stormwater and sewer systems separate?
Stormwater systems are not treated at the waste water treatment facility. This water flows directly to the streams and rivers. Waste water (sewage) is sent to the waste water treatment facility and cleaned before it is released into the rivers.
Current Structural Best Management Practices (BMPs)
- 8 cisterns, totaling approximately 111,000 gallons of captured and Stormwater to be reused for irrigation. Upon completion of the West Campus Housing Phase 1 this water will also be used to flush toilets and supply cold water forlaundry
- 18 water quality units total throughout campus designed to remove 80% of the Total Suspended Solids (TSS) present in Stormwater.
- Oil water separators are located in the parking garages to filter out hydrocarbons.
- 2 rain gardens are in operation at the Environmental and Landscape Lab and Biosystems Engineering and Soil Science (3100 square feet).
- 37,400 sq. ft. of Permeable pavers serving as an alternative to paving services that allows Stormwater infiltrate instead of running off. On the pedestrian bridge the pavers also act as a detention to capture Stormwater and slow therate of discharge.
- 38 Bio-Retentions structures called Silva Cells are installed beneath street trees, which capture and retain Stormwater for uptake by the trees.
- 2 Green Roofs have been installed covering 11,300 sq. ft.
- 895 feet of Grassed Swale allow infiltration of Stormwater and reduce the peak discharge.
- 7670 feet of vegetated filter strip which slows the overland flow and improves water quality prior to discharging into receiving waters.
- 3 Dry detention basins/vaults used to slow the peak Stormwater discharge.
