Stormwater Management


Williamson County has developed a program to manage the quality of stormwater runoff from the stormwater drainage system. The program will focus on the following:
  • Construction site stormwater runoff control
  • Good housekeeping for county operations
  • Illicit discharge detection and elimination
  • Pollution prevention for county operations
  • Post-construction stormwater management
  • Public education and outreach
  • Public involvement / participation

Williamson County is one of more than 85 Tennessee communities that submitted a Notice of Intent (NOI) application to the Tennessee Department of Environment and Conservation (TDEC) for coverage under the Tennessee Phase II MS4 general storm water permit.
