Storm Water Management
Williamson County Storm Water Management Plan
This Storm Water Management Plan (SWMP) (PDF) was developed to prevent pollution from storm drainage systems to the maximum extent practicable, with control measures being phased in during the 5-year permit term. The SWMP addresses six minimum control measures (MCMs):
- Public Education and Outreach on Storm Water Impacts
- Illicit Discharge Detection
- Construction Site Storm Water Runoff Control
- Post-Construction Storm Water Management in New Development and Redevelopment
- Pollution Prevention/Good Housekeeping for Community Operations
- Industrial Stormwater Sources (not applicable to Level 2 MS4s)
The Texas Pollutant Discharge Elimination System (TPDES) Permit requirements apply only to the portions of unincorporated Williamson County that are identified as urbanized areas. There are approximately 43 non-contiguous urbanized areas in unincorporated Williamson County. These areas are identified based on data in the 2010 U.S. Census map.

How to Help
Law enforcement officials need your help in fighting environmental crime. Citizens can take an active role in stopping illegal dumping by following the suggestions listed below:
- Always dispose of your own litter properly;
- Spread the word to friends and neighbors that illegal dumping is a crime;
- Do not transport unsecured debris in the back of a vehicle - always use a tarp or other cover;
- Organize volunteer cleanups of illegal dumpsites - people are less likely to litter in clean areas;
- Do not pay roofing or other contractors until they present you with a landfill receipt showing that your waste was properly disposed;
- Report illegal dumping in unincorporated areas to: Williamson County Road and Bridge, phone: 512-943-3330.
