New MS4 Needs Assessment Results Report Now Available

The WEF Stormwater Institute has completed two iterations of the National Municipal Separate Storm Sewer System (MS4) Needs Assessment Survey – the first in 2018 and the second in 2020. The primary objectives of these surveys are

  • to better understand MS4 program challenges,
  • to identify the information and resource needs of MS4 permittees, and
  • to approximate current funding levels and estimated funding needs in the MS4 sector.
