MS4 Awards

The National Municipal Stormwater and Green Infrastructure Program for Municipal Separate Storm Sewer Systems (MS4) aims to recognize high-performing communities that meet and exceed regulatory requirements in a technically effective and financially efficient manner. Led by the Water Environment Federation (WEF), the awards were established in 2015 through a cooperative agreement with the U.S. Environmental Protection Agency (EPA).

Submissions undergo a thorough review by an expert committee and are evaluated in two categories: program management and innovation.  The three highest-scoring programs in Phase I and II for both categories will be honored at WEFTEC 2025.  If your organization cannot attend WEFTEC, we will make other arrangements with you to present your award.

Please email Lisa Deason, Senior Manager, Community Engagement, with questions at ldeason@wef.org or by text/call at 706-681-7091.

The Award Application Period opens June 27, 2025, and will close on August 31, 2025
