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.

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

Award Application Period opens June 27, 2025 and will close on August 29, 2025
