MS4 Awards

The National Municipal Stormwater and Green Infrastructure Program for Municipal Separate Stormwater Sewer Programs (MS4s) aims to recognize high-performing communities that meet and exceed regulatory requirements in a manner that is both technically effective and financially efficient. Led by the Water Environment Federation (WEF), the program was 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-performing programs(s) in Phase I and Phase II programs within each category will be honored at the 97th Annual WEFTEC Exhibition and Conference which will be held in New Orleans, Louisiana, October, 5 - 9, 2024.
