MS4 Awards

Officially titled, the National Municipal Stormwater and Green Infrastructure Awards, this program seeks to inspire municipal separate stormwater sewer programs (MS4s) to seek innovative ways to meet and exceed regulatory requirements.

 

Program Information

MS4-Homepage-Image-800x510.pngThe National Municipal Stormwater and Green Infrastructure Awards program, led by the Water Environment Federation (WEF), was established in 2015 through a cooperative agreement with the U.S. Environmental Protection Agency (EPA) to recognize high-performing regulated Municipal Separate Stormwater Sewer Programs (MS4s).

The objective of this program is to inspire MS4 Phase I and Phase II program leaders to seek innovative ways to meet and exceed regulatory requirements in a manner that is both technically effective as well as financially efficient. Submissions undergo a selection process wherein their submission is reviewed by an expert committee and evaluated in two categories: program management and innovation.

Based on the committee scoring, applicants are designated as Bronze, Silver, or Gold community programs. The high-performing programs(s) of each MS4 Phase within each category will be selected as the category winner. Additionally, the Phase I and Phase II programs with the overall highest score will be honored as the formal winners of the year’s National Municipal Stormwater and Green Infrastructure Awards Program. The Phase I and Phase II winners of each category (i.e. program management, innovation, and overall winner) are traditionally recognized during WEFTEC.
