WEF Bestows MS4 Stormwater and Green Infrastructure Awards on Leading Municipalities

The Water Environment Federation (WEF; Alexandria, Va.) has recognized leading Municipal Separate Storm Sewer Systems (MS4s) for exceeding regulatory requirements. The National MS4 Stormwater and Green Infrastructure Awards were presented to six high-performing utilities during the Stormwater Congress at WEFTEC® 2016 in New Orleans.

Developed in 2015 through a cooperative agreement between WEF and the U.S. Environmental Protection Agency, the MS4 awards recognize achievement in two categories — innovation and program management. Participating municipalities were classified as either

  • Phase I, consisting of medium or large cities with more than 100,000 customers; or
  • Phase II, covering smaller storm sewer systems outside of heavily populated urban areas.

WEF announced a winner in each classification for both categories and overall for achieving high scores in both categories. The winners of the second annual National MS4 Stormwater and Green Infrastructure Awards, chosen by a steering committee of leading water experts, were:

Overall Highest Scores

  • Phase I –  Santa Clara Valley Urban Runoff Pollution Prevention Program, Calif.
  • Phase II –  Capitol Region Watershed District, Minn.

  • Phase II –  City of Auburn, Ala.
