Gilmore Avenue Green Infrastructure Reduces CSO Flows While Improving Water Quality

The Gilmore Avenue Sewer Separation Project is part of Omaha’s effort to reduce combined sewer overflows. Green infrastructure was studied to see how it might reduce discharges into the parts of the sewer system not slated for replacement or upgrade. As a result, the Gilmore Avenue watershed now incorporates dry detention with a constructed wetland, bioretention, and rain gardens. Green infrastructure was also incorporated on a road right of way that receives significant discharges of salts and deicing chemicals; the project not only reduces peak runoff but also improves water quality by treating salts and heavy metals.
