Greening CSO Plans: Planning and Modeling Green Infrastructure for Combined Sewer Overflow (CSO) Control

Learn more about EPA’s recently released “Greening CSO Plans: Planning and Modeling Green Infrastructure for Combined Sewer Overflow (CSO) Control,” which will provide municipalities and sewer authorities with tools to help quantify green infrastructure contributions to a CSO control plan. Communities with combined sewers often view green infrastructure as an attractive way to reduce stormwater flows going into their sewer system, thus helping to reduce capital and operational costs at publicly owned treatment works.

Greening CSO Plans will help communities make cost-effective decisions to maximize water quality benefits. This resource explains how to use modeling tools such as EPA’s Storm Water Management Model to optimize different combinations of grey and green infrastructure to reduce both sewer overflow volume and number of overflow events. See Greening CSO Plans: Planning and Modeling Green Infrastructure for Combined Sewer Overflow Control for more information.

Alice Gilliland received her Ph.D. from the GA Institute of Technology in Earth and Atmospheric Sciences. Dr. Gilliland currently serves as an Acting Division Director in the ORD National Risk Management Research Laboratory. Her research background primarily focused on environmental fate and transport modeling, source characterization, model evaluation and sensitivity analysis. Dr. Gilliland is also the lead for ORD’s Green Infrastructure (GI) research. As a key area of the SSWR research program, it involves a number of community partnerships studying the effectiveness of various GI pilots and the development of stormwater and watershed management tools.
