CONTROLLING CSO DISCHARGE WITH LOW IMPACT DEVELOPMENT
eDesign Dynamics and a team of economists developed a Rapid Assessment Method (RAM) for gauging the feasibility and cost effectiveness of Low Impact Development (LID) as a means of reducing the frequency of combined sewer discharges in New York City.
The RAM was driven by existing data sources and related the phased deployment of LID technologies such as green roofs, porous pavement, and rainwater harvesting within a CSO shed to a reduction in the volume of combined sewage discharged. Life cycle analysis was used to compare LID technologies to their respective, conventional alternatives. Policy options involving private public partnerships were also developed.
