Green Infrastructure for CSO Control in Kansas City, Missouri

Kansas City Water Services Department (WSD) conducted extensive modeling and economic studies of its combined sewer system over the last 5 years, for submittal of its long term control plan to EPA. These studies and recent funding opportunities have provided the impetus for selection of Kansas City as a case study location to demonstrate the efficacy and sustainability of green infrastructure approaches in an urban-core neighborhood served by a combined sewer system. The intent of this project is to compile data and demonstrate the water quality and quantity results from larger scale application of LID or micro-BMP retrofits in a subcatchment.Installed monitoring equipment will measure changes in peak flow, total volume and pollutant mass of storm events and overflows for a two-year period. The project also includes outreach with community-based partners to plan, design, implement, monitor and evaluate green infrastructure acceptance from a socio-economic context. Economic, hydraulic, and water quality modeling is also being done. Results from pre-implementation monitoring and expected modeling outcomes developed to date will be presented.
