Abstract

Urban cloudburst management may include intentional temporary storage of flood water in parks or other recreational areas. In cities with combined sewers this will expose the population to wastewater and increase the risk of diarrhoeal disease. We present an approach to estimate the risk of diarrhoeal disease after urban flooding of a green area by combining hydraulic modelling, an experimental flood simulation and quantitative microbial risk assessment (QMRA). The method allows the cloudburst manager to reduce unacceptable disease risks during the planning of cloudburst management or on existing facilities.
