Urban areas face a wide variety of water-related challenges, such as securing sustainable water resources and pluvial flooding measures in light of climate change. For example, there are areas where the risk of flooding is increasing due to the increased frequency of heavy rains, and areas where the risk of water shortages is increasing due to reduced precipitation. In order to solve these issues, this research unit will collaborate with local governments and companies to conduct co-creative research on the advancement of urban water management. Specifically, we investigate effective combined sewer overflow control linked to flood prevention and stormwater runoff control measures, sewer infiltration/inflow during rainy weather, and reclamation technology for wastewater, which is a city's own water source, and its efficient operation and maintenance. Furthermore, we aim to achieve sustainable urban water management by conducting research such as improving the accuracy of fecal pollution predictions after rainfall in urban coastal areas and evaluating the water environment using the Water Environment Soundness Index that contributes not only to water quality management but also to biodiversity conservation. |
