Urban storm sewer systems management and life-cycle costing

Urban stormwater infrastructures are the first line of defense from pluvial flooding and play a key role in protecting the environment. These systems are costly to construct and would be even more expensive to replace. Therefore, high priority must be given to maintaining the physical integrity of the assets and preserve the hydraulic capacity of the system. Lack of preventive maintenance usually results in a faster decline in condition, which requires a higher replacement and emergency response costs. Infrastructure management provides a structured approach to the construction, use, and decommissioning of infrastructure assets to optimize service delivery and minimize life-cycle costs. This involves optimizing resource allocation and minimizing total life-cycle cost in different time domains. Furthermore, stormwater systems are geographically distributed, and their performance requirement and deterioration profile are strongly related to their local conditions. In order to find the optimal intervention program, a methodology is necessary that takes into account the costs of intervention, potential risk reduction and improvement in service delivery. Moreover, a methodological framework is required to consider both space and time in the analysis. TO BE CON’T
