Resilience is defined to enhance the ability of the community, planning and readiness to achieve and improve more success in dealing with adverse effects of catastrophes providing the view of repairing and improving the injured community. Resilience of critical infrastructure in the face of disasters, before, during and after a crisis is essential for proper response and recovery. Critical aspects of resilience, such as planning for hazardous situations and engaging with the calculation of infrastructures' interdependence must be understood so that managers can enhance system resilience. Sewage transmission and treatment system is considered as one of the important urban infrastructures. Due to the large volume of available wastewater, uninterrupted operation of the sewerage system for the metropolis of Tehran is really important. This performance in the face of unexpected events is a function of its system resilience. The purpose of the current study is to evaluate the resilience of the wastewater-transmission tunnel infrastructure of Tehran metropolitan to the treatment plant of Firooz Bahram. Also, methods of collecting data are based on library resources and face-to-face interview. Thus, considering the threats of the assets of the sewage transfer tunnel, the effective factors in its resilience are presented from the its literature. Then, with the help of Infrastructure Resilience Assessment Method (IRAM), its localization for the sewage-transmission line to Firooz Bahram treatment plant will be done. The results indicate that the current situation does not have the necessary resilience and a large volume of wastewater enters and damages the urban environment and other infrastructure based on scenarios (resilience costs). At the end to address the issue, the solution "Implementation plan of sewage bypass to Kan River" will be proposed and evaluated to improve the level of resilience. Evaluation of the results for implementation of the improve - resilience strategy (primary and secondary RDR difference) approves positive effect [ABSTRACT FROM AUTHOR] |
