Abstract

Water distribution networks are critical infrastructures that ensure the reliable supply of water for domestic, industrial, and commercial use. Disruptions in these networks can have severe consequences for public health, economic stability, and national security. Therefore, assessing and enhancing the resilience of water supply systems is essential to mitigate risks and ensure continuous operation during crises.

This study proposes a hybrid resilience model for urban water distribution networks by integrating the ERASMUS and IRAM frameworks. The model was applied to evaluate the resilience of a critical zone within the water supply network of Babol City. Assets in the study area were categorized into reservoirs and pipelines, and potential disruption scenarios were identified through expert consultations with passive defense specialists and staff from Mazandaran Water and Wastewater Company.



Key evaluation parameters and indicators were defined to assess the current resilience level (RDR) of the network. The analysis revealed significant vulnerabilities, including high non-revenue water losses and aging infrastructure, which increase susceptibility to threats such as asset deterioration and pressure fluctuations. Field inspections were conducted to validate the findings and propose targeted solutions for improving the network’s capacity and sub-capacities.

Post-implementation reassessment demonstrated a measurable improvement in the zone’s resilience, highlighting the effectiveness of the proposed model. This study underscores the importance of adopting a combined resilience approach to enhance the robustness of urban water supply networks and ensure their reliability during emergencies.
