Abstract
Water and wastewater infrastructures are crucial assets constantly exposed to various disasters, prompting researchers to prioritize strategies for improving their resilience. Given Tehran's significance as Iran's capital and the heightened vulnerability of its water transmission pipelines to seismic events, along with the looming threat of major earthquakes, this study investigates existing research on resilience. The aim is to pinpoint essential strategies for fortifying the resilience of Tehran's water supply infrastructure against earthquakes. Through semi-structured interviews and a survey, we refined criteria and tested research hypotheses based on insights from water and wastewater construction sector experts. The consensus among experts confirms the availability of practical solutions for enhancing the resilience of water supply pipelines against earthquakes. These solutions revolve around enhancements to pipe material, thickness, fittings, and implementation strategies.
