Abstract: Recent efforts to maintain efficient water distribution networks have led to the installation of measuring devices for real-time monitoring of flow, water pressure, and water quality factors. Research is being conducted to use this data for accident prediction and efficient maintenance. In this study, water supply factors that influence pipeline risk were identified, and an index for risk assessment was developed by determining the weight of each factor. Through literature review, both domestic and international, key factors included in the risk index calculation were identified, such as pipeline aging assessment, real-time hydraulic and water quality measurements, soil corrosivity, asset management, and water treatment plant quality factors. Within five classification systems, specific sub-factors were selected, and the weight of each factor was determined through a survey of water supply experts. The Analytic Hierarchy Process (AHP) analysis showed that pipeline aging assessment factors, real-time measurement data, water supply asset management, soil corrosivity, and water treatment plant quality factors were the most significant. The water distribution network risk assessment index derived from this study can be used for individual evaluations of each pipeline, district metered area, and administrative region, aiding in prioritizing pipeline replacements and network operations.
