ABSTRACT: Water facilities are among basic infrastructures in any country. In case of lack of preparedness and preventive and predictive programs and suitable staff training, any potential damage to these facilities may result in crisis and have adverse health, political and social impacts. Water transfer and distribution systems are one of the main elements in water supply facilities which are subject to qualitative and quantitative risks resulting from dangers and natural threats (earthquake and floods) as well as man-made risks (e.g. unstable flow, corrosion, high pressure, executive operation, etc.).Accidents in water supply networks especially water transmission lines annually create considerable damage for organizations. Negligence to potential dangers and determining vulnerability and risk in design, utilization and maintenance stages of facilities may create irreversible costs for operation of the water utilities, side facilities and the environment. Using methods based on hierarchical series and fuzzy inference system, risk analysis in water transmission system from Koot Amir Water Treatment Plant to Mahshahr Special Economic Zone was done. This system is composed of a collection of pipe lines, canals, and pumping stations, and supplies water needs of Mahshahr Special Economic Zone as well as drinking water of some cities and towns on its path, and it is considerably important economically and socially.
