Given the importance of water supply facilities, sometimes in the enemy's sabotage operation, these facilities are targeted as strategic centers, which may lead to serious damage to society and sometimes to security crises. Regarding this issue, in this research, the overall method of combining Risk Analysis and Management for Critical Asset Protection (RAMCAP) and Analytic hierarchy process (AHP) with regard infrastructure of water risk in Tehran was investigated for risk aversion. The present research is an applied research (extension type). In this way, a questionnaire (quantitative) was used to collect and analyze information. The research method is descriptive-analytic. For this purpose, 42 experts were selected as experts. The results indicated that the importance of assets based on the three criteria of economic value, functional value, uniqueness of the Latyan dam and Amirkabir dam is the most valuable assets with values of 1 and 0.92, respectively. Twelve threats were also evaluated, with the highest probability of occurrence in the case of chemical-microbial-nuclear attacks and air and missile attacks based on three criteria: severity of damage, enemy's ability and threat history, respectively, with threat number of 1 and 0.89. The most vulnerable is the Letian dam according to the index of detection capability, target capability index, weakness index (military weapon vulnerability), recovery capability, secondary damage index , Water and life threatening), the combined effect index with a vulnerability of 0.931. The riskiest asset is the Latyan dam with a 0.931 risk number and Amir Kabir dam with a risk of 0.835 against chemical-microbial-nuclear attacks.
