In partnership with the Awwa Research Foundation (AwwaRF) and Sandia National Laboratories, the Environmental Protection Agency (EPA) undertook a program in 2000 to improve security at water utilities across the United States . RAM-WTM was designed to assist large water utilities and security professionals in assessing the risks from malevolent threats. Through a systematic, thorough evaluation of the water utility operations, a prioritized plan for consequence mitigation, security upgrades, modifications to operational procedures, and/or policy changes can be developed to mitigate identified risks. Following the methodology will aid in describing critical facilities and assets to protect, identifying system vulnerabilities, and determining the level of protection to which the security system should be designed. The goal of RAM-WTM is to provide a plan for balanced risk reduction measures by appropriately applying valuable water utility resources.
In 2003, in partnership with AwwaRF, a streamlined version of RAM-WTM was developed to provide guidance for small and medium water utilities. The methodology is a condensed version of RAM-WTM and was designed to be less computational intensive as the methodology applied to the large water utilities. The streamlined version of RAM-WTM was intended to assist those responsible for conducting an assessment at small and medium water utilities in understanding and applying security concepts appropriately.
