Vulnerability Self Assessment Tool (VSAT)

Overview

VSAT is a risk   assessment software tool for water, wastewater, and combined utilities   of all sizes. The tool assists drinking water and wastewater owners and   operators in performing security threats and natural hazards risk   assessments, as well as updating utility Emergency Response Plans. EPA,   in collaboration with Water Sector partners, has updated VSAT to be   consistent with the 2007 Risk Analysis and Management for Critical Asset   Protection framework. The upgraded tool includes a new user-interface,   an enhanced natural disaster threat assessment process, and a revised   risk assessment approach. VSAT 5.0 software will provide the following   benefits:

 
• An intuitive process with   improved navigation and   enhanced work tracking features;
 
• An improved analytical approach that will make   consequence, vulnerability, and likelihood of occurrence assessments of   threats more transparent; and
 
• A natural disaster assessment process supported   by historical information to enable likelihood determinations.
