Impact/Purpose:
Drinking water utilities are among the most critical civil infrastructure and must be prepared to withstand or quickly recover from any disruptive incident. With increasing threats to drinking water systems, including natural disasters and other emergencies, utilities need to evaluate and strengthen their overall resilience. The presentation introduces the Water Network Tool for Resilience (WNTR) tool which builds upon EPANET capabilities to analyze the resilience of water distribution systems to disruptive incidents, and can be used as a component of a comprehensive risk and resilience assessment.
Description:
Water distribution systems are among the most critical civil infrastructure and must be prepared to withstand or quickly recover from any disruptive incident. With increasing threats to drinking water systems, including natural disasters, water shortages, power outages, bioterrorism, and other emergencies, utilities need to evaluate and strengthen their overall resilience. The U.S. Environmental Protection Agency and Sandia National Laboratories have developed the Water Network Tool for Resilience (WNTR) to evaluate the resilience of water distribution systems to disruptive incidents. WNTR incorporates disaster data and utility response and mitigation strategies to predict possible outcomes of various resilience scenarios over time.
