U.S. EPA's Water Network Tool for Resilience August 23, 2024 By Katelyn McLaughlin Emergency Response, Water Treatment Water Network Tool for Resilience, water resilience, WNTR 0 Researchers from U.S. EPA and Sandia National Laboratories developed the Water Network Tool for Resilience (WNTR), a "comprehensive scientific software package to help assess a drinking water systems’ resilience to natural disasters. The software improves upon already available capabilities by fully integrating hydraulic and water quality simulation, damage estimates and response actions, and resilience metrics into a single platform. The software is available as an open-source software package and can be applied to a wide range of disruptive incidents and repair strategies." Utilities can incorporate WNTR into their existing systems by simulating various scenarios, like power outages or critical pipe breaks, to assess impacts and identify potential repair strategies. WNTR can be utilized in the development of Emergency Response Plans by helping to evaluate and prioritize preparedness strategies and response actions to enhance resilience of the utility. It can also be used to assist in meeting legal requirements, such as those set out in America’s Water Infrastructure Act of 2018, by identifying system vulnerabilities and determining mitigation measures. The Water Network Tool for Resilience (WNTR) integrates several key features: Hydraulic and Water Quality Simulation: WNTR combines hydraulic simulations with water quality analysis to understand how water moves and changes within the distribution system. Damage Estimates and Response Actions: It estimates potential damages from disasters, helps utilities to understand how infrastructure damage might occur over time, and evaluates the effectiveness of response actions. Resilience Metrics: The tool includes metrics to assess the resilience of water systems under various scenarios. Compatibility with EPANET: WNTR is compatible with EPANET, a widely used software for modeling water distribution systems, enhancing its utility and accuracy.
