Webinar | EPA Tools & Resources Webinar Water Network Tool for Resilience (WNTR)

September 16, 2020 @ 12:00 pm - 1:00 pm

Drinking water utilities face multiple challenges—including aging infrastructure, water quality concerns, pipe breaks, uncertainty in supply and demand, natural disasters, environmental emergencies and terrorist attacks. All of these have the potential to disrupt service to customers and damage critical infrastructure. Increasing resilience to these types of hazards is essential to improving water security. Simulation and analysis tools can help water utilities predict how their system will respond to expected and unexpected incidents and help inform decisions to make water distribution systems more resilient over time. EPA, in partnership with Sandia National Laboratories, developed the Water Network Tool for Resilience (WNTR), an open source Python package, to integrate critical aspects of resilience modeling for water distribution networks into a single software framework. WNTR can help water utilities investigate the resilience of their water systems to a wide range of hazardous scenarios and evaluate emergency response actions and long-term resilience‐enhancing strategies. The software estimates potential damages from disaster scenarios; predicts how damage to infrastructure would occur over time; evaluates preparedness strategies; prioritizes response actions; and identifies worse case scenarios, efficient repair strategies, and best practices for maintenance and operations. This webinar will provide an overview of WNTR along with a few case study applications.
