Water Network Tool for Resilience (WNTR) User Manual


Klise, K. A., D. Moriarty, M. L. Bynum, R. MURRAY, J. BURKHARDT, AND T. M. HAXTON. Water Network Tool for Resilience (WNTR) User Manual. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-17/264, 2017.


Drinking water systems face multiple challenges, including aging infrastructure, water quality concerns, uncertainty in supply and demand, natural disasters, environmental emergencies, and cyber and terrorist attacks. All of these have the potential to disrupt a large portion of a water system causing damage to infrastructure and outages to customers. Increasing resilience to these types of hazards is essential to improving water security. As one of the United States (US) sixteen critical infrastructure sectors, drinking water is a national priority. The Water Network Tool for Resilience (WNTR) is a Python package designed to simulate and analyze resilience of water distribution networks. WNTR has an application programming interface (API) that is flexible and allows for changes to the network structure and operations, along with simulation of disruptive incidents and recovery actions.
