Impact/Purpose:
Drinking water systems face multiple challenges, including aging infrastructure, water quality concerns, uncertainty in supply and demand, natural disasters, environmental emergencies, 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. The Water Network Tool for Resilience (WNTR) is a Python package allowing for end-to-end evaluation of drinking water infrastructure resilience to disasters. The software improves upon EPANET's capabilities by fully integrating hydraulic and water quality simulation, damage estimates and response actions, and resilience metrics into a single platform. This tool is important for drinking water systems around the world who want to better understand how their water systems can withstand natural disasters like earthquakes, floods, and power outages.
Description:
Resilience analysis of critical infrastructure is inherently complex and requires the integration of diverse data and disparate models in a cohesive analysis to produce meaningful decision support. In this presentation, we discuss recent updates to the Water Network Tool for Resilience (WNTR) to help support data integration and co-simulation. This includes the ability to integrate geospatial data from geographic information systems (GIS) and use custom simulation options for greater control of stop conditions and output. These updates will be discussed along with applications that are using these features. The GIS capabilities facilitate a wide range of model integration and analysis options and is currently being used to enhance water network model development in Puerto Rico. The simulation options facilitate integration with third party simulation and optimization tools, such as Sandia’s Microgrid Design Toolkit which is currently being used to define design objectives for water and power systems under different threat conditions. Future development of WNTR will continue supporting features to enhance integration and support diverse analysis options.
