Water quality impacts public health and is influenced by a wide range of factors, from stagnation and associated loss of disinfectant and formation of disinfection byproducts, to growth of microorganisms (e.g., Legionella), to potential contamination after a chemical spill. Flush...

Resilience analysis of critical infrastructure is inherently complex and requires the integration of diverse geospatial data and disparate models in a cohesive analysis to produce meaningful decision support. Recent updates to the Water Network Tool for Resilience (WNTR) allow in...

Within the field of water distribution system analysis, there is an increasing trend to create open source publicly available software that could be used, replicated, and generalized for a wide range of use cases.  This includes the development of numerical models, resilienc...

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 cus...

The resilience of a drinking water distribution system can be associated with both the hydraulics and water quality of the system. The Water Network Tool for Resilience (WNTR) relied on the water quality component of EPANET 2.2 to track and transport a single species within the d...

A resilience analysis of a water distribution system is greatly enhanced by the integration of up-to-date geospatial data describing the water system, hazards, and surrounding community. The Water Network Tool for Resilience (WNTR), an open-source Python package designed to simul...

This study illustrates the usage of multi-species modeling tool to analyze water quality and evaluate water safety within drinking water distribution system.

FAQ document to provide technical support for EPANET

The U.S. Environmental Protection Agency and Sandia National Laboratories have developed the Water Network Tool for Resilience (WNTR) to quantify resilience of drinking water distribution systems. WNTR is a Python package designed to simulate disaster scenarios and analyze impact...

Drinking water utilities are vulnerable to both human-caused and natural disasters that can impact the system infrastructure and the delivery of potable water to consumers. Resilience analysis can help utilities identify high-risk areas in their system and understand how to bette...

Modeling Water Age in Premise Plumbing Systems

EPANET, EPANET-MSX and the Water Network Tool for Resilience (WNTR) are powerful modeling tools for water distribution system modeling. This presentation highlights a range of work associated with these tools to provide real-world examples of how EPANET and associated tools are u...

The use of EPANET for modeling water age with specific discussions to highlight why determining water age is important, how to interpret results, and provides some best practices using EPANET. The results should be useful to anyone interested in water quality modeling using EPANE...
