TravisCI Coverage Status Documentation Status Downloads

The Water Network Tool for Resilience (WNTR) is a Python package designed to simulate and analyze resilience of water distribution networks. The software includes capability to:

  • Generate water network models
  • Modify network structure and operations
  • Add disruptive events including pipe leaks
  • Add response/repair strategies
  • Simulate pressure dependent demand and demand-driven hydraulics
  • Simulate water quality
  • Evaluate resilience
  • Visualize results

For more information, go to http://wntr.readthedocs.io

Installation

The latest release of WNTR can be installed from PyPI using the command pip install wntr. Additional instructions are available at https://wntr.readthedocs.io/en/latest/installation.html.
