EPANET Services

EPANET is a free software published by the U.S. EPA.  It has been around for many years but has not been updated since 2008.  Still, it is one of the standards in hydraulic modeling of potable water distribution networks.

Many commercial software modeling packages are based on EPANET’s hydraulic engine.  This is good for utilities since they may some day want to move from EPANET to a commercial package or from one commercial package to another.  Using the free EPANET software is a good place to start for small utilities wishing to incorporate hydraulic modeling into their master planning or operational planning efforts.

We can help you get started with an EPANET model.  We can build it from CAD, GIS, paper maps, PDFs of paper maps etc.  Once you find that you desire more tools for modeling, you can then import your EPANET model into a commercial software.

Worried about your EPANET model getting out of sync with your GIS?  No problem, we don’t just build your model and then abandon you.  We can set up a periodic maintenance program where we update and validate your model at an interval that makes sense to your operation.

Need your model calibrated?  We can help with that too.  Let’s start with the field data you already have and then determine how much more (if any) is needed to establish a good confidence level in your model.  If gathering more field data is warranted, let us help you plan an efficient strategy to gather the data and get it done correctly.  Once the data is gathered, we will apply it to your model and adjust roughness values and point out locations in your system that may have open boundary valves or other conditions that are causing the model to diverge from reality.
