We created this from a fork of Placemark[0] to give water utilities an alternative choice to the big players, Autodesk and Bentley.

The majority of commercial modeling software uses the U.S. EPA's engine and adds a nicer interface. They all fork the engine to add enhancements but don't contribute back.

This is our attempt to create an open-source alternative for water engineers and contribute back to the core engine at the same time.

You can check out the source code on GitHub[1].
