Field notes
Libre WaterNet places a drawing surface over a browser-loaded OWA-EPANET engine, allowing users to construct a mapped pipe network and exchange it through EPANET’s .inp format. The project also uses JSON for scenarios, profile paths, map tiles, and other context that the interchange format cannot hold. Its stated validation includes 2,425 head comparisons across 25 reporting steps for EPA’s Net3 example, with agreement to 0.005 ft.
