Field notes
The editor stores projects as JSON alongside EPANET .inp files, preserving scenarios, profile paths, map context, multiline labels, and coordinates that the interchange format cannot represent. Its calculations rely on a 679 KB on-demand OWA-EPANET 2.3.5 build, while the site's own solver is limited to a single instant of pressures and flows. The project reports checking extended simulation against EPA's Net3 example across 2,425 head comparisons and 25 reporting steps.
