Notes

Steady state

Solves one loading condition at a time, using the same gradient method EPANET uses. No extended-period (time-varying) simulation.

Not modeled

Tanks, water quality, and pressure-dependent valves (PRV, PSV, FCV) are not supported. A pipe can carry a fixed minor loss, but not a valve whose open/closed status depends on the solved flow.

Saved network

One network is saved automatically in this browser, with no guarantee about preserving data through the preview stage. This is an early preview -- please use it for small and test networks only.

Roadmap

Saving, downloading, and sharing networks between devices are planned. Comments and suggestions are always welcome (see the feedback link above).
