LibreWaterNet: water-network modelling in the browser
An open, community-owned tool for drawing, solving, and exchanging water-network models without an account.
Field notes
LibreWaterNet uses the EPANET engine to model pipe networks drawn on a map, with support for importing and exporting EPANET files. The homepage lists fire-flow and pump-energy calculations, scenarios, tables, and a profile view, and identifies an example called EPA’s Net3 with 92 junctions. It also states that the interface is available in 27 languages and is released under GPL v3+. The project is soliciting bug reports, wish lists, and governance advice while its nonprofit structure remains undecided.
