LibreWaterNet, water modelling without the budget gate

Editorial interest 88/100 Selection signal · not a rating of the site

An open, browser-based alternative for drawing, solving, and exchanging EPANET water-network models.

Landing page captured for the 2026-09-07 issue.

Field notes

LibreWaterNet combines a map-based drawing surface with EPANET-compatible file handling and in-browser simulation. Its visible workflow covers network elements from junctions and tanks to pumps and valves, then exposes pressure, flow, water-age, source-tracing, chemical-decay, and energy results. The homepage lists 27 languages and GPL v3+, while noting that .net-file support was reconstructed from examples and should be treated with more caution than .inp import.
