EPANET
The public-domain standard for water distribution modelling — hydraulics and water quality in pressurised networks.
A QGIS plugin that turns the free GIS into a water-network modelling environment for EPANET.

QGIS → Plugins → Manage and Install Plugins → "QGISRed"QGISRed, from the ITA group at Universitat Politècnica de València, brings distribution-network model building into QGIS: digitise or import networks, manage elevations from DEMs, assign demands, detect topology errors, run EPANET simulations and visualise results — with the model stored as GIS layers throughout.
For small utilities and consultancies that already work in QGIS, it assembles a genuinely free modelling stack (QGIS + QGISRed + EPANET) that covers a surprising share of what commercial GIS-integrated packages charge for.
