Water modelling software for civil engineers

Every water model.
On a real map.

CIVILDRAW is a family of four desktop applications for water distribution, stormwater and sewers, rivers and floodplains, and watershed hydrology. Each one builds the model on the map, runs the analysis and shows the results where the water actually goes.

  • 1
    Draw it. Build the model over imagery, terrain and your GIS and CAD layers.
  • 2
    Run it. Run the analysis without leaving the map.
  • 3
    See it. Pressures, flows, depths and floods, on the map and in reports.

Four products. One family.

Choose the one for your work, or take all four as CIVILDRAW Hydro.

Early access

Every pipe. Every pressure. On the map.

Model pressurised water distribution systems on a real map: pipes, pumps, tanks, valves, pressures and water quality.

Explore CIVILDRAW Water
Early access

From rainfall to outfall.

Design and analyse stormwater and sewer systems: networks, inlets, ponds, low-impact development and runoff.

Explore CIVILDRAW Storm
In development

See the flood before it comes.

River and floodplain modelling, 1D and 2D, on the map: reaches, cross sections, 2D areas, depth and arrival-time maps.

Explore CIVILDRAW Flood
In development

From raindrop to river.

Watershed hydrology on the map: subbasins, reaches and rainfall-to-runoff, built from your terrain.

Explore CIVILDRAW Basin
All four on one licence: CIVILDRAW Hydro. Every water model. One map.

What every product shares

A real map

Aerial imagery, street maps and terrain under every model, in the coordinate system your project uses.

Your GIS and CAD data

Bring in shapefiles, GeoPackages, rasters and drawings as layers, and build models from them.

2D and 3D

Work in plan, then tilt into 3D to see the network and the ground together.

Reports

Results to PDF and Excel, ready for review and submission.

Built on trusted engines

CIVILDRAW does not reinvent the hydraulics engineers already rely on. Water and Storm include their engines; Flood and Basin work with the free engines you install yourself. Your existing models come straight in.

  • CIVILDRAW WaterRuns the EPANET 2 engine, included.
  • CIVILDRAW StormRuns the EPA SWMM 5 engine, included.
  • CIVILDRAW FloodOpens, edits and saves HEC-RAS project files, and runs HEC-RAS installed on your computer.
  • CIVILDRAW BasinOpens, edits and saves HEC-HMS project files, and runs HEC-HMS installed on your computer.

HEC-RAS and HEC-HMS are developed by the U.S. Army Corps of Engineers Hydrologic Engineering Center. EPA SWMM and EPANET are developed by the U.S. Environmental Protection Agency; OWA-EPANET is maintained by Open Water Analytics. CIVILDRAW is an independent product and is not affiliated with, sponsored by or endorsed by USACE, HEC, EPA or Open Water Analytics.
