HydroCAD Stormwater Modeling - Since 1986

PC Requirements

Hardware and Software Requirements

Operating System

HydroCAD will run on virtually any PC with Windows 98, ME, NT, 2K, XP, Vista, 7, 8, or 10 including 64-bit systemsDetails here.

Although we do not offer a specific Macintosh edition, customers have reported good results running HydroCAD on a Windows Emulator such as Parallels or WINE.

Hard Disk Space

The HydroCAD software requires approximately 10 MB of hard disk space.  Normal project data consumes minimal disk space (Approximately 10k for a 10-node project).

Windows Compatibility

The HydroCAD installation is an extremely safe process that does not install any files to system folders.  With over 50,000 installations, no conflicts have been reported with any other software or system components.

Video Display

HydroCAD will run on any Windows-compatible display system, with full support for dual-monitor configurations.


HydroCAD supports all Windows printers, including all local, network, USB, JetDirect, and other connections.  Also supports specialized "printer" drivers for plotters, PDF output, etc.

Network Support

The standard HydroCAD program is network-ready.  Although the program should be installed on a local hard drive, it supports license pooling by multiple users.

Distribution Medium

HydroCAD is distributed exclusively by download.  If you need to transport the installation program to another PC, you can save a copy to any portable storage medium, such as a USB drive or writeable CD.  This allows you install on any PC at a later time - even one without internet access.

Internet Access

Internet access is required only for the initial software download and for the optional "Check For Update" function.  Otherwise, HydroCAD can be run on a PC without internet access.

Compatibility With Other Programs

HydroCAD is a stand-alone program that does not require other software (other than the operating system.)

Data can be exported and imported through a number of file formats, allowing the creation of links with terrain modeling software and other data sources.  HydroCAD also supports direct import of watershed data from select CAD systems.
