SOFTWARE DOWNLOADS
EPANET is public domain software developed by USEPA. EPANET can perform steady-state and extended period simulations for networks of junctions, pipes, pumps, valves, and storage structures, calculating flow of water, pressures, tank elevations, concentration of chemical species, water age, and source tracing.
Customize EPANET
Most commercial water distribution modeling applications leverage the EPANET engine through the available Programmer's Toolkit, a dynamic link library (DLL) of functions that allow developers to customize EPANET's computational engine for their own specific needs.
Use the Programmer's Toolkit to develop specialized applications that EPANET does not support in its standard form, such as optimization or automated calibration, routines that require running many network analyses as selected input parameters are iteratively modified (i.e. fire flow or criticality analyses), or to create CAD and GIS-integrated models.
Technical support:
There is no formal technical support offered by USEPA, but you can register for EPANET.com forums to find quick answers to your EPANET modeling questions. For your reference you can also download a list of EPANET updates and bug fixes.
Developed by Haestad Methods, Inc. in 1996, WaterCAD is the most popular commercial water distribution modeling package in the industry. Recognized all over the world for its ease of use and convenient scenario management features, WaterCAD includes powerful hydraulic and water quality modeling tools in a modern stand-alone GIS-type interface.
An AutoCAD-based interface option is also available, and with Bentley's acquisition of Haestad Methods in 2004, a new MicroStation-based interface was added to the family.
