Bentley WaterCAD V8i

Water Distribution Modeling and Management



WaterCAD is a robust and comprehensive water distribution modeling program that can be customized with additional modeling platforms and modules as your modeling requirements grow.

Included and Available Interfaces

WaterCAD includes, out-of-the-box, two interoperable platforms, letting you choose the environment that best fits your skills and modeling requirements.

1. Windows stand-alone: Enjoy unparalleled ease-of-use and versatility, multiple background support, advanced thematic mapping, powerful element symbology features, and conversion utilities from CAD, GIS, and databases.

2. Run in MicroStation: Support for MicroStation is included at no additional cost; seamlessly use every WaterCAD feature within MicroStation's powerful engineering design and geospatial environment.

AutoCAD users:
 WaterCAD's award-winning AutoCAD interface is available as an add-on feature so you can directly leverage AutoCAD's drafting tools with your WaterCAD models. 

ArcGIS users: Upgrade your WaterCAD license to WaterGEMS to unlock the impressive ArcGIS integration features. WaterGEMS also includes a stand-alone environment, runs in MicroStation and AutoCAD, and includes all WaterCAD add-on modules.

WaterCAD Add-On Modules

Enhance your productivity with specialized modules for calibration, optimized design, network simplification, and water security.

Model calibration | Darwin Calibrator 
A calibrated model empowers you to make reliable decisions based on results that truly reflect your real world system. Darwin Calibrator supports the entire calibration process significantly reducing manual trial-and-error work.


Optimized design | Darwin Designer 
Sound design and rehabilitation for water infrastructure often involves time-consuming workflows. Darwin Designer evaluates thousands of alternatives that meet your hydraulic requirements, recommending those that minimize capital investment.


Network simplification | Skelebrator 
Simplifying or skeletonizing your model to different levels of complexity allows you to efficiently tackle a wider range of engineering applications. Skelebrator helps you to remove network complexity while maintaining network connectivity and hydraulic equivalence.


SCADA integration | SCADAConnect
Use SCADAConnect to link WaterGEMS or WaterCAD with your Supervisory, Control, and Data Acquisition (SCADA) system, creating real-time system simulators that boost your confidence in models as reliable decision-support tools.



SCADAConnect Module
Seamless integration of SCADA and hydraulic modeling

Use SCADAConnect to link WaterGEMS or WaterCAD with your Supervisory, Control, and Data Acquisition (SCADA) system, creating real-time system simulators that boost your confidence in models as reliable decision-support tools.

With SCADAConnect you will:

Start simple and add functionality as you need it

WaterCAD is an affordable water modeling solution that grows with your hydraulic modeling needs. Out of the box, WaterCAD gives you robust hydraulic, fire flow, water quality, criticality, energy, and capital cost analysis features—with the possibility of adding advanced GA calibration, automated design, skeletonization, and SCADA and ArcGIS integration features.

Find more time for engineering

Time-saving features help you streamline data entry and leave you more time for engineering and decision-making. Use flexible tabular reports, maintain your own engineering attribute libraries for faster data input, create persistent multi-parameter queries, and manage engineering units on the fly.

Jumpstart your model using your existing data

If you already have CAD drawings, GIS files, or external databases for your water system, you are only a few clicks away from having a WaterCAD model of your network. Geospatial modules help you allocate demands and elevations automatically, while easy to use wizards help you extract data and topology from your geospatial data sets, SCADA, and external databases.

Share your work with everyone

Use the included MicroStation integration features to generate smart PDFs to share your modeling results with anyone with Acrobat Reader, or post your model drawings to the Web using MicroStation’s Google Earth Tools. You can also hand your WaterCAD model to a WaterGEMS user, or export it to EPANET to collaborate with your peers.

Be prepared to respond

WaterCAD helps you be more responsive to emergencies and complaints. Simulate contamination, fires flow scenarios, pipe breaks, and power outages and find the best operational strategies to address them. Use the new Criticality Analysis Center to determine critical network segments to prioritize rehabilitation investment.

Organize your scenarios for better decision making

Use WaterCAD’s Scenario Control Center to organize an unlimited number of design, water demand, operation, and network topology scenarios, create solution scenarios on the fly, and compare results for better decision-making support.

Robust hydraulics and comprehensive cost assessment

WaterCAD accurately models the operation of variable-speed pumps, pressure-dependant demands, rule-based controls, and hydrants to emulate the most complex operational strategies. Develop energy-saving strategies using WaterCAD to determine the cost of operating your pumps using any energy tariff.

Understand results easily

Spot operational bottlenecks with animated 3D graphs of time-variable data, use property-based color coding, element symbology and annotation, find low pressure zones or poor chlorine concentration areas by generating contour maps, plot multiple attributes for a series of elements on the same profile, and analyze tabular data with full unit control, built-in filtering, sorting, and statistical analysis.
