WaterCAD V8i is a powerful hydraulic modeling software designed for analyzing water distribution systems, including pipes, pumps, tanks, and valves. It offers a user-friendly interface that allows for the easy layout of networks, simulation of scenarios, and analysis of hydraulic parameters like pressure and velocity.
Downloading a is only the first step. To actually learn the software:
A municipal water utility runs Darwin Scheduler on their three-pump station. The optimization identifies a pump sequencing schedule reducing energy consumption by 22% while maintaining required tank levels and system pressures — an annual savings of $85,000.

Real-world water networks do not operate in a steady state. Water use spikes in the morning and evening and drops significantly overnight. An Extended Period Simulation (EPS) models these changes over a 24-hour cycle. Step 5.1: Creating a Diurnal Demand Pattern Navigate to . Right-click Hydraulic and select New . Define a 24-hour pattern with multipliers. For instance: 02:00 AM = 0.4 (Low usage) 08:00 AM = 1.8 (Morning peak) 12:00 PM = 1.0 (Average usage) 07:00 PM = 2.0 (Evening peak)
To get in-depth knowledge and practice files, accessing specialized training materials is recommended. You can search for the following resources online:
Go to to set your preferred system of units (e.g., SI or US Customary). 2. Layout the Network WaterCAD V8i is a powerful hydraulic modeling software
The official Bentley Communities website hosts numerous learning resources:
Bentley hosts an extensive library of PDFs directly within the software’s help menu. To access it:
Before diving into the tutorials, it is important to note that while Bentley has moved on to , many utility companies, government agencies, and consulting firms still rely on the V8i (SELECTseries) version. V8i is stable, requires less computing power, and has a user interface that many veteran engineers prefer. To actually learn the software: A municipal water
A training course description notes that students begin with steady-state fundamentals before advancing to more complex scenarios.
