PURPOSE OF THE MANUAL

This manual (M32) was developed by the Engineering Modeling Applications Committee of the American Water Works Association (AWWA). The purpose of this manual is to share collective expertise on distribution system modeling so that it is better understood and applied more effectively to benefit water utilities and water customers everywhere. The manual is intended to be a basic level or primer reference manual to provide new to intermediate modelers with a basic foundation for water distribution system modeling. The manual is intended to take users through the modeling process from model development to system analysis as shown in Figure 1-1. The manual has in-depth discussion on

• Model construction and development

• Field data collection and testing

• Model calibration

• Steady-state analysis

• Extended-period simulation

• Water quality analysis

• Transient analysis

• Tank mixing analysis

M32 is designed to help moders use water models as effective tools to plan, design, operate, and improve water quality within their water distribution sytems.
