scope:

The Engineering Modeling Applications Committee of the American Water Works Association developed this manual. The purpose of this manual is to share the committee's collective experience with distribution system modeling to help educate and communicate the benefits of a model to water utilities and water customers everywhere.

The manual is intended to be a basic-level or primer reference guide to provide new to intermediate modelers with a foundation for, and practical benefits of, water distribution system modeling. The manual takes users through the modeling process from development to system analysis as shown in Figure 1-1. The manual delivers in-depth discussion on

• Model construction and development,

• Field data collection and testing,

• Model calibration,

• Steady-state analysis,

• Extended-period simulation,

• Water quality analysis,

• Storage tank mixing and water age analysis,

• Model maintenance,

• Transient analysis, and

• Advanced modeling applications.

M32 is designed to help modelers use water models as effective tools to plan, design, and operate a water distribution system; maintain acceptable water quality; and reduce both operating costs and water loss within their water distribution systems
