This paper explores the specific technical challenges to both engineer and simulation tool through
the experience of the Portland Water Bureau and Advantica Stoner. Portland maintains a model
of more than 30,000 elements, but the striking feature is the inclusion of over 600 pressure
regulators supplying 165 pressure zones. Understanding the real system's behavior is quite
difficult, so a hydraulic model is a great operational and planning aid. However, simulating a
system with this degree of pressure regulation presents challenges to current modeling
technology. The challenge was attacked from various angles: field and bench testing;
examination and adjustment of how facilities are represented in the model; and enhancement of
the simulator. The experiences dealing with this complex system are discussed. Modeled
behavior and expected behavior are compared, and a summary of bench test results on the
pressure regulators in use is presented. Includes figures.
