Abstract

Historically, computing power and software limitations necessitated that only the most significant features of the distribution system are represented. In recent years, advances in hardware and software technologies have provided the ability to include all the pipes in the distribution system. An all-pipes hydraulic model with 157,000 pipes was developed at the Las Vegas Valley Water District (District) utilising a one-to-one relationship between model features and GIS features. Calibration of such large models poses challenges in terms of collecting and handling large amounts of data from various sources, including SCADA, GIS and an enterprise database. This paper presents data integration, processes and tools developed at the District for calibration of a large all-pipes model.
