Abstract

It is well known that internal water pressure, including pressure transients, in water supply networks is a major contributing factor in many pipe failures. Reliable prediction of pipe failures needs accurate information about critical contributing factors such as internal water pressure. This paper reports on a numerical study of transient pressure development following a pressure-monitoring program. Two large water supply network sections were considered, and pressure transient hydraulic models were developed using a relevant computer program. Extended-period simulations (EPSs) were conducted for each section to understand its steady-state operation during normal operation. The
pressure transient models were validated using field pressure data, which were measured using high-speed pressure-monitoring equipment installed at selected locations in both network sections. A methodology is proposed to integrate the results of these simulations in a water utility asset management database to improve pipe failure prediction.
