Abstract
Aging pipes in residential water distribution networks may affect the quality and amount of treated water delivered to residents. So, a calibrated water distribution model is useful for monitoring and analyzing the behavior of a real water distribution network. However, the literature lacks a complete performance indicator and an integrated technique for assessing the efficiency of model performance. This work created a methodology for a model calibration that takes into account two uncertainty parameters, namely pipes Hazen-William roughness coefficient and expected nodal demands. The purpose of this paper is to simulate and calibrate a large and poorly documented water distribution network (WDN) in Suez City that exhibits pressure deficit problems. Field measurements are carried out to contribute to the development of the initial WDN model. A trial-and-error approach was then utilized to develop consecutive improvements for the desired WDN's model fit utilizing Darwin Calibrator, a tool in Bentley Water GEMS V10i Update 3 software. This paper discusses the process that was taken from the initial model to the final calibrated model and the steps taken to improve pressure issues and findings suggest that integrating GIS and WaterGEMS creates a network management system that can identify issues, address emergencies, and assess network performance.
