AbstractOperational analysis of water supply network using geographic information system (GIS) modeling enables estimation of effectiveness of various investment variants. Water supply network in Warsaw served as a source of data for the model, while different variants of the network expansion were compared to current operating data and water demand forecasts for the period of 2018 – 2025. It was demonstrated that the ordinary kriging method allowed for generation of a picture well illustrating variability in the network pressure distribution and credibility of the estimates was enhanced with an increase in the number of control points. Also, the kriging method enables location of regions of pressure drop in the network. Thus, not only is the method suitable for pressure decreases root cause identifi cation but also for expansion and operation of water supply systems. The models presented may be applied in the initial stage of network design, substantially facilitating it and in the same time limiting the number of emergencies and ensuring improvement in the overall performance.
