TEVA-SPOT software was released in 2008 as a freeware dedicated to water and sewer utilities. It enables modelling of various of measurement points, and built-in tools to conduct more in-depth examinations. This paper presents selected possibilities this program grants in the context of emergencies, terrorist attacks or if it is used as an early warning system. It had gone through a hands-on examination and its results-advantages, difficulties and limitations have as well been described here.

Modeling of water network distribution systems must base on either actual data from water monitoring systems or the GIS data. The methods applied during design works on measuring points' localization and quantity ought to respect a number of criteria. One of them is an ability to apply monitoring as a critical element of the early watch system. This article discusses importance and measuring points' localization strategy using the TEVA-SPOT as the dedicated software. Further, it presents the challenges and limitations of this one and similar programs from the perspective of their application in large agglomerations. It emphasizes various incidents and describes their integration with the modeling software.

Deployment of IT solutions in water utilities in Poland concerns nowadays lots beyond GIS implementation projects [1]. The scope of modern IT platforms is truly advanced software for complete management of water treatment processes and involved objects, including ranges of various types of equipment. There are multiply factors that disrupt required volumes of supplied water. They are normally classified as natural, accidental and intentional. This paper addresses potential residing in already deployed IT solutions of water utilities in and also in new ones being now developed. Primarily- from the perspective of intentional, terrorist threats. This document depicts operating procedures that are called in case of spotted contamination in a water supply (damage of key elements of the network infrastructure) or in case of an introduction factors. This paper also discusses relevant IT tools with access provided to network operators or water plant owners that are extremely useful in accurate pinpointing the treat and in following relevant operating procedures and related actions.

This report presents a selection of exploitation problems which can be effectively solved by water network modellers. It includes a list of worldwide-available software dedicated to modeling water distribution systems. This type of software can serve as the key tool supporting management and water pipe networks' control. Based on a few samples of real-life problems this report points out recent functionalities and methods. Moreover, there are presented some new trends and main problems in water network modeling.
