The most widely used tool to simulate WSSs, for both scientific and technical purposes, is EPANET version 2 ( Rossman 2000), which is a C coding language program developed by the United States Environmental Protection Agency (US-EPA). Moreover, the emergence of smart technologies has dramatically increased the amount of information available for analysing WSSs, making it even more necessary to develop suitable analysis tools. The growing necessity to improve the current water supply systems (WSSs) due to water demand rising together with increasing drought event recurrences in a climate change scenario has encouraged researchers and technicians to face several issues such as designing new systems, refitting deteriorated infrastructures and optimizing management. The plugin is available via the official QGIS Python Plugins Repository and on the world-wide-web at.

In addition, an application is illustrated to underline the novelty and the practical functionality of the presented tool, such as 3D pipe lengths' automatic calculation and the supporting functionalities for the network drawing. Several editing and graphical tools available with QEPANET are introduced to model new and existing water distribution systems, to read and modify existing text-based EPANET files, to run simulations and visualize results in a geo-referenced framework. This paper presents the QEPANET plugin, which aims at merging the flexibility of QGIS and the robustness of EPANET hydraulic simulations software.

Thus, water supply systems' modelling requires adequate tools in both the digitization and the simulation phases. In the current era, the digitization of geographical data is a transverse need of several engineering sectors, including the hydraulic networks management.
