The aim of this study was to create a data model for drinking water networks based on an analysis of the information sheets drawn up by the National Water Supply and Distribution Company (SONEDE) for the collection of field data. Following validation by the operator, the model was used to set up a geographical database for the drinking water network of the Amilcar pressure stage (known as stage 76). Linking the GIS model with the Epanet software enabled the development and calibration of a hydraulic model for the drinking water network in question. Analysis of this model identified areas of excess pressure where the installation of pressure-reducing valves was therefore strongly recommended.
