Description
Parisienne des Eaux supplies drinking water and subpotable water to about one million inhabitants of the Left Bank of Paris. To do so, it must manage two 500 kilometers networks. To improve its operations, Parisienne des Eaux has implemented a Geographic Information System, based on an object oriented database, that describes completely both networks. This has necessitated a huge effort of data acquisition. During one year, 20 people in the field collected all details about the pipes, which are located in the sewer galleries of Paris. Six draftsmen then entered the corresponding data in the Geographic Information System (GIS). All these data are regularly updated every time pipes or devices are repaired or renewed. The drinking water network is split into six subnetworks corresponding to pressure stages. For each of these subnetworks was needed a hydraulic model, to improve leakage detection, or to test the feasibility of supplying new services. The PICCOLO network model was obtained for this purpose. Instead of entering the input data for this model, a macro command was developed in the GIS to extract all the necessary details. In addition, a direct link was established between the consumer database and PICCOLO to obtain water consumption data and consumer profiles. A special program analyzes all these data and gives them the right structure for PICCOLO. This integration of PICCOLO with the GIS and the consumer database has allowed Parisienne des Eaux to meet its distribution network management objectives and to realize substantial savings in data capture. Conceived as a prototype for Parisienne des Eaux, this application is today a turnkey product in use in several sites of Lyonnaise des Eaux.
