巴黎水族馆为巴黎左岸约100万居民提供饮用水和次级饮用水。要做到这一点，它必须管理两个500公里的网络。为了改善其运营，巴黎水务公司实施了一个基于面向对象数据库的地理信息系统，该系统完全描述了这两个网络。这就需要进行大量的数据采集工作。在一年的时间里，20名实地人员收集了有关这些管道的所有细节，这些管道位于巴黎的下水道廊道中。六名绘图员随后将相应的数据输入地理信息系统（GIS）。每次管道或设备维修或更新时，所有这些数据都会定期更新。饮用水网络分为六个子网络，对应于压力级。 每个子网都需要一个水力模型，以改进泄漏检测，或测试提供新服务的可行性。为此，获得了PICCOLO网络模型。GIS中开发了一个宏命令来提取所有必要的细节，而不是输入该模型的输入数据。此外，在消费者数据库和PICCOLO之间建立了直接链接，以获取用水数据和消费者概况。一个特殊的程序分析所有这些数据，并为它们提供正确的短笛结构。PICCOLO与地理信息系统和消费者数据库的这种集成，使巴黎水务公司能够实现其配电网管理目标，并在数据采集方面实现大幅节约。 该应用程序是巴黎水资源中心的原型，如今已成为里昂水资源中心多个场所使用的交钥匙产品。

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.
