- SORA projetc: Monitoring dashboard of water distribution network

The city did not have an overview of the "behavior" of the drinking water system. Only the operation screen pages were available. This software is used in a first step to present the entire drinking water network of the City of Quebec grouped into distribution network, pressure levels and consumer sectors. It displays in real time the pressures of the various structures on the periphery as well as the consumption of the sectors according to the supply or the withdrawal in each sector, while taking into account the reservoirs. Different alarms are also used for decision making. The second component is used for water balance calculations by providing a validation tool. Access to city tools such as the interactive map allows to visualize a wealth of corporate information such as the location of pipes, the infrastructure management system giving all the information of the works and a satellite image to identify the different structures.

- The contribution of integrating interoperable data, for the orientation of urban developments

The evolution of databases and the generation of information of all types via a multitude of monitoring media, sensors, scanned imagery, etc., is a wealth of information commonly called "Big Data". Such a proliferation of technical, sociological or geographical data opens the door to increasingly "expert" analysis systems based on the interoperability of data. In the context of the European reports an integrating tool for heterogeneous, geo-localized data from all European Union countries has been developed to automatically make data sets more reliable, to make the different sources interoperable, to harvest open access information and enable integrated analysis of results. The cross-referencing of multiple data thus allows for correlated analyzes, making it possible to represent and identify the influencing factors on the quality of the discharges, or the receiving environment, on a European scale. This type of tool can be generalized on the orientation and management of infrastructure.

- Description of the work methods by sectorisation of the aqueduct network

The City of Gatineau has conducted a survey of its cast-iron aqueduct system by listening to the gates and fountain terminals. The installation of the Ortomats and the taking of data of these are carried out by day while the network is auscultated at night by the Ortomats. Leaks are precisely located in the alert polling areas and the network is listened to on the points of contact near the alert. Subsequently, the location takes place by the acoustic correlator and is confirmed by listening on the ground.
