The information systems that water supply companies use for management purposes are equipped with a variety of increasingly sophisticated tools such as geographic information systems (GIS), supervisory control and data acquisition (SCADA), work flow management and mathematical models. These tools must be integrated if they are to be truly efficient. While a GIS system can be used for infrastructure management purposes, all of the information available on existing maps must be checked and verified. However, since distribution systems are dynamic and change as maintainance and repairs are conducted, it is not always possible to guarantee that the physical infrastructure of the network has not undergone changes. A telemetry system (SCADA) can be used to provide real-time information about system dynamics such as water flow, pumping station operations and valve control. Finally, a work flow management system can be used to track maintenance and repair work. This paper describes the successful integration of these three tools by the Canal de Isabel II in Madrid, Spain. The Canal de Isabel II has established a GIS-based system for controlling its distribution network. The system incorporates all the data received from the SCADA and work flow management systems, making it available to contingency management and customer information services and using it in the mathematical models that analyze the network.
