Position Paper for Beyond SCADA: Networked Embedded Control for Cyber Physical Systems workshop

SCADA and GIS for drinking water distribution system monitoring and response: critical gaps Shannon L. Isovitsch1 and Jeanne M. VanBriesen2 SCADA is frequently used to manage and control drinking water treatment systems. In this application, SCADA systems perform remote monitoring and operations control along with data management and storage. SCADA systems often serve the joint purposes of operational information and regulatory compliance data management, The most important challenge in the advancement of SCADA systems in the drinking water industry is the need for monitoring and control ...view middle of the document...

3 Expanding SCADA systems to retrieve, store, and control the water quality throughout the distribution system is needed. Integration of real-time data collection with drinking water distribution models is necessary to enable rapid detection, evaluation, and response to intentional and accidental intrusions into the system. Distribution system models contain more pipes and nodes than the SCADA system has sensors; thus model prediction can be useful in interpolating SCADA observations between monitoring points as well as to extrapolate SCADA observation in the future.2 One of the primary uses of a water distribution model is to predict the effect that an emergency will have on the system and quickly develop appropriate corrective action. The overall goal of SCADA advancement in the drinking water industry over the next 5 to 10 years should be incorporation of the distribution system into current SCADA plant-centric systems, and addition of real-time water quality sensing information to the water quantity information now archived. These goals will only be reachable through integration of SCADA,


distribution system water quality models, and GIS. The security of the nation’s water supply requires these advances. ______________________________ Shannon Isovitsch is a graduate student in the Department of Civil and Environmental Engineering at Carnegie Mellon University.
