This paper describes the system that ties together the State of California's bulk water conveyance system, which is the largest in the world. The system features more than 700 miles of canals and pipe, 23 pumping plans, 130 hydroelectric units, and more than 90 flow control structures. The primary components of the control system include: the operations center, development and decision support system, catastrophic backup, 4 area control centers located along the aqueduct; 8 major plant control systems, 10 minor plant control systems, 129 RTUs at flow control structures and other points, and two system communications hubs. The paper describes design principles, testing, some discussion of the reasons to use bridges rather than routers, the features of the bridges chosen, and alarms.
