Full Description

This paper provides a case study on how several control systems were implemented using a business model, how East Bay Municipal Utility District (EBMUD) plans to transition to a new Supervisory Control and Data Acquisition (SCADA) system and how the District is using the lessons learned from this process to apply it to future information system projects. Specifically, EBMUD's control systems include: OP/NET, a SCADA system which monitors and controls two hydroelectric power plants, 91 miles of aqueducts, seven raw water lakes, 129 pumping plants, 170 treated water reservoirs, 25 rate control valves and 10 regulators; AIMAX, a man machine interface which runs on a PC platform which provides an operator interface for monitoring and controlling filter backwashes and chemical feeds; and, OSCI, a process data historian which has archived historical data with near real time resolution since 1994.
