Industrial control systems are computer controlled systems that monitor and control industrial processes that exist in the physical world. New Brighton's sanitary sewer SCADA system monitors the following: (1) sewer level within the lift stations, (2) if the pumps are functioning, (3) high level alarms, (4) telemetry failures, (5) temperature inside the lift stations, (6) power failures, and (7) allows the operator to remotely control the lift station set points. The current SCADA system was furnished by US Filter in year 2000. Major components of the system include the following: •One computer and monitor •Wonderware software and license •One Operator interface module with primary PLC control panel •One telephone autodialer •Five PLC field control panels The SCADA system currently uses dedicated telephone circuits between each lift station and the main control panel to report alarm messaging and operational information that is stored on the system computer. Condition Assessment and Recommendations • SCADA System - The computer and wonderware software are over 10-years old and are considered obsolete. The software license has lost all of its value and capacity to function on the supporting operating systems currently available (MS Windows) and the future release of Windows 8. Replacement of the computer and software is recommended in 2013. The cost for this replacement is split evenly between the five lift stations and is included on the individual lift station assessments.
