Chapter 10PLANT MONITORING ANDCONTROL SYSTEMS: MAKING THECASE AND MANAGING THEIMPLEMENTATIONM F Williams (Severn Trent Water, UK), D L Gartside (Kennedy &Donkin Systems Control, UK)ABSTRACT:Severn Trent Water has in excess of 5000 operational siteswhich require the monitoring and control of mechanical andelectrical plant.In late 1988 a study was made of the plant monitoring andcontrol issues which resulted in a business case for a telemetrysystem to provide remote monitoring and control of 3500 sites.Design and implementation of the system commenced in early1989 with a target for completion by the end of 1992.The Paper describes the business case methodology and theproject management techniques used to define, design andimplement the system.The Business Case preparation included a review ofappropriate design solutions, cost estimates, interfacing ofexisting telemetry and ICA systems, implementation andprogramming issues.This involved use of sample engineering audits of operationalsites to determine site functionality, existing investment inICA and Communications. Overall scheme requirements beingextrapolated using databases and financial modellingtechniques.In the design of the scheme, users requirements were satisfiedby producing design intent documents for Telemetry,Instrumentation, Communication and interfaces to ICASchemes. Presentations and demonstrations to users were akey feature to obtaining user acceptance.© 1991 Elsevier Science Publishers Ltd, EnglandWater Treatment—Proceedings of the 1 st International Conference, pp. 89–10489
