In 1988 Wessex Water decided that its 10 year old regional telemetry system was in need of major uprating and improvement to meet their changing requirements. This paper explains the philosophy adopted in making the changes and describes the actual improvements carried out. While still based on a centralised system, two important changes included the use of more sophisticated outstations and the provision of a networking facility to VDU's for use by geographically spaced operational staff.
A number of inter-linked software packages developed for the analysis, optimisation and modelling of data are described. Finally conclusions are drawn.
