Implementing a pipeline strategic renovation plan using a MIS (GIS) approach

it appears that Water Boards/Utilities worldwide focus in their rationale to a selection criteria model on only one or a few parameters to base their decision of whether or not to renovate pipes. Rand Water recognised that it is evident that with state-of-the-art, integrated technology, more accessible and up-to-date information data bases, more complex and innovative selection criteria models will have to he implemented. This is necessary in order to cope with realistic requirements to supply our customers trouble-free in the long term. Rand Water considered two models with the preparation of a 5-year Strategic Renovation Plan (SRP), namely: the multiple queries model and the selection criteria model. The application of these two models to implement the SRP will be discussed.
