Infrastructure related data obtained from the existing reports already includes a vast amount of data. This data is more than sufficient to provide a clear overall picture of the current infrastructure development in the Orange-Senqu Basin for phase 1 of this study. For detailed modelling purposes however, one would require more information and also to update some of the data, as a fair amount of the data was obtained from old reports. The level of detail required with regards to infrastructure also depends on the level of detail that is required for modelling purposes and what one intends to achieve with the modelling of the Orange-Senqu Basin water supply system.
