Realistic forecasts are based on a sound understanding of the present situation. In order to obtain that understanding, the available monitoring data need to be analysed. As such an analysis is often most conveniently done under MS-Excel, the preprocessing module permits the export to Excel of figures relevant for the calculation of wastewater resources.
The original concept of linking resources (production wells) and supply zones could not be maintained, due to data problems and frequent changes to the physical distribution system. The available data do not permit to compare "input" and "use" data, only the distributed water (according to billing data) can be shown.
All flow data are monthly totals in m3. The examples shows also apparent data gaps (zero volumes billed).
