A water balance according to IWA standards.
In order to generate the water balance, the user has to select the time period for which it should be generated. This can be either a month or an arbitrary time period.
Most of the data is generated by aggregating data of the individual meter types for each ROU. However, the following figures are calculated from other figures in the table:
System Input: The sum of "Internal Production", "Import from Transmission", "Import from East Transmission", "Import from WAJ", "Import from Other Operational Area" and "Import from Private Source".
Billed Authorised Consumption: The sum of "Billed Quantity", "Reductions", "Export to Transmission", "Export to East Transmission", "Export to Outside", "Export to Other Operational Area", "Irrigation" and "Tanker Filling".
Unbilled Authorised Consumption: The sum of "Animal Feeding" and "Other Unbilled Authorised Consumption".
Authorised Consumption: The sum of "Billed Authorised Consumption" and "Unbilled Authorised Consumption".
Water Losses: The difference between "System Input" and "Authorised Consumption".
Non-Revenue Water: The difference between "System Input" and "Billed Authorised Consumption".
