Command center for wastewater resources

After the module has been selected, a form "selection criteria" will open. This form looks similar for all modules, and functions as a "command center" to initiate the following operations:

• Spatial selection of demand centers (uses a separate form)
  
  Note:  Inverse Selection  will only be applicable after the demand centers of the first data selection have been processed.
• Entry of reference year (absolutely necessary, if this field is empty you can not proceed entering demand-related data)
• Reduction of the results from spatial selection with the following query criteria:
  
  individual ID of WWT Plant,
  
  Owner ID of WWTP (according to the WWPT_OWNERSHIP codes) - use the pull-down menu for selection,
  
  Type of WWTP (according to the technical classification defined in WWTP_TYPE) - use the pull-down menu for selection,
  
  This helps to distinguish the different WWTPs, as they may have a different development.
• Alternatively, you can load the demand centers and the reference year from a previous session .
• Export data from the reference year to Excel .
• Export data from the reference year to STP .

The screenshot below shows the form after spatial selection and entry of a reference year. Like most other forms, also this form possesses a number of controls. Move with the cursor over the image. If the cursor changes from arrow to a hand, you can click to find detailed explanation about the controls.
