Quick Scenario Builder - Wastewater Resources
This "Quick Scenario Builder" gives you a complete overview of total
resources of treated wastewater as well as a single user interface to
quickly build scenarios 2 and 3 out of data previously entered under
Only the coverage rate as principal parameter can be changed.
However, in most cases it will be sufficient to recalculate
WW-resources due to changed demands.
When the form opens, it shows data for the first balancing year.
A different balancing year is selected by year-selector on top of the form ,
The data table in the form shows the spatial selection (the individual treatment plant) and the total annual demand as saved in the STP file STP_WWTP as monthly volumes of each demand center.
The coverage rate shown on the right side is not a data table but rather a list box permitting the selection of records for updating.
Data manipulation is possible in 3 different ways:
- Fill data: For scenario 2 or 3 selected by the fill-button
located under the column, data from scenario one are copied. This does
not only include STP data, but log-table data as well. Afterwards, the
display of demand volumes and irrigated areas is refreshed.
- Empty data: For scenario 2 or 3 selected by the delete-button
located under the column, STP data are set to zero and log data are
removed. Afterwards, the display of demand volumes and irrigated areas
- Recalculate data:
The 3rd option is more complex. It makes only sense after the scenario
has already been populated with data. You have to select one or more
records in the list box (showing the coverage rate) and have to enter a
new value, with which will replace the previous values. Select the
option if only the year currently shown should be updated (this is the
default), the year shown and the following years or even all years.
After records have been selected and the multiplication factor has been
set to a value <1, the hammer-button becomes enabled and can be
This will recalculate coverage rate and total resources of treated
wastewater in a simple way, by just replacing the coverage rate stored
in the log tables by the new value and than recalculating the STP-data.
