Gravity drainage (wastewater design options)

In the Calculation options area under Calculation, media-specific settings for the individual section types, global settings for the filling level and backflow level as well as for pressure drainage are defined.

Section types

Switch between the individual tabs to define the settings for the individual section types for each medium.
Activate the Minimum/maximum requirements in accordance with DIN 1986-100 checkbox to specify the definitions of the respective tab in accordance with DIN 1986-100.

Backflow level

Enter the height of the backwater level in metres in the Height of backwater level input field.

Note:
The entered height of the backwater level is the default value for all backwater levels within the drawing.

Filling level

Enter the minimum fill level in % in the Minimum fill level input field.

Note:
The minimum fill level entered applies to all media and section types.
