Direction of flow for water falling on top of buildings

Ellie W

Hi there,
For the rainfall overlay, I am wondering where the water is directed to flow once it falls on top of a building? By default will it flow to the neighboring cell (e.g. a garden), or is it connected to the sewage system?
If it is not connected, is there an option to adjust this so that water falling on top of buildings are directed to the sewage system?

Thanks!

Hi Ellie,

The information about the rainfall overlay is documented on these pages:
http://support.tygron.com/wiki/Surface_water_model_(Water_Overlay)
http://support.tygron.com/wiki/Sewer_model_(Water_Overlay)
http://support.tygron.com/wiki/Storage_model_(Water_Overlay)

I think these will help you to the answers you are looking for.
Basically it comes dow to this:

If there is storage, it will enter the storage

If it is sewered it will go into the sewer.

If both of these options are not available it will stay there or drain off the roof.

I hope this helps you.
