sunken island drainage

Hey all -

Was wondering how the sunken island/lounge drainage works in scenarios like this:

Does anyone happen to know?

Probably through a drain run out past the infinity edge, I would guess.

You'd definitely want a floor pit with plenty of capacity in there, but it could drain to any point as long as the lowest point is lower than the floor level in the set-down.
