That drawing isn't set in stone. It can be changed to fit any scenario. That is just a rough first draft.

You can put soil on top of a drain but, it (especially clay) will seriously impair the drainage.

I think you are thinking of this kind of pipe. - picture on the left.

This is the kind of pipe i am talking about. - picture on the right.
The perforations go all the way around the pipe on that. But if you were using rigid perforated pipe then yes you would put the hole's facing down.
Can anyone explain to me the difference. I have seen some videos online with a perforated pipe all around, and have seen some with holes only on one side like this

Whats the difference? Pros? Cons?
