drainage question

[iaink]

i have just looked at drawings extension.a single storey wrap around.the ground slopes at ths side (the front of the house is at ground level the back door has steps leading up to it.
the drawings require a rwp at the back of the proposed extension but the height of the drain is uphill uf where the bottom of the new rwp will be.how can i make rainwater flow "up" to the drain.
thanks

did the drawings not have a drainage layout attached?

sounds as though you would have to dig a soakaway.

no drainage layouts were attatched.where should the soakaway be positioned in relation to the bottom of the rwp?
