drainage pipe for downspouts

I want to run 2 downspouts into a 4' solid pipe and put underground. However, the way the lay of land is if i put very far underground by the time it will exit in the back swale the pipe will be half as deep as the swale is. Say there is a lot of rain and the swale is full, my pipe will be about 10" under water. What will happen to the water thats trying to drain out off the roof?I dont mean to confuse you.

I would think that the pressure of the water coming from the gutter would allow the gutter to drain. Yes there will be some water backed up in the drain pipe until the water in the swale recedes, but it shouldn't be a problem.

Thank you for your reply. We are thinking about the same here so I feel ok with it.

Now comes the hard part of trenching and laying the pipe.

Have a nice summer!
