surface water drainage

i am building an extension at the rear of the property, and the original house never had rear surface water drainage installed. the nearet gully is at the front of the property.

i cant use a soakaway due to the water table being to high.

how can i avoid having to dig up metres of concrete to get to the front of the property so i can drain away the surface water.

i have checked also, that i cant put it into the foul drainage

You should be able to but may have to pay for the privilege.
