i need to a drainage system for dewatering system during drilling shafts where the G.T at level of 3 m from the G.L and the invert level ranging between 9-15 m from G.L, the encountered material is silty sandy with gravels mixed with some clay, modrately cemented material, dense.
the second line composed of silty clay, the shafts depth in this material ranges about 16.00 m

i need your help to solve this problem so if anyone have a good solution dont hesitate to provide me.

Looking to hearing from you.
