How do you design a drainage?

DESIGN OF SUB-SURFACE DRAINAGE SYSTEMS Sub-surface drainage is the removal of excess groundwater below the soil surface. It aims at increasing the rate at which water will drain from the soil, and so lowering the water table, thus increasing the depth of drier soil above the water table.
