This Architectural Drawing is AutoCAD 2d drawing of Plan and section of water table below CBL. Underneath the water table is the saturated zone, where water fills all spaces between sediments. The saturated zone is bounded at the bottom by impenetrable rock. A water table is a projection of lower masonry on the outside of a wall slightly above the ground. The water table may be at a depth of less than a metre or may be several metres below the ground. ... The process of seeping of water into the ground is called infiltration. The groundwater thus gets recharged by this process. At places the groundwater is stored between layers of hard rock below the water table. For more details and information download the drawing file.
