High pore pressures occur in soils composed of fine silts or clay's. Since these soils have a very low permeability, vacuumassisted dewatering scheme, such as ejector wells, or vacuumsealed deep wells may serve to draw water into a well for abstraction. Safety on the job; Wet or muddy ground produces unsafe working conditions for workers.
The purpose of a dewatering system is to control groundwater levels and to reduce pore water pressure in the ground. OGI is able to analyse available geological data and the geometry of a construction site excavation to develop a conceptual model.
Abstract: Dewateringinduced ground settlement is an important issue, and there a cumulative effect in stratified soil settlement. Detailed research of the stratified soil settlement devotes to a better evaluation of ground settlement.
Dewatering / d iː ˈ w ɔː t ər ɪ ŋ / is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solidliquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.

In the case of the consolidation settlement of a confined sand aquifer overlain by a clay layer due to single well dewatering, a simplified analytical solution is provided by Niu et al. . However, most of the existing studies focus on the calculation of ground settlement, and few are involved in the settlement characteristics of a stratum.
