Dewatering systems

Jun 20- Dewatering systems are routinely used in the construction industry to provide temporary reductions in ground water levels for structures which . Dewatering involves controlling groundwater by pumping, to locally lower groundwater levels in the vicinity of the excavation. The simplest form of dewatering is sump pumping, where groundwater is allowed to enter the excavation where it is then collected in a sump and pumped away.

Dewatering and groundwater control systems are occasionally required as permanent dewatering systems, intended for very long term operation as a part of . Dec 20- such settlement should be investigated before a dewatering system is designed. Establishing reference hubs CHAPTER FOUR . Methods of Dewatering Following methods are used for Dewatering,.

Sump pumping; Well point systems with suction pumps; Shallow wells with pumps; Deep . Well point systems from Griffin Dewatering are the most versatile dewatering method and can pump low or high volumes of water in coarse sands and gravels. A wellpoint dewatering system consists of a series of shallow wells, known as wellpoints, which are installed at a pre-determined depth and appropriate spacing .

At depths greater than 45-50m, ejector systems can become inefficient, often. Ejectors occupy a niche in the dewatering industry, where pumping levels are too .
