This is the most economical technique and is also possible of becoming executed with unskilled labour and quite simple devices.

Wellpoint consists of a perforated pipe, one hundred twenty cm extended and four cm in diameter by using a valve to control circulation in addition to a screen to stop entry of mud and so on. These wellpoints are mounted together the periphery of your excavation within the necessary depth and spaced at about one m. The exact spacing may be selected The idea of the type of soil. Wellpoints are surrounded by sand gravel filter and have riser pipes of five to seven.five cm diameter. These pipes are connected to a header pipe which can be connected to the substantial ability suction pump. The groundwater is drawn out with the pumping motion and it is discharged faraway from the positioning of excavation. Fig: Reducing H2o Table by Wellpoint
