Dewatering

Dewatering means draining underground water to lower the ground water level. This is mainly executed where excavations and civil works are to be carried out in an area of high water table. For this purpose well points or tubewells are drilled at regular interval throughout the site. Pumping is carried out round the clock till such time the water table is below the working depth. The water so drained out is rechaged to the ground through a recharge well.
