Lowering of the ground water is the simple, traditional and cheapest way of ground water control in excavations, modifying the subsurface flow pattern.

There are different ways of lowering the ground water table .   We currently use the following techniques:

1- Surface dewatering

2- Well Point System

3- Deep Wells

Groundwater lowering must meet the following criteria:

- No wash out of fines - Excavation must proceed in a dry condition - The bottom and sides of the excavation must be stable.
