Construction Dewatering
The purpose of construction dewatering is to control the surface and subsurface hydrologic environment in such a way as to permit the structure to be constructed “in the dry.”
Dewatering means “the separation of water from the soil,” or perhaps “taking the water out of the particular construction problem completely.”
This leads to concepts like pre-drainage of soil, control of ground water, and even the improvement of physical properties of soil.
