Removing water from an area using a pump or drain is known as ________.

• A. Dehydration
• B. Drainage
• C. Dewatering
• D. Water withdrawal

Answer: (C)

Dewatering is the process of removing water from an area using a pump or drain. In earthmoving, keeping the excavation dry is essential to prevent mud, protect the stability of the soil, and allow equipment to operate safely. Dewatering lowers the groundwater level or drains surface water so the work zone remains dry, using methods like sump pumps, wellpoints, or drainage networks. Dehydration would refer to removing water from a material or a person, not from a construction site. Drainage focuses on surface water management to avoid standing water but doesn’t necessarily remove water from within the ground to create a dry working area. Water withdrawal is a general term for removing water from a source, not specifically the process of drying an excavation. So the best fit is dewatering.
