What is Wellpoint Dewatering?
Wellpoint dewatering involves installing a closely spaced line of small-diameter wells alongside an excavation—or a ring of wells around an excavation. Each well, known as a "wellpoint," is designed to be low-cost yet robust, effectively lowering the groundwater table to ensure safe, dry working conditions for foundation work, pipeline installation, and underground construction.
Primary Application
Construction site wellpoint dewatering
Groundwater control for excavations
Foundation stabilization
Tunnel and pipeline dewatering
