Dewatering is the temporary or permanent removal or lowering of groundwater from an excavation or site to allow construction below the water table in dry, stable conditions. Techniques include well points, deep wells and sump pumping; in data-center works it enables safe excavation for foundations and basements and controls water ingress and ground instability during construction.
