De-Watering

Construction dewatering, unwatering, or water control are common terms used to describe removal or draining groundwater or surface water from a riverbed, construction site, caisson or mine shaft by pumping or evaporation. On a construction site, this dewatering may be implemented before subsurface excavation for foundations, shoring, or cellar space to lower the water table. This frequently involves the use of submersible “dewatering” pumps, centrifugal (“trash”) pumps, eductors, or application of vacuum to well points.
