How does a dewatering system work? What is dewatering, when is it use and methods? Methods of Dewatering Excavations at Construction Site.
The eductor well method is a dewatering process used to control pore water pressures in materials with low permeability characteristics, such as fissured clays or silts. This method uses the venturi principle, where high pressure water is circulated through eductors in the base of each well to create a vacuum that helps promote drainage.
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. Belt press issues, belt filter press and centrifuge are some of the examples of dewatering. It is also important to choose the best location for discharge , even when you might be far away from water bodies or catch basins. Purpose of Dewatering Sump pumping.
Well point systems with suction pumps. Shallow wells with pumps. This frequently involves the use of submersible dewatering pumps, centrifugal (trash) pumps, eductors, dewatering by electro osmosis, or application of vacuum to well points.
