Dewatering pumps are centrifugal pumps installed in a building that is situated below the groundwater level, to reduce the water level and then maintain it at this level.
Water pumps are designed to move water from one location to another, while dewatering pumps are designed to remove water from an area where it is not wanted, such as from construction sites, mines, or flooded areas.
In the construction and mining industries, dewatering pumps can be used for the removal of groundwater, or surface water, to lower the water table.
