Sump

Reservoir or pit in the basement of a house into which water can drain, especially during flooding. A sump pump is used to pump collected water out of this reservoir to the sewer pipes.

Sump

 

in mining, an underground working for the collection of surface and subterranean water so that it may be pumped away. The size of the sump is based on the amount of inflow during a period of ten to 12 hours with all drainage pumps shut down. Under emergency flow conditions in a mine, use is made of the additional capacity represented by the workings lying adjacent to the sump and below the pump chamber. The sump is divided by a cofferdam into two sections; when one is in operation, the other is drained.

As places where water accumulates during drainage, sumps are used in mines, subway tunnels, quarries, and elsewhere.
