A sump in a basement can be built in dry well form, allowing the sump pump to cycle less frequently (handling only occasional peak demand). A French drain can resemble a horizontal dry well that is not covered. A larger open pit or artificial swale that receives stormwater and dissipates it into the ground is called an infiltration basin or ...
A sump, or siphon, is a passage in a cave that is submerged under water. [1] A sump may be static, with no inward or outward flow, or active, with continuous through-flow. Static sumps may also be connected underwater to an active stream passage.
In mining the term sump is used to describe a hole made in the floor of a level in a working, in the direction of a lower level either for the purpose of testing the trend of an ore vein, or for the purpose of ventilation. The equivalent of a sump on a boat is the bilge. In the human eye, the vitreous humour has a minor role as a metabolic sump ...

Sump pits are also placed at suitable intervals for installation of centrifugal pumps to remove the water collected in an efficient manner. [2] In fine sands and silts, there may be sloughing, erosion or quick conditions. For such type of soils the method is confined to a depth of 1 to 2 m.

An effluent sump pump, for instance, pumps waste from toilets installed below a main sewage line. In the context of waste water treatment plants, effluent that has been treated is sometimes called secondary effluent, or treated effluent.
Sump pumps are used where basement flooding may otherwise happen, and to solve dampness where the water table is near or above the foundation of a structure. Sump pumps send water away from a location to any place where it is no longer problematic, such as a municipal storm drain, a dry well, or simply an open-air site downhill from the building (sometimes called "pumping to daylight").
