French drains are used as a form of land drainage and are named after Henry French, the 19th-century American farmer who developed and popularised them.

French drains are one of many drainage systems used to prevent water logging and an excess of surface water. They consist of a trench dug, at a gradient, into the ground, lined with membrane, filled with aggregate and, usually these days, a perforated drainage pipe.
