Land Drains
The purpose of a land drain is to allow water in wet or swampy ground to rapidly drain away or to relieve hydrostatic pressure. They are subterranean linear structures which are laid to a fall which should be as steep as practicable. They are used in agriculture and in building construction sites. Modern land drains take the form of a perforated or discontinuous (i.e. open-jointed) pipe. Typically, the land drains conduct the surplus water to an open ditch or natural water source.

Famous quotes containing the words land and/or drains:
“Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.”
—Germaine Greer (b. 1939)
“I change, and so do women too;
But I reflect—which women seldom do.
Tobacco is a filthy weed,
That from the devil doth proceed;
That drains your purse, that burns your clothes,
That makes a chimney of your nose.”
—Anonymous. “Written on a Looking Glass,” from Geoffrey Grigson’s Faber Book of Epigrams and Epitaphs, Faber & Faber (1977)
