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:
“I come to this land to ride my horse,
to try my own guitar, to copy out
their two separate names like sunflowers, to conjure
up my daily bread, to endure,
somehow to endure.”
—Anne Sexton (1928–1974)
“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)
