Land Drainage
When low lying areas of land are drained, the general method is to dig drainage ditches. However, if the area is below sea level then it is necessary to pump the water upwards into water channels that finally drain into the sea.
The Victorians understood this concept, and in the United Kingdom they built pumping stations with water pumps, powered by steam engines to accomplish this task. In Lincolnshire, large areas of wetland at sea level, called The Fens, were turned into rich arable farmland by this method. The land is full of nutrients because of the accumulation of sedimentary mud that created the land initially.
Elsewhere, pumping stations are used to remove water that has found its way into low-lying areas as a result of leakage or flooding (in New Orleans, for example).

Famous quotes containing the word land:
“America does not concern itself now with Impressionism. We own no involved philosophy. The psyche of the land is to be found in its movement. It is to be felt as a dramatic force of energy and vitality. We move; we do not stand still. We have not yet arrived at the stock-taking stage.”
—Martha Graham (1894–1991)
