History
During the first UN decade on water boreholes, hand-dug wells and tubewells were constructed and water pumps were provided to developing countries by various NGOs. Unfortunately this top down approach led to the installation of pumps, notable the India Mark II, that were difficult to maintain. VLOM pumps were designed to allow remote villages to maintain pumps themselves as part of a larger strategy to reduce the dependency of villages on government and donor agencies and provide more sustainable access to drinking water.

Famous quotes containing the word history:
“There are two great unknown forces to-day, electricity and woman, but men can reckon much better on electricity than they can on woman.”
—Josephine K. Henry, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 15, by Susan B. Anthony and Ida Husted Harper (1902)
“The history of work has been, in part, the history of the worker’s body. Production depended on what the body could accomplish with strength and skill. Techniques that improve output have been driven by a general desire to decrease the pain of labor as well as by employers’ intentions to escape dependency upon that knowledge which only the sentient laboring body could provide.”
—Shoshana Zuboff (b. 1951)
“The History of the world is not the theatre of happiness. Periods of happiness are blank pages in it, for they are periods of harmony—periods when the antithesis is in abeyance.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
