The Woodingdean Water Well is the deepest hand-dug well in the world, at 390 metres (1,280 ft) deep. It was dug to provide water for a workhouse. [1] [2] Work on the well started in 1858, and was finished four years later, on 16 March 1862.
Interior of a brick-lined well in Utrecht, Netherlands. A brick-lined well is a hand-dug water well whose walls are lined with bricks, sometimes called "Dutch bricks" if they are trapezoidal or made on site. The technique is ancient, but is still appropriate in developing countries where labor costs are low and material costs are high.
Although it is billed as the world's largest hand-dug well, at 109 feet (33 m) deep and 32 feet (9.8 m) in diameter, [6] the Well of Joseph in the Cairo Citadel at 280 feet (85 m) deep and the Pozzo di San Patrizio (St. Patrick's Well) built in 1527 in Orvieto, Italy, at 61 metres (200 ft) deep by 13 metres (43 ft) wide [7] are both actually ...
The Woodingdean Water Well, hand-dug between 1858 and 1862, is the deepest hand-dug well at 392 metres (1,285 ft). [15] The Big Well in Greensburg, Kansas, is billed as the world's largest hand-dug well, at 109 feet (33 m) deep and 32 feet (9.8
The earliest wells were water wells, shallow pits dug by hand in regions where the water table approached the surface, usually with masonry or wooden walls lining the interior to prevent collapse. Modern drilling techniques utilize long drill shafts, producing holes much narrower and deeper than could be produced by digging.
During the Neolithic era, humans dug the first permanent water wells, from where vessels could be filled and carried by hand. Wells dug around 8500 BC have been found on Cyprus, [2] and 6500 BC in the Jezreel Valley. [3] The size of human settlements was largely dependent on the amount of water available nearby.
A tankhouse (also spelled tank house or tank-house) is a water tower enclosed by siding. Tankhouses were part of a self-contained domestic water system supplying the house and garden, developed before the advent of electricity and municipal water mains. The system consisted of a windmill, a hand-dug well and the tankhouse.
Most hand pumps are either piston pumps or plunger pumps, and are positive displacement. [1] Hand pumps are commonly used in developing countries for both community supply and self-supply of water and can be installed on boreholes or hand-dug wells.
