The wells at Harappan sites show a developed technology. Those at Allahdino (Baluchistan) with their small diameter, location at the top of the site, and the divided drains with movable sluice block suggest well water irrigation (Possehl, 1979, p. 210). Some of the water lifting devices associated with the Harappan wells can be determined. Sign of friction by the ropes on the sides imply drawing of water by a rope with pots attached to it. It has been suggested that the water-lifting device of shaduf was in use. The picture of a man using shaduf at a well is embedded on a piece of lime at Mohenjodaro. The ring-stones recovered from Mohenjodaro and Lothal are explained as counter-weights for the arm of a shaduf. Mackay suggests that the scored pottery from Mohenjodaro was attached to a wheel, which was managed by an endless rope, for drawing water for irrigation (Marshall 1931, I, p.318)54.
