<P> A water well is an excavation or structure created in the ground by digging , driving , boring , or drilling to access groundwater in underground aquifers . The well water is drawn by a pump , or using containers , such as buckets , that are raised mechanically or by hand . Wells were first constructed at least eight thousand years ago and historically vary in construction from a simple scoop in the sediment of a dry watercourse to the stepwells of India , the qanats of Iran , and the shadoofs and sakiehs of India . Placing a lining in the well shaft helps create stability and linings of wood or wickerwork date back at least as far as the Iron Age . </P>
