A well is an excavation or structure created in the ground by digging, driving, or drilling to access liquid resources, usually water. The oldest and most common kind of well is a water well, to access groundwater in underground aquifers. The well water is drawn up by a pump , or using containers, such as buckets, that are raised mechanically or by hand. Water can also be injected back into the aquifer through the well. 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 qanats of Iran, and the stepwells and sakiehs of India.

Efficient and economical use of ground and surface water, using state-of-the-art equipment and technology, is of great importance in the present day development scenario. Water Wells and Pumps is a comprehensive treatise intended to serve as a basic reference to professionals and scientists working in the areas of irrigation, drainage, water supply, agriculture, ground water development, public health engineering, and rural development in government and non-government sectors. It will also serve as a reference for students of agricultural engineering, water resources engineering, civil engineering, environmental engineering, public health engineering, and urban and rural water supply and sanitation as well as management institutes, polytechnics, land and water management institutes, and staff training colleges of banks. For the past two decades the book has enjoyed the status of an authoritative work on the subject. The present edition is revised and updated with emphasis to the subject areas of wells and pumps, including theory and applications. It lays particular emphasis to meet the specific socio-economic situations in India and other developing countries.
Depending upon the nature of the ground water formation formation amd be tapped, the water table is prone to considerable fluctuations in relation to the incidence of rainfall, c drainage wells. Hence, open wells is classified as: i Open wells in unconsolidated formations. B. Australian Business.
