PERFORMANCE EVALUATION OF GROUND WATER PUMPING - SYSTEM

Abstract

The present thesis work is carried out on the tube wells of Roorkee, where the discharge and the pipe lengths and current consumption and the power of the pumps of 48 tube wells are collected for which the department of tube wells, Roorkee was approached which provided the transport facilities for the work carried. Proper selection of a submersible pumps is essential for good life of tube well and its appropriate utilization. If a pump of higher head and discharge is used than required then higher initial cost, operation cost will incurred and tube well life will also be reduced. Similarly if a pump of under head or discharge is used tube well capacity will be utilized. Hence a tube well must be tested as per standard practices for a safe capacity of discharge at safe drawdown of water. Irrigation is of paramount importance in development of agriculture. India has a unique agro-climatic permitting the cultivation of variety of crops adapted to tropical, subtropical, temperate, semi and and and environments. Thus, Indian society is mainly agrarian with about 75% of the people depending on agriculture. In India about 68% of total sown area of the country is drought prone. Irrigation development has a major factor in increasing agricultural production. So therefore all the pumps data is analyzed to pick the pumps which will not work properly throughout the year that is the pumps which fail in summer season where the drawdown is not considered are found out and these pumps should be replaced so that there is continuous supply of water throughout the year for the farmer...
