Design of Pumping Plants for Tubewells

The paper deals with design of pumps both for heavy-duty and medium-duty tubewell specially for minor irrigation in West Bengal. Standard design has so far been followed despite different geohydrological condition prevalent in different areas of West Bengal. Instead of designing pumps for each and every tubewell several zones are suggested to be determined depending on the influence of the local factors, viz. the state of water level, drawdown etc. etc. This is because of regular maintenance facilities and easy availability of spare parts for the machinery.
