ECONOMICAL SELECfION OF TUBEWELL COMPONENTS

Different alternatives for each component of a tubewell are available in the country at present. This has created a problem for the farmers to select the economical alternative for various components of the tubewcll. A study conducted to find out the economical alternate for each component of the tubewell considering the life span and replacement cost of respective component. The most economical set of components for the tubewell consists of PVC strainer, PVC suction and blind pipe, local manufactured pump, MS discharge and delivery pipe and electric motor as prime mover. The cost per hectare centimeter of the tubewell using four types of prime mover (Peter engine, Black engine, Electric motor and Tractor) was also compared. The cost per ha-cm for the electric tubewell is less than other types for the both cases (with or without electrical connection and electrical accessories) of electric tubewell.
