Abstract: An Automatic bore-hole control system is designed .In all life endeavors water is needed for various purposes. In the recent time, bore-hole systems are mostly the source of portable water. Hence an automatic bore-hole control system is important in order to reduce drudgery, extra labor cost on bore-hole operation, unnecessary water loss and bottle necks in production process as a result of the lag time in starting the pump for tank refill. A spring loaded pressure control system is used in this design in contrast to floats used in similar control set ups, and is proven to be more effective and reliable .When the tank is empty the pump switches on, and when full switches off automatically. The Visual Basic programming provides an easy means of calculating spring constant needed for various heights. The device can be used for any shape of tank.
