Our daily need about water is absolutely essential. Therefore we need some equipments which can support to supply the water accordance with our needed. For example%2C to supply the water in hotel%2C the greater the amount of using the water then we need performance of water pump more and more to move the water from low surface to the higher. However%2C often using of pump is not comparable with our needed and the pump is often operated continually so there are some electrical power and some water that neglected. In this paper%2C the using of water pump will be controlled by speed drive inverter. Motor pump can be arranged so output rate flow of the pump that become accordance with load of using of the water. The controlling of motor is done by inverter by change the frequency%2C but automation is controlled by PLC by using limit switch as sensor of elevated at reservoir and as varian frequency input on inverter%2C also we use pressure switch as automation on-off pump with pressure method. On testing of performance of the equipments%2C obviously it shows total of efficiency of system is not very big. For arranging 35-50 Hz%2C total efficiency reaches only 14 %25.
