To provide a water feed system configured to solve problems by enabling a water feed system side to have a pressure target value, an initial inverter frequency (target flow rate) and a function for designating the number of necessary pumps.
A water feed system comprises: a setting means for setting parameters such as a flow rate target value necessary for a load of each water feed implement, a pressure target value and rotation speeds corresponding to these values; a first communication means for transmitting an operation status of the water feed implement; and a second communication means arranged at a control device. When the second communication means receives signals from the first communication means, the control device acquires a maximum flow rate of a load obtained by totalizing the flow rate target values of the respective water feed devices corresponding to the received signals, acquires the number of pumps for performing constant-speed control from the maximum flow rate of the load and a maximum water feed amount, and a remaining water amount, acquires an initial speed of the pump corresponding to the remaining water amount, constant-speed controls the prescribed number of the pumps, and constant-speed controls the other pumps at the initial speed.
