Once the amount of usage at each use point decreases and the measurement value of water level by water level meters 61A, 61B increases, the amount of water supply to pure water tanks 60A, 60B is reduced by reducing the opening degree of control valves 59A, 59B. This increases the water supply pressure of a pressure meter 58, and thus the output by a high pressure pump 52B is reduced through inverter control on the basis of the measurement value from the pressure meter 58. On the other hand, once the amount of usage at each use point increases and the measurement value of the water level of the pure water tanks 60A, 60B becomes smaller than this reference value, the amount of water supply to the pure water tanks 60A, 60B is increased by opening the opening degree of the control valves 59A, 59B. This reduces the water supply pressure of the pressure meter 58, and thus the output by the high pressure pump 52B is increased through inverter control such that the measurement value from the pressure meter 58 becomes substantially constant. Such a control method for a pure water production system allows for control of the amount of water supply of the entire system, particularly one having a plurality of tanks, according to the amount of water usage.
