<P>PROBLEM TO BE SOLVED: To provide a method for verifying water distribution controllability and a water distribution control method for resuming operation of a pump without causing a non-water feeding state of a supply system and feeding water into a water distribution pipe passage network smoothly. Ž<P>SOLUTION: When parameters used and required for simulation of a water distribution pipe passage network model are set and pressure and flow rate of water to be distributed in the water distribution pipe passage network model are inferred by using the set parameters and a pipe passage network analyzing means, one injection point for water to be distributed among a plurality of injection points for water to be distributed is selected, and operation of the pump connected with the selected injection point is resumed. When rotational speed of the pump reaches the predetermined prescribed rotational speed and a discharge valve at the selected injection point is opened to feed water into the water distribution pipe passage network, discharge pressure at the other injection point for water to be distributed is reduced, and typical pressure at a terminal of the water distribution pipe passage network is reduced. When it is determined that flow rate of water from the selected injection point for water to be distributed exceeds the minimum flow rate, water distribution is verified by switching from flow rate control to pressure control.
