To provide a cooling water producing facility capable of preventing cooling capacity from lowering even when a flow rate of cooling water in a cooling tower is low.
Cooling water producing facility 10 includes two units of cooling towers 12 and 14, a cooling water pump 18, a load section 20, a piping system 22 that distributes cooling water into the cooling towers 12 and 14 to pass water therethrough in parallel, and a piping system 24 that passes cooling water through cooling towers 12 and 14 in series. A cooling water pump 26 is provided with the piping system 24. Operation of cooling water pumps 18 and 26 is halted when the flow rate of the cooling water is low. Series operation and parallel operation of the cooling towers 12 and 14 are launched by start and stop of the cooling water pumps 18 and 26. In the cooling water producing facility 10, the cooling towers 12 and 14 adopts a piping system to be a parallel connection at the time of a maximum load, and when the flow rate of the cooling water is low, the cooling water pump 26 performs ON/OFF and switching valves 28A and 28B are opened and closed so as to be a series connection.
