PROBLEM TO BE SOLVED: To provide a water treatment method in which the quantity of water to be taken out of an aqueous system (taken-out quantity (X) of water) is calculated using each of various conditions of the aqueous system and, after the taken-out water is sterilized, it is again returned to the aqueous system to control the number of bacteria in the aqueous system. SOLUTION: In the water treatment method, the taken-out quantity (X) of water is calculated using formula 1 : X=-100×[H×1n(2×A-10<SP>(logA+K)</SP>/A) + B]/S (wherein A is the initial number of bacteria, B is a proliferation factor, C is a forced blow amount and S is a sterilization rate) and, after the taken-out water is sterilized, it is again refurned to the aqueous system to control of the number of bacteria in the aqueous system.
