PURPOSE: A multiple water feeding system for feeding pure water into a boiler is provided to stably feed water into the boiler by forming multiple pure water feeding lines between a pure water tank and a supplement water tank. CONSTITUTION: A multiple water feeding system includes a pure water feeding head section(30), pure water tank level detectors(10a,10b,10c,10d), a pressure detector(41), water level control valves(31,32,33,34), and a pressure control valve(42). The pure water feeding head section(30) is installed at an outlet port of each pure pump(1a-1h) and a pure water feeding line(43) is connected to the pure water feeding head section(30). The pure water tank level detectors(10a,10b,10c,10d) are installed in pure tanks(2a,2b,2c,2d), respectively. The pressure detector(41) is provided in the pure water feeding head section(30). Opening/closing of the water level control valves(31,32,33,34) are controlled by supplement water level detectors(4a,4b,4c,4d).
