A carbonate spring producing system includes a gas-liquid separator ( 6 ) which is connected on the downstream side of a carbonic acid gas dissolver ( 4 ). A carbonic acid gas supply means ( 10 ) and hot water supply means are connected to the carbonic acid gas dissolver ( 4 ). A liquid lead-out pipe ( 5 ) is connected to the gas-liquid separator. Preferably an un-dissolved carbonic acid gas lead-out pipe ( 23 ) is connected on the upstream sides of the gas-liquid separator ( 6 ) and the carbonic acid gas dissolver ( 4 ). The un-dissolved carbonic acid gas lead-out pipe ( 23 ) includes a control valve ( 25 ), a compressor ( 27 ), and a liquid level detection means ( 22 ). The control valve ( 25 ) controls a flow rate of un-dissolved carbonic acid gas from the gas-liquid separator. The liquid level detection means ( 22 ) measures a liquid level of the gas-liquid separator. Control means ( 28 ) controls the flow rate of the supplied carbonic acid gas and the flow rate of the supplied un-dissolved carbonic acid gas based on the gas-liquid separator liquid level detected by the detection means ( 22 ). An amount of un-dissolved carbonic acid gas in the gas-liquid separator is always monitored, so that the un-dissolved carbonic acid gas in the hot water can securely be separated and removed by the gas-liquid separator, and the separated and removed un-dissolved carbonic acid gas can be redissolved.
