To provide an energy-saved circulation type deep water intake device which divides deep water mixed with bubbles into water and air with a branch container 8 by supplying compressed air, pumps the water and feeds the air to a second head part 14 to use to pump the water from the second head part 14 and an intermediate water intake part 16, divides deep water into water and air with a branch container 24, and pumps water and collects air at a part.

An air pipe 4 is communicated with and connected to a first head part 1. A first pipe 3 is communicated with the first head part 1, and an upper end thereof is formed to discharge water inside of the first branch container 8. The first branch container 8 and the second head part 14 are communicated with each other through a communication pipe 12. A second pipe 23 communicated with and connected to the intermediate water intake part 16 is formed to discharge water inside of the second branch container 24. A first upwelling pipe 9 and a second upwelling pipe 25 are respectively open-connected to lower parts of the first branch container 8 and the second branch container 24.
