To reduce a cost, to miniaturize individual buoys, and to optimally combine the buoys in a deep layer water recovering device.
This deep layer water recovering device is divided into a pump for pumping up deep layer water of the ocean through an intake pipe, a buoy of a pump function part having the function of driving this pump and a buoy of a utilization function part for utilizing the deep layer water; these are constituted so as to be mechanically or mechanically and electrically connected by a connecting mechanism; the buoy of the utilization function part has at least a water storate tank buoy; and the deep layer water pumped up by the buoy of the pump function part is sent to the buoy of this water storage tank buoy by a water supply means.
