This is a floating pumping station, conceived as ordinarily to be used at the shore of the ocean or large lake where wave action is very considerable and where provision must be made for tidal change and in some cases change in the force of the waves since the waves of great amplitude must be refused entry into the apparatus or attenuated. The apparatus comprises, in brief, a pair of elongated pontoons which define a channel therebetween and this channel is guarded at one end at least by the said wave attenuating apparatus, while a plurality of double-acting pumps distributed along the length of the channel operate in response to the movement of floats which are connected to the pistons of the pump. The pumps have their inlets connected to a common filter sump wherein the water level is substantially that of the surrounding sea or lake, and a unique feature of the invention comprises a compartmentation of each pontoon, the compartments being distributed along the length of each pontoon and connected by a common conduit with stub pipes leading into each compartment and valved in such manner that float actuated water level controls in each compartment assure that the pontoons remain stabilized with respect to the water level in the filter sump which is the water level of the surrounding sea or lake.
