The water intake tower 200 has a bottom embedded in the sea floor and protruding above the seabed surface. The seawater flows in through the water intake port 201 at the upper part of the water intake tower 200, and the inflowed seawater flows through the piping inside the water intake tower 200 Flows vertically downward and flows into the water intake pipe 210 buried in the sea floor. The inflowing seawater is transferred to the land or another place through the water intake pipe 210 to undergo a desalination process.

It is preferable that the water intake tower 200 is formed at an appropriate depth to obtain a smooth water intake and good quality seawater. For example, the intake port 201 of the water intake tower 200 should be located at a predetermined distance (at least 4 m or more from the sea level) from the sea surface so as not to be affected by the wave height, and sand and foreign matter And may be formed at a position of at least 2 m or more from the sea floor so as not to be influenced.
