The invention relates to a seawater desalination tower which is constructed on pile piers in the sea at sites along the coast at a depth of between 10 and 20 metres. The inventive tower comprises a cylindrical base (1) which rests on pile piers (10) which in turn rest on an annular raft (11) which, depending on the type of soil, can rest on piles (12), said base (1) being disposed at approximately 10 m above maximum sea level. The tower is generously flared at the base (1) thereof, narrows gradually toward the neck (2) and then flares out toward the apex (3). The neck has an inner diameter of approximately 100 m for a 300 m-high tower and is disposed at an approximate height of 140 m. The apex (3) has an inner diameter of approximately 130 m and comprises an annular platform (4) with an approximate width of 15 m, on which wind turbines of approximately 1.5 MW each are installed. A second platform (5) is disposed slightly above the neck (2) and said two platforms are supported by ribs (6 and 7). Moreover, a condenser assembly is disposed above the neck (2) inside the tower. For storm protection purposes, the tower is partially or totally surrounded by a breakwater wall which is constructed on pile piers and which is disposed at a distance that is at least equal to the radius of the base of the tower, water being able to pass through multiple holes.
