Process for making a modular, underwater, connection of water stretches, wherein the prefabricated modules from different manufacturing yards, freely floating in the water area in front of a floodable basin, are introduced, one at a time, into the basin, through an upper door and, after the basin is emptied, are laid on support saddles. The modules are then aligned and connected with the end of an already installed length, and, after flooding the basin again, are launched by being butt-pushed by means of a driving system, guided by means of thrust roller units.
