A method for installing and/or removing a cable ( ) in conduits ( ) for the passage of cables and to an associated implementing device. According to this method, a current of water is conveyed inside the conduits ( ), the cable ( ) to be installed has a conduit fill rate that can attain 90%, and the conduits ( ) form a winding course on a length greater than 2000 m. This method is chiefly characterized in that the cable ( ) is subjected to a thrust force that drives its speed of progression (v), and in that said thrust force and the pressure of the water flowing in the conduits are regulated so as to maintain a constant water flow rate inside the conduits ( ).
