A water extraction facility comprising a suction box (4) having a suction opening (3) and communicating via a conduit (5) with a separator (6) separating air from water and having a top part, the top part of the separator (6) communicating via pipework (14, 15), on which is mounted a vacuum pump (8), with a chamber (9), disposed above the suction opening (3) and opening out towards the suction opening (3) via a connector (21), characterized in that
- a perforated sheet metal element (24) creating head loss and having first perforations is mounted in the connector (21),
- the connector (21) is clamped to a channel (27) in which is mounted a honeycomb bundle (28) with cells, the dimension of the cells of said honeycomb bundle being greater than that of the first perforations of the perforated sheet metal element (24), and
- the perforated sheet metal element (24) is covered with a metallic web (30) that has a void fraction of between 25 and 50% and that has second perforations of which one dimension is smaller than those of the first perforations of the perforated sheet metal element.
