Trays can alternate with each other with different pitch. At the same time the outer sides of all the trays and water intake grids are made with concave surface and form a single external water discharge channel. Water discharge chute is made of metal with central water discharge channel 6 and has blind concave surface of outer side of water discharge chute forming external water discharge channel 7. Water intake water discharge chute is made of metal and has central water discharge channel 6, is equipped with water intake grate 5 arranged in hole made from outer side of tray, wherein the outer sides of the tray and the grate are made with a concave surface and form a single outer drainage channel 7.

EFFECT: technical result is increase in water collection and removal efficiency; simplified maintenance of water disposal system; higher inter-revision period.
