Abstract

A water intake pit includes a first plate-like member (17) extending in a direction from a rear wall toward the upstream side of water flow while being put in water and which has an upper surface (17a) facing a lower end (38A) of a suction port (38), wherein the first plate-like member (17) is set to partition a first flow passage (26) with an inner bottom surface (11a) of the pit body (11), and a second plate-like member (18) extending in the direction from the rear wall toward the upstream side of the water flow while being put in the water and is positioned above the suction port (38), wherein a second flow passage (27) is formed between the first plate-like member (17) and the second plate-like member (18), and a third flow passage (28) through which the water is flowed is formed on the second plate-like member (18).
