PROBLEM TO BE SOLVED: To provide on-land installed-type intake equipment which enables water intake and water discharge to be performed by means of a submerged pump, and which can be easily relocated. SOLUTION: This on-land installed-type intake equipment 1 comprises: a water intake tank 7 which is installed on land, and in which water is to be sucked from a water intake area via a suction pipe 4 and stored; the submerged pump 6 which is internally installed in the water intake tank; a discharge pipe 8 which is connected to the submerged pump so as to discharge the water stored in the water intake tank; an intake pipe 9 which branches off from the suction pipe, which communicates with an upper part of the water intake tank above a branch position of the suction pipe, and which is opened in the water intake tank; and an injection pipe 10 which is included in the intake pipe with a gap between the injection pipe and the intake pipe, and which is extended toward a water intake tank-side opening of the intake pipe. Air in the suction pipe is sucked into the water intake tank via the intake pipe by emitting a jet of water flow into the water intake tank from the injection pipe, so that the inside of the suction pipe can be decompressed. The water is sucked in from the water intake area by the suction force of the suction pipe put into a negative-pressure state, so that the water stored in the water intake tank can be discharged by means of the submerged pump.
