PROBLEM TO BE SOLVED: To provide a vacuum valve unit which can also be easily installed, for example, in a private building lot with a small installation space. SOLUTION: This vacuum valve unit 1-1 is equipped with: a sewage pit 20 into which wastewater from a house flows so as to be stored therein; a vacuum valve 11 which is connected to a vacuum pipeline 17; an opening/closing controller 13, a sensor pipe 14 and a vacuum sluice valve 17, which serve as attachments of the vacuum valve 11; and a suction pipe 12, one end of which is arranged in the sewage pit 20 and the other end of which is connected to the vacuum valve 11. The vacuum valve unit 1-1 opens the vacuum valve 11 so as to suck up the wastewater in the sewage pit 20 by a vacuum suction force of a vacuum pipeline 17 and transfer the wastewater through the vacuum pipeline 17. The sewage pit 20 is a building sewage pit which is buried under the ground in the building lot, and the vacuum valve 11, the attachments of the vacuum valve 11 and the suction pipe 12 are housed and arranged in a storage case 10 which is installed on the ground in the building lot.
