Vacuum pump 11 sucks the air in the vacuum sewer pipe 7,
The inside of the vacuum sewer pipe 7 is depressurized. The sewage discharged from the house 1 flows into the sewage tank 3 through the natural flow pipe 2. When a certain amount of dirty water is accumulated, the air in the dirty water amount detecting pipe 12 is pressed, and this air pressure is transmitted to the controller 14 through the gas introducing pipe 13, and when the pressure exceeds a certain pressure, the controller 14 is operated to open the vacuum valve 5. Then, the sewage is sucked from the vacuum valve suction pipe 4 due to the differential pressure between the atmospheric pressure in the sewage mist 3 introduced in the air supply pipe 16 and the vacuum pressure in the vacuum sewer pipe 7,
It flows through the vacuum valve 5 to the vacuum waste water pipe 6 and the vacuum sewer pipe 7. Further, air introduced from the atmosphere communicating with the dirty water 3 is sucked from the vacuum valve suction pipe 4, and is sucked into the vacuum sewer pipe 7 through the vacuum valve 5 and the vacuum dirty water pipe 6. The air that has entered the vacuum sewage pipe 6 and the vacuum sewage pipe 7 expands and becomes a mixed flow of sewage and air, and is collected in the water collection tank 9 of the vacuum pump station 8. The air in the water collection tank 9 is a vacuum pump 11
And the water collection tank 9 is maintained at a constant vacuum degree. The sewage collected in the water collection tank 9 is sent to the pressure pump 1
0 is sent to a sewage treatment plant.
