VACUUM TYPE SEWERAGE SYSTEM

PROBLEM TO BE SOLVED: To provide a vacuum type sewerage system in which a valve for vacuum sewerage capable of showing a function as a gate valve (section valve), a function as a check valve, and further a function as an inspection hole is installed.SOLUTION: In the vacuum type sewerage system provided with a vacuum sewage pipe 1 including a multiple-stage lift, an automatic intake device is installed at an upstream side of the multiple-stage lift in the vacuum sewage pipe, which has an intake pipe 52 and a valve 51 and sucks air when a degree of vacuum in the vacuum sewage pipe decreases, and the valve for the vacuum sewerage having the function as the gate valve and the function as the check valve is provided at a further upstream side than the installation position of the automatic intake device in the vacuum sewage pipe 1. Thereby, when the automatic intake device opens the valve 51 and sucks air through the intake pipe, the system can prevent waste water from flowing back to the further upstream side than the installation position of the automatic intake device in the vacuum sewage pipe 1.
