Product Description

Semi Vacuum Drainage System

The semi-vacuum and semi-sewage lifting system provides the possibility for the subsequent expansion of the station. The semi-vacuum sewage system can completely solve all sewage discharge in the station and provide the possibility for subsequent transformation and expansion. Especially in the renovation project of the old subway station, the use of a semi-vacuum sewage system can solve the problem of difficulty in sewage discharge by adding a new drainage point in the basement.
