Silent Vacuum Drainage System

The Silent Vacuum Drainage System solves your drainage problems!

The Silent Vacuum Drainage System is... When installing toilets or similar facilities in a basement, it is common to have a sewage tank and use a sewage pump for a pressurized system. However, a minimal amount of sewage often remains in the tank, leading to unpleasant odors. Additionally, when trying to install toilets or water facilities in existing buildings, it can be difficult to ensure proper usage conditions and the slope of the drainage pipes on lower floors, which may lead to abandonment of the project. To address these issues, a vacuum-based drainage system has been devised as an alternative to the pressurized system. However, many systems apply a vacuum sewage system that uses lift-up support and gas-liquid mixed suction, which has caused problems with noise and vibration. This system is a Silent Vacuum Drainage System that resolves noise and vibration issues by using a method that does not involve air suction. Model demonstrations are available for viewing.

Introduction of case studies for the Silent Vacuum Drainage System (2)

Even if there are no drainage pipes nearby and the piping route is uneven, drainage is still possible! (At a certain station building)

**Renovation Case at a Certain Station (Shizuoka Prefecture)** (1) Requirements We wanted to drain the station office, platform shop, and restaurant, but there were no drainage pipes nearby. (2) Specific Reasons for Hindrance to Requirements The drainage pipe route to connect to the drainage pipe was uneven, making it impossible to use a pump-up system. (3) Specific Design We adopted an SVD system to suction drainage to the platform with a drainage pipe. ▼ Vacuum Unit - System Decision Due to space constraints, we adopted the non-continuous suction I-2 type vacuum unit. - Installation Location Decision Installed on the existing drainage pipe platform with a fenced enclosure. ▼ Vacuum Pipeline - Route Decision The installation route was planned only through the uneven piping route under the train tracks. - Vacuum Tube Consideration A vacuum tube (pipe) was installed independently from the vacuum unit. ▼ Detection Pit - Installation Location Decision Station Office: 450×450×400H Platform Shop: 350×350×350H Restaurant: 350×450×550H - Capacity Consideration Since there is one vacuum collection tank, we planned the suction water level and alarm water level to ensure no disruption to drainage even when the system is stopped.

Introduction of case studies for the Silent Vacuum Drainage System (3)

No need to secure pipe slope, making long-distance drainage possible! (Inside a certain station)

**Example of Renovation at a Certain Station (Kanagawa Prefecture)** (1) Requirements We want to remove the standalone treatment septic tanks that process wastewater from two facilities within the station and discharge directly into the public sewer. (2) Specific Reasons for Hindrance to Requirements The inflow pipe to the standalone treatment septic tank is too low, making it impossible to secure the necessary slope for discharging into the public sewer located about 150 meters away. Additionally, redoing the outdoor piping would require extensive earthworks, resulting in high construction costs. (3) Specific Design We adopted the SVD system and implemented above-ground piping without any earthworks, except for the detection chamber. ▼ Vacuum Unit - System Decision Considering cost-effectiveness and installation location, we chose the I-2 type. - Installation Location Decision Outdoor installation close to the public sewer. ▼ Vacuum Pipeline - Route Decision Piping laid above ground along the boundary fence of the property. - Vacuum Tube Consideration Since uneven piping was anticipated, it was planned independently from the vacuum unit. ▼ Detection Chamber - Installation Location Decision Installed in the space after the removal of each facility's standalone treatment tank. - Capacity Consideration To ensure a wastewater inflow of 100 liters during a system downtime of approximately 2 minutes, a height of 0.5 meters was secured between the suction water level and the alarm water level.
