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.

**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.

**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.

【Case Study of Adoption at a Certain University (Kanagawa Prefecture)】 (1) Requirements Renovation of the men's restroom on the first floor. (2) Specific Reasons for Hindrance to Requirements There is no underfloor pit, and all existing piping is laid in the ground, necessitating floor demolition work. Additionally, the renovation is desired during the summer vacation, but due to school events, the actual construction period is limited. (3) Specific Design Adopted an SVD system, with toilets and urinals using lining booths for above-floor drainage. ▼ Vacuum Unit - Decision on System Since it is a school, the restroom will be used intensively during breaks. Given the high frequency of use, a continuous suction type "C-2 model (drainage capacity 80L/min)" was adopted. - Decision on Installation Location Installed close to the outdoor drainage manhole and surrounded by a safety net fence. ▼ Vacuum Piping - Decision on Laying Route Planned with exposed piping in the ceiling area of the first floor. - Consideration of Vacuum Tube Extracted from the top of the vacuum piping after the vacuum drainage valve. ▼ Detection Manhole - Decision on Installation Location Divided into two zones for suction, with four sets of toilets and other areas. - Consideration of Capacity The toilet side is 450×450×400H (suction volume approximately 36.5L), and the urinal side is 500×450×310H (suction volume approximately 16L).

Introducing the Sanipump Series (Compact Pressure Drainage System) and SVD (Silent Vacuum Drainage System). Do you have any of the following concerns? - Want to add a gym but can't create a shower room... - Unable to install a toilet near the beds in a nursing facility and had to give up... - Complaints arose due to odors from temporary toilets during construction... - Relocating water facilities requires floor demolition work... Using a system that does not require a slope can solve these issues. ■ Sanipump Series This is a system that 'pressurizes' drainage using the power of a pump. We offer a wide range of products suitable for general drainage, sewage, and even commercial facility applications. ■ SVD (Silent Vacuum Drainage System) This is a system that uses 'vacuum' power to suction drainage. It can accommodate multiple fixtures and large capacities, and does not require power on the drainage fixture side. By using a method that does not suck in air, it also resolves noise and vibration issues. Of course, it is also possible to combine these two products.
