A large unit measuring "2,650mm × 3,700mm," which cannot be accommodated in standard sizes, has been installed with a mechanical bath. To fit the large mechanical bath, the dimensions of the bathroom were maximized as much as possible. The three sliding doors were arranged to be drawn back against the wall, ensuring an opening dimension that maximizes the width of the passage. This is a case of a new installation in a hospital.

• Toilet

■This is a water recycling system that purifies, decolorizes, and deodorizes wastewater from toilets and kitchens, allowing it to be reused as toilet flushing water. ■Thanks to a system that uses ozone, the treated water becomes colorless and odorless. ■By purifying and reusing water, it eliminates waste of resources and perfectly aligns with the concept of "environmental consideration and coexistence"! ■Even during water shortages or disasters, as long as power is secured, toilets can be used, so there is no need to worry about toilets during droughts or earthquakes. ■In areas with discharge restrictions, a no-discharge system can be implemented, allowing the gray water reuse system to be effective! ■In the gray water reuse system, water is treated in three stages: "combined treatment septic tank → tertiary treatment tank → gray water treatment tank," ultimately purifying the wastewater to below "BOD5 mg/liter" and above "transparency 100"! ■There are implementation records in convenience stores, small to medium-sized suburban stores, factories, and more. ■A maintenance contract is required.

• Water Treatment

■If you have an underground rainwater tank, it can store up to 5.6 tons of rainwater! ■Let's use it for gardening irrigation, toilet flushing, car washing, and save water! ■If you want to make full use of rainwater, a large-capacity underground type is recommended! By storing a lot of rainwater, the range of uses expands. ■Generally, the water used for one toilet flush is about 6 liters for large toilets and 5 liters for small toilets, which amounts to approximately 54,000 liters per year for a family of four. By installing a rainwater tank, you can cover about 55%! This translates to about 29,700 liters saved annually! ■If many households install rainwater tanks, it can also help reduce sudden increases in river water levels during heavy rains. ■If you need a capacity of more than 5.6 tons, custom production in FRP is also possible!
