Collect and reuse rainwater! Large-capacity "Underground Rainwater Tank."
A large-capacity rainwater tank is a "home dam"! As the capacity increases, the uses expand as well!
■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!
