Daiwa Kasei's "Rainwater Tank" is a system that collects rainwater at home, allowing for storage and purification, effectively utilizing rainwater. Don't you think it's wasteful to use drinking water for toilet flushing? By installing a rainwater tank, a family of four using the RTN-60F (5,600 liters) can cover over 70% (approximately 50,000 liters) of the approximately 73,000 liters of water used for toilets in a year. Installing these tanks in each household serves as a temporary flood control measure during heavy rain, helping to mitigate damage from sudden increases in water levels. [Features] ■ Underground installation type (large capacity) ■ Easy capacity expansion by connecting multiple tanks ■ Water-saving effect ■ Measures against localized heavy rain such as guerrilla downpours *For more details, please refer to the PDF materials or feel free to contact us.

■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!
