Utilize water and store rain.

If you let it flow, it's a flood; if you store it, it's a "resource"! Suppress temperature changes in the building itself to reduce heating and cooling loads!

The "rainwater harvesting" indicated by the Japan Architectural Society's environmental standards emphasizes the importance of efforts towards flood control and disaster prevention. Our "water-utilizing rainwater harvesting" system utilizes rainwater as a water resource. Rainwater stored in an underground tank is drawn up by a dedicated pump from an intermediate water level (the part where water quality is stable) for everyday use. 【Features】 ■ Utilizes the blessings of rainwater as a water resource ■ Draws rainwater stored in the underground tank using a dedicated pump from an intermediate water level (the part where water quality is stable) for everyday use ■ Saves approximately 70m3 of tap water annually (according to our estimates) ■ Collected rainwater is brought into the underground tank as high-quality rainwater through a rainwater intake device that eliminates the dirty rainwater at the beginning of the rainfall *For more details, please refer to the PDF document or feel free to contact us.
