"More than 25,000 infiltration basins for rainwater discharge" is a rainwater storage infiltration method that allows rainwater to permeate underground, solving urban flooding issues and achieving water circulation.
The "EMBX2 series" is a permeable polycon basin that can be freely combined to match the height of GL, inflow pipes, outflow pipes, etc., thanks to its rich variety of options. It has a water storage capacity of approximately 0.72 m³ per unit at maximum size, and in sandy soil conditions, it demonstrates an infiltration capacity of about 1.60 m³ per hour. Additionally, it features a structure that is resistant to shifting, making it easy to connect with other infiltration facilities. 【Features】 ■ Processes rainwater with a large infiltration surface ■ Capable of recovering infiltration capacity *For more details, please download the PDF or feel free to contact us.
