"Hydro Staff" is a plastic rainwater storage and infiltration tank that is buried underground, featuring a plastic void storage infiltration facility that temporarily stores rainwater and facilitates infiltration treatment to control runoff. With over 1,500 installations and a total storage capacity exceeding 400,000 m³, it has been highly evaluated by various sectors. 【Features】 ■ Our original sediment control system ensures the long-term functionality of the storage tank. ■ Excellent strength and seismic resistance allow adaptation to various environments and locations. ■ Equipped with large testing machines and inspection facilities in our own factory. ■ Raw material production is also conducted in-house with thorough quality control (ISO 9001 certified). ■ The column-beam structure provides ample space within the storage tank to hold a large amount of rainwater. *For more details, please refer to the PDF document or feel free to contact us.

• Flood prevention facilities, fire tanks, and flood control ponds
• Septic tank equipment

The "Stick Filter" is a vertical rainwater infiltration facility that maximizes its capabilities in a compact space, useful in various scenarios from municipal flood control measures to addressing local rainwater issues. By lifting the collection cup, it is possible to collect the sediment that has accumulated at the bottom, making maintenance easy and helping to maintain the infiltration effectiveness of the facility. 【Features】 ■ Efficient infiltration capacity due to its vertical design ■ Can be installed in a compact space ■ Excellent maintenance performance ■ Can be constructed by anyone using general-purpose machinery ■ Reliable technology with public technical certification *For more details, please refer to the PDF document or feel free to contact us.

• Piping materials (plastic pipes)
• Piping materials (concrete pipes)

The "Bunker Drain" is a product designed to solve the problem of water accumulation in bunkers, featuring a large upper filter and a non-woven fabric (i.e., permeable sheet) that minimizes the risk of clogging and makes maintenance easy. If there is a sand and gravel layer beneath the clay layer, it is possible to reach this layer by using intermediate extension materials or PVC pipes, thereby improving drainage performance. 【Features】 ■ Easy to install with pinpoint accuracy ■ Does not significantly impact play or operations during installation or maintenance ■ If buried deeply, the water head pressure increases the infiltration performance ■ Low risk of clogging ■ Maintenance is also easy *For more details, please refer to the PDF document or feel free to contact us.
