,Underground Stormwater Geocellular Module
This underground interlocking recycled polypropylene rainwater storage module is a practical, space-saving rainwater harvesting solution specially optimized for residential rain reuse projects. Built from robust recycled PP material, these interlocking rainwater storage crates snap together horizontally and vertically, letting homeowners and installers customize underground storage tanks to fit backyard layouts, garden spaces and limited excavation zones, replacing bulky concrete tanks with a lighter, easier-to-install alternative.
Featuring a high void ratio open-cell structure, the interlocking rainwater storage modules capture roof runoff and surface rainwater efficiently. The stored rainwater can be filtered and reused for lawn watering, garden irrigation, car washing, toilet flushing and other non-potable household applications, cutting mains water consumption and lowering domestic water bills. As a key part of residential sustainable drainage design, it helps reduce stormwater runoff, ease local sewer overload and minimize flood risks around houses.
