The PP Rainwater Collection Module is a core component of modern sponge city infrastructure. This system replaces traditional drainage methods by guiding rainwater through initial filtration in rainwater wells. A portion of the water is then stored in underground tanks for reuse in irrigation, street cleaning, car washing, and more. Once the tanks are full, excess water is safely discharged into natural water bodies.

Once the tanks are full, excess water is safely discharged into natural water bodies.
Large Capacity
The PP rainwater collection module is engineered with a high void ratio—typically over 95%—allowing it to store a large volume of water within a compact footprint.This reduces the need for extensive excavation and speeds up installation, making it ideal for urban drainage, sponge cities, and sustainable rainwater management systems.
Quick Locking Groove Design
The top and bottom modules use a fast-snap groove connection for tight, secure assembly and easy installation. The 16-point hot-runner injection ensures smooth joints without secondary cutting, delivering clean edges and seamless alignment.
Stackable Design
Featuring a 16-column layout with 2.8mm thick walls and a plum-blossom structure, the module offers high load capacity and over 95% effective void ratio. The integrated vertical alignment post ensures precise stacking and simplifies installation, while the stackable design reduces transport volume and cost.
Easy to Maintain
The module features an H-beam inspired internal frame for superior load-bearing capacity, 3D clamshell side panels for enhanced lateral pressure resistance, screw-type connectors to handle uneven foundations, and an independent flower-shaped top cover to allow soil backfill while protecting internal space. Together, these elements ensure exceptional strength, stability, and ease of maintenance.
