This manufactured PP water harvesting module is a repeatable structural component for assembling underground rainwater and stormwater tanks. It is produced as an individual module rather than a finished stand-alone vessel, allowing project teams to build storage volumes from multiple units.
System role and suitable projects
The page focuses on the manufactured component itself: material, module dimensions, nominal volume, packing and integration into an engineered tank system.
- OEM and distributor sourcing of PP tank components
- Modular rainwater retention and reuse tanks
- Stormwater attenuation structures
- Projects requiring scalable unit-based storage

How the modular tank works
Manufactured modules are assembled into the approved tank geometry and combined with side components, wrapping materials, pipe connections and inspection provisions. The final system specification—not the module alone—determines installation depth, traffic suitability and hydraulic performance.
Installation planning
- Confirm runoff volume, design storm, inflow and discharge requirements.
- Check excavation, groundwater, soil bearing conditions and required cover depth.
- Prepare a level base and assemble modules according to the approved layout.
- Wrap the structure with the specified geotextile and/or waterproof membrane.
- Connect inlet, outlet, ventilation, inspection and overflow components.
- Backfill in controlled layers and commission the system before operation.
Packing and project support
| Detail: | Size | Packing |

Module quantities and container loading should be confirmed from the final tank geometry and current packing plan. Leiyuan can review project volume, module layout and shipping requirements for professional buyers.
Information required for a quotation
Send the project location, required storage volume, application, installation depth, surface load, groundwater level, drawings and delivery destination. This allows the module and system build-up to be checked before quotation.
