This 0.125 m³ PP rainwater storage module measures 680 × 410 × 450 mm and is used as a repeatable unit in underground retention, reuse or attenuation tanks. Eight legacy modules provide approximately one cubic metre of nominal module volume.
System role and suitable projects
The page focuses on the individual module dimensions and capacity. A completed tank requires multiple modules plus the specified wrapping, hydraulic connections, inspection access, base and backfill.
- Modular underground rainwater storage tanks
- Stormwater attenuation structures
- Infiltration tanks with permeable wrapping
- Non-potable reuse tanks with waterproof containment

How the modular tank works
Modules interconnect to form the approved tank geometry. The system designer determines the number of units from effective storage requirements, then checks cover, surface loading, groundwater, wrapping and access provisions.
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 |
