Effective rainwater collection protects the underground tank by controlling leaves, sediment and other debris before runoff reaches the PP storage modules. Pre-treatment and accessible maintenance points are essential for stable long-term system operation.
System role and suitable projects
This page focuses on rainwater catchers, filters and maintenance rather than the storage module alone. The appropriate treatment train depends on whether runoff comes from roofs, paved areas or landscaped catchments.
- Roof systems needing leaf and sediment control
- Paved catchments requiring silt separation
- Reuse tanks requiring upstream water-quality protection
- Projects needing accessible inspection and cleaning points

How the modular tank works
Runoff first passes through screens, catch pits, silt traps or filter chambers selected for the source. Treated flow enters the modular tank, while access points allow accumulated debris to be inspected and removed on a planned schedule.
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.
