A rainwater catchment-to-storage system connects the surfaces that receive rainfall with conveyance, pre-treatment and an underground modular tank. Good design starts with catchment area and rainfall data, then matches storage volume and discharge or reuse requirements.
System role and suitable projects
The page focuses on the relationship between catchment and storage. It is useful when project teams need to translate roof or paved-area runoff into a practical modular tank volume and connection layout.
- Roof and podium catchment systems
- Schools and small commercial developments
- Landscape irrigation storage
- Mixed catchments requiring coordinated pre-treatment

How the modular tank works
Rainfall is collected from defined surfaces and conveyed through gutters, drains and filters to the modular storage tank. The selected outlet, pump or overflow then manages stored water according to the reuse and drainage strategy.
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.
