PRODUCT OVERVIEW
The RainPro PP Modular Tank System is an advanced, high-strength underground water storage and infiltration solution engineered for modern stormwater management and rainwater harvesting. Constructed from recycled Polypropylene (PP), this modular system provides a lightweight, durable, and eco-friendly alternative to conventional concrete On-Site Detention (OSD) tanks and bulky metal storage units.
Designed with an open structural matrix achieving an extraordinary void ratio of >95%, the RainPro system maximizes underground storage capacity while significantly reducing total excavation volume, site labor costs, and installation time.
70% Faster Site Construction
Modular interlocking design allows extremely rapid assembly without long concrete curing waiting times, significantly reducing site labor and traffic disruption.
>40 t/m² Heavy Compressive Load
Engineered for high structural stability, suitable for installation under green lawns, pedestrian plazas, driveways, and heavy-duty car parks.
> 95% Void
Storage Ratio
Delivers over 95% void space, drastically minimizing total soil excavation volume and preserving valuable surface land area.
Dual-Function
(OSD & RWHS)
Configurable with permeable geotextiles for stormwater detention/infiltration, or impermeable geomembranes for zero-leakage rainwater retention and reuse.
