How it works

Similar to our standard Rainstore3 product, although engineered specifically for multi megalitre systems, Rainstore3 Advantage is designed to achieve major cost savings for very large projects with unlimited volume capacity.

Rainstore3 Advantage is a unique combination of Rainstore3 modules and internal vertical columns providing a simple construction designed to maximise excavation to storage ratio, maximise storage volume (98% void) and maximise cost effectiveness.

Depths of up to 2.8m in 100mm increments can be achieved with any footprint in one or half metre increments.
