How It Works

Rainstore3 is not pipe or arched chamber, but a structure with strength throughout its shape. The unique design places the plastic entirely in compression rather than bending or tension resulting in H-20 loading, and high void storage volume of 94%! Minimum cover is only 0.3 meter.

The structure can be as shallow as 0.1 meter or as deep as 2.5 meters, length and width in 1 m increments. Rainstore3 eliminates site restrictions by conforming to custom project requirements. RS3 does not require any stone backfill between structures. Calculating the void (storage) volume is as simple as dividing storage demand by 94%. This means significant savings in amount of excavation, soil transport, imported stone, installation time, and labor.

Rainstore3 can be utilized for long-term water storage for irrigation, fire protection, and potable applications by encasing the structures in an impervious liner. Porous lining materials around RS3 offer 100% surface area coverage for water infiltration/exfiltration.
