Underground stormwater containment, detention, retention, and harvesting

One Rainstore³ unit measures 1 m x 1 m x 0,1 m high (3.28 ft x 3.28 ft x 4 inches high). 94% void space provides nearly 25 gallons of water storage per unit.

The Rainstore³ units are encased in a geotextile filter fabric. Three layers of geogrid add support. A maintentance port, a pretreatment filtration system, and an outlet pipe are common elements. Click to see an enlarged view.

Stackable and modular, many different configurations can be achieved for your site. This site shows Rainstore³ cell stacks at 24 high.

Rainstore³ is a modular and stackable structure used to store stormwater underground. Made from injection molded plastic, a single panel contains 36 vertical columns and exceeds H-20 loading, allowing the construction of driving areas, parking lots, or other small structures above the system. Built-in compression fittings allow units to be easily stacked to a variety of depths up to 7.9ft pr 2.4 meters.

Benefits

Allows development of valuable land resources by moving stormwater ponds below ground
Available Pre-Assembled in Depths from 4" to 7.9 ft (2.4 m)
94% Open for Water Storage
Eliminates Stone Requirements
Easy Installation

Applications

Underground Stormwater Storage
Detention or Retention Systems
Water Harvesting

The Rainstore³ modular system is more efficient at storing and recharging water than arched chambers and corrugated plastic or metal pipe. Rainstore³ is less expensive than concrete vault chamber.
