 Each Rainstore3 unit is only four inches (0.1 meter) high. At one or two units deep, Rainstore3 can be used to store water even in areas with extremely high water tables – places arched chambers or corrugated pipe will not work. |
 Rainstore3 is modular and can be stacked up to 25 units high (8.2 ft or 2.5 meters). Rainstore3 uses less of a surface footprint to store more water. 10.8 ft2 (one m2) of land can store up to 621 gallons (88.3 ft3 or 2.35 m3). Arched chambers and corrugated pipe cannot come close (see chart below). |
 Rainstore3 uses no stone in the excavated volume, saving in labor and trucking costs. Arched chambers and corrugated pipe rely on stone for much of their storage volume. Rainstore3 can use more than 75% of the excavated area available for water storage (see chart below). |
|
Rainstore3, used as a subsurface retention system , allows exfiltration of stormwater to recharge the ground water supply and natural aquifers. Exfiltration occurs through the bottom and all sides of the chamber. |
Rainstore3 can be used as a subsurface detention system to regulate the release of water into a sewer or off-site treatment facility and allows some exfiltration of stormwater. |
Rainstore3, used as a subsurface water harvesting system, collects rainwater (gray water) and reuses it for many non-potable applications, such as irrigation. |
