R-Tank® Infiltration System
R-Tank® stormwater systems provide underground storage of stormwater. After a rain event fills the R-Tank, stormwater can flow into the drainage system, infiltrate into the ground, or be reused. The system is an alternative to stormwater basins and a more efficient, space saving alternative to other underground systems for detention, infiltration, and recycling stormwater.
R-Tank is a modular system and can be assembled to a variety of heights from 2” to just under 7’. This rigid system can be placed beneath a variety of surfaces including: Parking Lots, Streets and Access Roads, Driveways, Landscaping, Athletic Fields/Playgrounds, Swales and Channels.
R-Tank stormwater modules can be used for a variety of applications including: Retention and Infiltration, Detention, Recycling or Harvesting, Pond Retrofits, Dry Wells, and Bioretention. R-Tank stormwater systems have between 95% and 98% void space meaning a more efficient, space saving solution for detention, infiltration, and recycling stormwater.
Additional Benefits of the R-Tank System include:
- High Capacity
- Modular Design Footprints
- High Strength
- Increased Infiltration and Exfiltration
- Easy to Transport
- Lightweight and Quick to Install
- Permanent and Maintainable Storage Volume
The R-Tank is a modular system available in multiple configurations (LD, HD, SD, UD, and XD), to fit a variety of depth and loading requirements. And with an unlimited array of possible design layouts, the R-Tank can adapt to your project to make the most economical systems possible.
