RainTank Modular Plastic Stormwater Storage System

RainTank Modular Plastic Stormwater Storage System (MPSS) provides underground storage of storm water in retention, detention and infiltration applications. (Link directly to RainTank Case Studies) (Link directly to RainTank Downloads)


1. RainTank is a sub-surface water storage structure that provides up to 90% of the excavated area for water storage volume. Applications include stormwater detention, retention and harvesting.


2. The assembled RainTank quad module.


3. The excavated area is prepared.


4. Geotextile or liner and RainTank units are placed into prepared excavated area.


5. Structural fill, geogrid, compaction and final cover finish the installation process.


6. RainTank's 95% void space requires minimum excavation depth and footprint for maximum storage capacity.


7. RainTank's modular design provides…


8. ...flexibilty in applications from shallow (39"/3.25 w-cover) to deep (107"/8.9' w-cover).


9. RainTank can be built around utilities or other infrastructure.


10. RainTank's modular design allows for easy field changes. In the example above higher than expected ground water forced a field change from 3 rows of penta units to four rows of quad units.


11. RainTank's lightweight panels are freight friendly and units can be shipped assembled or unassembled.


12. The lightweight, assembled RainTank units can be placed by hand - eliminating the need for equipment to transport and place the storm water storage system.


13. RainTank's open matrix allows for higher infiltration flow rates both into and out of the system.


14. RainTank's open matrix allows for connection flexibility. Pipes can be connected at virtually any spot on the system.


15. RainTank is a self contained system that requires no manifolds or connections that can be hard to estimate and can slow down delivery and field operations.


16. RainTank's system approach using specific cover thickness and geogrid provides H-20 load support.


17. Utilizing RainTank storage in an "on-lot" approach can reduce the need for storm water basins, eliminating safety, maintenance and aesthetic concerns.


18. The RainTank system can be encapsulated in a PVC liner for storm water harvesting applications (fountains, restrooms, irrigation, etc.).


19. A number of LEED credits can be attained by using RainTank.
