R-Tank® Stormwater Modules

Underground Modular Stormwater Storage

MODULAR SYSTEM OVERVIEW

R-Tank stormwater modules provide an efficient and versatile underground stormwater storage system to assist with stormwater detention, infiltration and rainwater harvesting applications. With 95% void space, this system will allow you to reduce your underground stormwater storage system footprint to resolve utility conflicts or free up space for a future expansion. Due to the patented design of the system, it is one of the most efficient systems on the market and is a cost-effective alternative to stormwater basins and other underground systems.

Five different module configurations (LD, HD, SD, UD & XD)  provide module options from 2” to over 7’ tall. In addition, R-Tank delivers support for HS-20 and HS-25 traffic loads, with cover depths ranging from 6” to over 16’.

A critical component of any R-Tank design is the geotextile fabrics used to wrap the tanks. The fabrics used can change the application. For instance, R-Tank can be designed to discharge the stormwater runoff into a drainage system, release the stormwater back into the ground, or contain the water for future use.

Specifications, case studies, installation instructions, maintenance guides, drawings and more can be found below.

HYDROCAD STORMWATER MODELING SYSTEM

R-Tank systems can be easily modeled with the HydroCAD® Stormwater Modeling system, allowing simplified analysis of the system’s behavior in a drainage and stormwater management system. HydroCAD includes custom rating curves for these devices, which can be used with the “special outlet” capability to easily define the device’s stage-discharge characteristics.
