R-Tank Stormwater Modules provide efficient and versatile underground storage for stormwater detention, infiltration, and rainwater harvesting. Not to mention, with up to 95% void space, R-Tank optimizes underground storage depth and footprint. As a result, it solves utility conflicts and frees up space for future expansion.

R-Tank provides system height options from 2 inches to over 7 feet tall. It also accommodates HS-20 and HS-25 loading with cover depths as little as 6" and as deep as 16'. R-Tank solves tough stormwater problems by adapting to the needs of your site–whether you are designing a project with shallow ground water or deep cover conditions.

• Check the plans to ensure the R-Tanks® are running in the correct direction (north/south vs. east/west) to match the footprint shown on plans (see Fig. 8). • R-Tank® units should fit together evenly.

R-Tank modules provide an efficient and versatile underground storage for stormwater runoff to assist with stormwater detention, infiltration and rainwater harvesting applications.

R-Tank is a lightweight, durable, and configurable solution for subsurface stormwater storage. The unit's high void space optimizes storage, reducing assembly, excavation and backfill requirements. The R-Tank Heavy Duty (HD) provides HS-20 load support with a minimum 20” of cover and can support a maximum 84” of cover.

If R-Tank units arrive on your project in flatpanels, they will need to be assembled. Complete directions are provided below, and there is a video available by searching YouTube for “R-Tank assembly” or by using this link: https://www. youtube.com/watch?v=0MTzTVkTq5Q. Building the modules should take 2-3 minutes per segment.

A. R -Tank - Injection molded plastic tank plates assembled to form a 95% void modular structure of predesigned height (custom for each project). B. R-Tank units shall meet the following Physical & Chemical Characteristics:

R-Tank stormwater modules provide underground storage for runoff. These tanks are used in detention, infiltration and rainwater harvesting applications. R-Tanks offer 95% efficiency, making them the optimal choice when the project needs to make a small footprint.

R-Tank systems are a type of underground modular storage system. When units are combined, they form a system that provides high void space (95%) stormwater storage for flood mitigation, detention, and infiltration applications. These systems can be outfitted with Treatment Rows to provide treatment of stormwater influent.

R-Tank stormwater systems provide underground storage of stormwater. After a rain event fills the R-Tank, storm-water 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, infil-
