R-Tanks


R-Tank® Modular Stormwater Storage System
R-Tank® is a high-capacity, underground stormwater storage system designed for detention, infiltration, and water harvesting. Its modular design allows for flexible configurations that maximize land use while supporting traffic loads and meeting site-specific depth constraints.

Features:

  • Modular system with stackable units from 2″ to 10′ tall
  • Five strength-rated models: LD, HD, SD, UD, XD (30 to 320 psi)
  • 95% internal void space (90% for XD) for maximum storage efficiency
  • Supports HS-20 and HS-25 traffic loads with cover depths from 6″ to 16.5′
  • 90% open face area for enhanced infiltration and exfiltration
  • Manufactured from post-industrial recycled polypropylene
  • Lightweight components—no cranes required for installation
  • Compatible with pretreatment systems like Trash Guard Plus®
  • Can be installed under parking lots, roads, athletic fields, and landscaped areas

Benefits:

  • Reduces system footprint and avoids utility conflicts
  • Increases usable land area for development
  • Enhances groundwater recharge and reduces runoff volumes
  • Adapts to shallow groundwater or deep cover conditions
  • Speeds up installation and reduces labor costs
  • Durable and chemically resistant for long-term performance
  • Ideal for both new construction and retrofit applications
  • Supports sustainable design and LEED goals

Applications

  • Underground detention and infiltration
  • Water harvesting and reuse systems
  • Bioretention and dry well retrofits
  • Parking lots and roadways
  • Athletic fields and playgrounds
  • Green infrastructure and LID projects
