Flo-Tank® Modular Tank System

The Flo-Tank® is a structural lightweight modular tank system used to construct underground water storage for various applications. The modular nature of the system allows for the easy construction of tanks of any volume and can be designed to accommodate specific site conditions.


  • Infiltration / Absorption Tanks
  • Rainwater Harvesting Tanks
  • Stormwater Detention / Attenuation Tanks / O.S.D Onsite Detention
  • Underground Stormwater Channels
  • Underground Drainage
  • Lightweight Structural Fill

Total Stormwater Management

Modular tank systems use surface and underground infiltration techniques, resulting in clean water that can be re-used or allowed to re-enter the natural water system. Modular tank systems offer a highly efficient option for stormwater management in any kind of soil.

Water Quality

Modular tank systems excel when there is a requirement to achieve high water quality, particularly in the effective removal of nutrients and gross pollutants. In addition to the obvious environmental benefits, the sub -surface location of the tank system provides more useable ground area and enhanced aesthetic setting compared to above ground concrete or plastic tanks.

The Modular Advantage

Modular tank system performance supersedes outdated aggregate trenches. The system provides a void space of over 90% compared to less than 20% in typical aggregate trenches. Consequently, with a smaller footprint the system achieves the same storage capacity as an aggregate trench. This saves time and money in installation and civil works costs. The lightweight design of modular tank modules also make installation quicker, safer and cheaper. No sediment build up occurs in the system, unlike the clogging that is characteristic of aggregate based approaches.
