The Atlantis Flo-Tank® is a underground water tank system, designed to provide versatile and efficient solutions for various water storage needs. This modular system enables the construction of water reservoirs with unlimited capacity, customizable in multiple shapes and depths to meet the demands of different terrains and project geometries. By wrapping the tank’s outer surface with PVC or Polyethylene membranes, watertight underground volumes are created, allowing stored water to be used later for irrigation, commercial, residential, industrial reuse, or even firefighting networks.

Unlimited Capacity and Customizable Design

The Atlantis Flo-Tank® offers the flexibility to construct water reservoirs of any size, adapting to the specific requirements of your project. Its modular design allows for easy expansion and customization, ensuring that the system can meet the unique demands of various terrains and geometries. This adaptability makes the Flo-Tank® an ideal solution for projects of all sizes, from small residential installations to large industrial applications.

Efficient Water Storage and Reuse

When wrapped with PVC or Polyethylene membranes, the Atlantis Flo-Tank® creates watertight underground volumes. These sealed tanks efficiently store water, which can be later utilized for a variety of purposes. Whether for irrigation, commercial use, residential applications, or industrial processes, the Flo-Tank® ensures that water is readily available when needed. Additionally, this system can support firefighting networks, providing a reliable source of water in emergencies.

Sustainable and Profitable Solution
