Maximum Water Storage with Modular Engineering

The Aquascape AquaBlox Large is the flagship of the modular water storage system (also known as D-Raintank by Atlantis). At 32 gallons per unit, it's designed for larger pondless waterfalls, commercial rainwater harvesting, and high-capacity underground storage applications that demand maximum water retention in minimal space.

Triple the Storage Capacity of Traditional Methods

AquaBlox holds 7.4 gallons of water per cubic foot—over three times more than gravel's 2.2 gallons per cubic foot. This superior storage density means smaller excavations, reduced labor costs, and less material handling. The lightweight modular design makes installation quicker, safer, and cheaper than traditional concrete or gravel systems.

Multiple Applications Beyond Water Features

These versatile modules work for pondless waterfalls, RainXchange rainwater harvest systems, constructed wetland systems, and pump wet wells. The underground storage and infiltration design produces clean water that can be reused or safely returned to natural water systems.

Built for Heavy-Duty Applications

Strong enough to support patio stones, decorative rocks, and heavy landscape elements. The load-bearing design handles up to 5,472 pounds per square foot while maintaining structural integrity. Each unit ships flat-packed and assembles on-site with included top, bottom, two sides, and four structural supports.

Reduced Maintenance, Superior Performance

AquaBlox are easier to clean and less prone to clogging than gravel-based systems, reducing long-term maintenance and eliminating the constant topping-off required with traditional reservoir designs.
