Preassembled for Immediate Installation: Delivered fully assembled, Carat Tanks streamline the installation process, saving time and reducing labour costs. This feature ensures that the tank can be quickly and correctly set up, allowing immediate operation upon delivery.

Optional Vehicle Loading Lid: Carat Tanks offer an optional vehicle loading lid to accommodate installations under surfaces such as driveways where space is at a premium. This lid allows the tank to bear significant weight, providing flexibility in tank placement without compromising safety or functionality.

Moreover, fully compatible tank domes, risers, and lids address varying invert-level requirements, enhancing adaptability and ease of integration.

Watertight Seal Assurance: All connections between the tank dome, riser, and lid include high-quality thick rubber gaskets, ensuring watertight seals that protect against leaks and environmental contamination.

Flexible Backfill Options: Depending on ground conditions and groundwater levels, Carat Tanks can be backfilled with either granular material or concrete, offering flexibility to meet site-specific requirements and ensure optimal installation integrity.
