More Details:

The Carat is a high-strength underground tank built from two half-sections that are joined in the field with a reliable gasket and clamping system. This design makes it possible to transport a tank to the job site in a small truck, and then hand-carry the components to the excavation. A swiveling top compartment called a dome provides ample space for inlet, outlet, and filtration components. A telescopic riser slides into the dome and provides height adjustment so that the access lid can be positioned flush with the ground surface.

Carat tanks can be fully emptied for long periods without danger of collapse. With an extension and a heavy-duty riser, they can be buried up to 48” below grade; with a heavy-duty riser and a cast-iron lid they can be used under residential driveways and parking areas.
