Flush with ground level (2 seals)
The Carat S underground tank has numerous seals to effectively stop dirt getting into the tank. This means that seepage water cannot get into the tank and, thus, dirt particles cannot contaminate the rainwater. The seals are in the intersection between the tank and the tank dome and between the tank dome and the telescopic dome shaft. All supply pipes connected to the tank dome are also sealed with five lip seals as standard.

 

Application:

  • The global innovation – the new tank generation of the Carat rainwater underground tanks have been specially developed for rainwater harvesting
  • Frost-proof installation underground
  • Groundwater stable up to the middle of the tank due to extremely rigid construction

 

 

The tank that turns its head for you

The GRAF Carat S underground tank has a rotating tank dome. The tank dome can be aligned with the connections independently of the tank – this makes installation much easier! All installation pipes are connected using the five standard lip seals. The Carat S telescopic dome shaft connects the system to the ground surface. The height of the tank can be smoothly adjusted to suit the local conditions and it can be tilted by 5°. The whole system is flush with ground level.

 

Logistical advantages of the Carat:

The Carat tank consists of two half shells which can be stacked on top of each other, allowing multiple tanks to be stacked on a single pallet for shipping. For example, it is possible to stack seven 1,000 gallon Carat tanks on a single pallet. This allows a standard 40 ft. shipping container to house a total tank volume of up to 34,000 gallons! The tanks' unique stacking feature directly reduces transport costs and environmental impact from vehicle emissions.

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.
