The new tank generation of Carat rain-water underground tanks have been specially developed for rain-water harvesting.

http://www.graf-water.com/rainwater-harvesting/general-information/video-carat-assembly.html

The GRAF Carat S underground tank is unlike any other underground tank in the world. It is the largest tank of its kind to be manufactured by injection compression moulding.  This technique provides the tank with unbeatable stability and ensures that each component is produced with the highest of
accuracy.  Unlike other underground tanks, the wall thickness is equal in all areas of the tank.  The production tolerances are kept to a minimum, resulting in a product of the highest quality, which is strong, accurate, reliable and extremely
user-friendly.  To manufacture the Carat S range, one of the worlds largest injection moulding systems had to be developed.

Easy and safe assembly

  • The quick connection allows the Carat tank to be assembled without screws in only few minutes. Disassembly is possible at any time.
  • The first-class EPDM material used in the profile seals, has been laboratory tested to last more than 25 years.
  • The centering bolt assures the accurate and easy assembly of the two half shells preventing any leaks

More advantages

  • Variable burial depth: 30" to 42" (59" Max. with optional dome extension and "Maxi" telescopic riser)
  • Unique in the world! – a global innovation: unique manufacturing process produces the highest stability due to latest techniques
  • Unique fit accuracy of the components thanks to new production process
  • Consistent quality due to TÜV safety testing and production monitoring
  • Vehicle-bearing (with telescopic cast iron manway kit)
  • Groundwater stable up to the middle of the tank due to extremely rigid construction
  • Secure investment with market leading 15-year warranty
  • Made from high quality Duralene; easy to recycle
  • Can be expanded as required
  • 31.5" Manway opening

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 five 1,700 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.
