  • Integrated filter technology with packages available

  • The tank's dome size is 80 cm, large enough to install filters with ease and to clean and maintain
  • Groundwater-stable up to the tank shoulder thanks to smart design
  • Easy transport due to low weight
  • 12-year warranty

The 1,500 L tank measures just 210 x 120 cm and the height to the tank shoulder is just 70 cm. (See image above.) The low tank height allows it to be installed without slope angles and therefore in a very small pit. Since the tank weighs in at just 80 kg, it’s easy for two people to install (see images).

Integrated filter technology

The professional, integrated filter technology is housed directly below the tank cover in the generously sized tank dome. It is based on the proven GRAF module system. An appropriate self-cleaning filter technology is supplied to match packages. Low maintenance requirements and high water yield are features. Remove the filter system without any tools if the tank needs to be inspected.

Attractive tank cover

The attractive tank cover can be telescoped and tilted as needed. Of the entire rainwater tank system, you will only see the discreetly designed cover, which sits flush with the lawn. There is also a child-proof lock and an internal water connection box.
