With our drinking water underground tanks you are on the safe side in the long term: the tank material is polyethylene (PE) which is suitable for drinking water and which, thanks to its elastic properties (200% breaking strain) can withstand major pressure. Thanks to its monolithic construction method (made in one piece) settling cracks and water loss due to penetrating roots can be ruled out. That’s why our tanks remain 100 percent watertight and why we provide a 25 year guarantee on the tanks.
Their light weight and low installation depth mean the drinking water tanks are easier to install than other containers. Filling gravel can be used as backfilling material. You can also undertake a range of work steps to make installation cheaper.

Please always use together with a VS 60 shaft extension and walkable or driveable tank cover (see “Accessories” under rainwater usage.)

Drinking water tanks are available in 6 sizes between 1500 and 10000 litres, colour black (see below of dimensions and weight).
