The above-ground polyethylene CB tanks are designed for the storage of foodstuffs, drinking water and rainwater (exactly like the CP tanks, CV tanks or CB tanks). The tanks are resistant to the effects of sunlight and can be installed in an uncovered area. Can be used at temperatures from -50 °C to +60 °C. Proper installation of the drinking water tanks in accordance with the manufacturer's recommendations guarantees protection against the growth of algae. Several chemical substances such as acids, alkalis, alcohols, etc. can be stored in the tanks (see resistance table for details).

The aboveground water tanks have a declaration of conformity with EC directive No. 10/2011 DT, 14/01/2011, 1935/2004 DT, 27/10/2004 and certified by the Polish National Institute of Hygiene.
