Drinking water tanks

testuje se additional info

Waterbase D Plus (TPU) and Waterbase D are flexible tanks designed for mobile and safe storage of drinking water in the field. Available in two variants, they differ in the type of material used and the scope of certification.

  • Waterbase D Plus is made of thermoplastic polyurethane (TPU)-coated fabric with extremely low particle migration. The tank is certified by the Polish National Institute of Public Health (PZH), ensuring it meets national standards for materials intended for contact with potable water. It also complies with BS 6920 and holds the WRAS certificate – a European quality mark confirming the hygienic safety and neutrality of the material in contact with drinking water.

Tanks allow for quick storage and distribution of water in areas lacking permanent infrastructure – such as construction sites, field camps, outdoor events, or emergency situations. They also serve perfectly as a backup water source for households.

Smaller models (up to 5,000 litres) weigh less than 35 kg and, when folded, fit in the trunk of a passenger car, making them easy to transport and set up by a single person.
