Collapsible water tank

Collapsible fire water tank

Collapsible firewater tanks with capacities of up to 2,000,000 liters have a wide range of applications, particularly in remote areas. They serve as a temporary or permanent supply of firewater for firefighting and as a water reserve, for example, in fighting forest fires . We offer special wastewater containment cushions for contaminated firewater upon request.

Flexible storage tanks for fire extinguishing water

The advantages of above-ground flexible storage tanks for firefighting water are:

  • Quick, easy and immediate installation.
  • No maintenance or intervention required.
  • Freestanding.
  • Constant water level: No evaporation or loss of volume.
  • Suitable as temporary fire-fighting water reserves.
  • Clean water without microalgae or larval growth due to the absence of light and air pockets.
  • No air pockets, therefore no oxidation problems.
  • No light penetration, no contamination: The water always remains perfectly clean.

(Upon request, we can also supply residue-free evaporating spray cleaner for degreasing, as well as elastic adhesive and drinking water-safe silicone grease from WEICON.)

Folding tanks as an alternative to fire ponds

The collapsible tank system is closed, meaning that, unlike fire ponds, there is no risk of drowning for children. Furthermore, the closed design prevents silt accumulation, significantly reducing maintenance. Extensive upkeep is unnecessary, making maintenance simple and cost-effective.

Technical specifications: The fire protection reservoir offers a reliable and adaptable solution for storing fire-fighting water. It is available in various sizes and can hold a volume of up to 2000 m³. Its design allows for quick and flexible installation. The reservoir is designed for a wide temperature range from -30°C to +70°C. This means the cisterns can be used reliably in extreme sub-zero temperatures down to -30°C as well as in hot summer temperatures. Even in freezing conditions, the water inside the fire-fighting cistern remains liquid and ready for use.

There are three connection options for the foldable fire water storage tank:
  1. Mobile, above-ground version for direct extraction (e.g. for temporary use or the risk of forest fires in summer) – with an additional optional heat-insulating valve heat protection sleeve that prevents the outlet valve from freezing at moderate sub-zero temperatures.
  2. Forest-free version with hydrant and suction connection with Storz-A connection ND100 (with underground pipeline to the hydrant)
  3. Frost-free version with connection to customer-provided underground pipeline

The frost-proof, underground extraction point (connection option 2 with hydrant or connection option 3 with customer-provided underground pipeline) ensures a reliable water supply at all times, regardless of the current weather conditions.

The bladder tanks store water (potable/non-potable), wastewater, fire-fighting water, fuel, and all types of liquids. These fire-resistant reservoirs are constructed from advanced technical fabrics that offer exceptional reliability and durability. Optimized for flexible use with large storage volumes, these fabrics can accommodate volumes of up to 2,000 m³. These unique storage systems offer high resistance and reliability.
