Fire water storage tanks provide a reliable and cost-effective solution for securing sufficient firefighting water where public hydrants, water networks, or underground cisterns are unavailable, insufficient, or uneconomical.
Our focus is on above-ground, flexible / mobile fire water storage tanks designed for temporary or permanent fire protection concepts.

What Is a Fire Water Storage Tank?

A fire water storage tank is a dedicated water reservoir used exclusively for firefighting purposes. It ensures that the required extinguishing water volume is available on demand, independent of public water supply limitations.

Flexible above-ground systems are increasingly used as an alternative to underground concrete cisterns, especially where speed of deployment, cost efficiency, or relocatability are critical.

Typical Applications

Fire water storage tanks are used in a wide range of sectors, including:

• Industrial and commercial facilities
• Logistics centers and warehouses
• Energy infrastructure (PV parks, wind farms, substations)
• Municipal and rural fire protection concepts
• Construction sites and temporary buildings
• Forestry areas and seasonal wildfire risk zones
• Agricultural and remote installations

Key Advantages

Above-ground, flexible fire water storage tanks offer clear technical and economic benefits:

• Capacities from small volumes up to several hundred cubic meters
• No excavation or underground construction required
• No permanent soil sealing or concrete foundation
• Fast installation and commissioning
• Significantly lower investment costs compared to concrete cisterns
• Relocatable and reusable if site conditions change
• Suitable for temporary or long-term use

Depending on local regulations and duration of use, these systems may be classified as mobile or temporary installations, which can substantially simplify approval procedures.

Temporary or Permanent Use

Flexible fire water storage tanks can be integrated into both:

• Temporary fire protection concepts
  (e.g. construction sites, seasonal wildfire protection, interim solutions)
• Permanent fire protection concepts
  (e.g. industrial sites, logistics hubs, remote facilities)

Suitability for permanent use depends on project-specific requirements and acceptance by the responsible authority or fire brigade.

Fire Water Volume & Sizing

Required fire water volumes are typically defined by local fire protection concepts and depend on:

• Fire risk classification
• Required flow rate
• Duration of firefighting operations

Illustrative example:
1,600 l/min × 120 minutes = 192,000 liters (192 m³)

Fire water storage tanks can be sized modularly to meet these requirements.

Approvals & Regulatory Context

Fire water storage tanks are generally assessed on a case-by-case basis by local authorities and fire services.
Unlike underground concrete cisterns, above-ground flexible systems are not automatically governed by a single uniform standard.

Relevant considerations may include:

• Fire water demand and accessibility
• Vehicle access and suction points
• Temporary vs. permanent installation duration
• Local building and fire protection regulations

Early coordination with authorities is strongly recommended.
Final approval always lies with the responsible fire brigade or permitting authority.

Maintenance & Operation

Flexible above-ground fire water storage tanks are designed for low-maintenance operation:

• No corrosion or concrete degradation
• No confined-space inspections
• Simple visual checks of material, fittings, and connections
• Easy access for inspection and cleaning

This results in lower lifecycle costs compared to underground cistern solutions.

Advantages Compared to Underground Concrete Cisterns

• Faster implementation
• Lower total cost of ownership
• No excavation or groundwater interference
• No permanent land sealing
• Easier relocation or removal
