SUS304 Buried Fire Water Storage Tank for Large Capacity Underground Installation
Buried Fire Water Storage Tank
,SUS304 Underground Storage Vessel
,Large Capacity Underground System
This buried large-capacity stainless steel fire water tank is specifically engineered for fire-fighting water reserve projects in residential communities, industrial factories, commercial malls, hotels, and municipal engineering applications. The tank body utilizes thickened SUS304 stainless steel stamped modular plates, designed for full underground burial to conserve above-ground space without occupying green land or parking areas.
With exceptional pressure resistance, anti-rust properties, and anti-leakage performance, it ensures stable long-term storage of large-volume fire reserve water, fully complying with international fire protection water supply standards. This solution addresses challenges of insufficient fire water storage capacity and limited ground space, making it the preferred buried fire water storage facility for new construction, reconstruction, and expansion projects.
- Main Plate Material: Thickened SUS304 stainless steel, providing corrosion resistance and rust prevention, maintaining integrity during long-term groundwater contact
- Plate Structure: Stamped arc reinforced panels with internal pull rod tension reinforcement, offering strong compressive resistance to withstand soil backfill pressure
- Sealing System: Food-grade anti-aging rubber sealing gaskets between plates, featuring double-layer anti-seepage design to prevent underground water leakage
- Auxiliary Accessories: Complete with fire inlet, fire outlet, overflow port, sewage drain, liquid level monitoring interface, manhole inspection well, and anti-floating anchor base
- Optional Configurations: External anti-corrosion coating, underground reinforced concrete bearing base, and remote liquid level monitoring module
The complete tank system is buried beneath building green belts, parking lots, or road surfaces, supported by specialized concrete bearing bases and anti-floating anchor structures to counter underground buoyancy and soil pressure. The tank maintains fixed fire reserve water year-round, directly connecting to building fire pump rooms and fire pipe networks.
During fire alarm activation, fire pumps extract water from the tank to supply fire hydrants, sprinkler systems, and firefighting equipment. The enclosed buried structure prevents water evaporation, dust contamination, and winter freezing, ensuring consistently sufficient and clean fire water reserves throughout the year.
- Underground Buried Installation, Space Saving: Complete underground burial eliminates ground space usage, preserving community landscaping, parking, and commercial layouts while meeting construction and municipal engineering requirements
- Strong Compression & Anti-floating Structure: Reinforced stamped panels with internal tension pull rods, combined with anti-floating anchor bases, withstand backfill soil and vehicle load pressures while preventing tank floating and deformation from underground water buoyancy
- Excellent Anti-corrosion & Long Service Life: SUS304 stainless steel resists groundwater acid and alkali corrosion, preventing rust and water seepage with normal service life exceeding 30 years—significantly longer than traditional concrete buried fire tanks
- Large Customizable Storage Capacity: Modular assembled structure allows capacity customization from 10m³ to 2000m³, suitable for small residential areas to large industrial parks and municipal centralized fire water reserve projects
- Low Operation & Maintenance Cost: Closed storage reduces water evaporation loss; smooth stainless steel interior walls minimize algae and sediment growth, requiring only periodic simple sewage discharge inspections with minimal daily maintenance
- Fast On-site Assembly & Short Construction Period: Standard prefabricated stainless steel modules manufactured in factories and transported for direct on-site splicing significantly reduce civil construction cycles compared to concrete fire pools
