When filled, the tank expands upward and outward, resembling the shape of an onion—hence the name Onion Water Tank.

This design offers several advantages:

• Fast setup without tools
• Open-top easy filling system
• Foldable and portable structure
• Space-saving transportation and storage
• High water storage efficiency in outdoor environments

The tank can be deployed within minutes, making it a preferred solution for emergency water supply, agricultural irrigation, and temporary construction site operations.
