Comparing with the rigid tank(like steel tank or poly tank), the potable bladder bag is a better way for storage and transportation:
- size 25gal to 250,000gal（100L to 1,000,000L), custom available.
- highly resistant to puncture and UV resistant.
- economical: less half than steel tank.
- no limited on space, the shape can fit any space.
- no height when empty, low profile when filled.
- can be folded, when empty.
- can be packed in small package.
- less weight, easy shipping.
