Onion Tank for holding water is a self-supporting open-top flexible water tank designed for temporary water storage, firefighting reserve, irrigation, livestock water, emergency response, and outdoor project use. It is made from reinforced PVC-coated fabric, with capacity, tank diameter, height, fabric thickness, inlet, outlet, drain valve, color, and packing method customized according to the application.
The onion shape allows the tank to stand when filled without a fixed frame, while the open top supports quick filling from hoses or pumps.
It is useful for small farms, remote worksites, landscaping, fire-prevention staging, and temporary water supply.
Compared with rigid tanks, an onion-style flexible tank is easier to fold, transport, store, and deploy.
