SAVIFLEXITANK self-supporting flexible tanks are economic, ecological and easy-to-install systems designed to collect and store water and other liquids for many different uses.

For example:

Agricultural sector/fertilizers and livestock slurry
Drinking water storage
Waste/leachate collection
Water treatment/storage systems
Fire water reserves (firefighting)
Bioenergy/digested product
Water reserves for irrigation
Chemical industry
Water purification plants

The flexible tank is also the ideal product for those who are sensitive to ecology and environmental protection, as well as for those on a budget.
Our tanks don’t need any permit nor building licenses to be installed. In addition, they don’t need any maintenance over time, since they are made of materials that withstand extreme weather conditions. Just make sure that the operating pressure inside the tank does not exceed 0.5 Bar.

SAVIFLEXITANK flexible tanks are all made in Italy, through a production system patented by the Company, using high-tenacity polyester fabrics of European origin only, coated with PVC on both sides and provided with an anti-UV treatment. In the event of temporary usage, they are collapsible and can be stored where space is limited.
They come in various sizes and capacities and, on specific request, they can hold up to 500 m3.
According to the need and the usage, the tanks can be fitted with different types of valves, pipes, hydraulic gate valves, vents and drains. Various colours are available depending on specific usage.
