Flexible Raw Water Tank — irrigation, service water and firefighting.
2.000 to 2.000.000 litres. PVC/polyester laminate. Above-ground installation. DN50.
Hidrostation's flexible raw water tank is the quickest, most economical way to store irrigation water, industrial service water and firefighting reserves. Made from UV and weather resistant PVC/polyester laminate, it installs above ground with no excavation in a matter of hours. Available from 2.000 to 2.000.000 litres with DN50 connections as standard and a DOCX datasheet included with every model.
Why the Flexible Raw Water tank?
For agricultural irrigation and service reserves, the flexible raw water tank has a decisive advantage: no excavation, no concrete work, installation finished the same day. The PVC/polyester laminate withstands prolonged sun exposure and temperature swings without degrading. Foldable and light, it can be transported anywhere — including farmland with no access for heavy machinery.
The 2 DN50 connections included as standard link directly to drip irrigation, sprinkler or pumping systems. For wildfire fighting reserves, the larger models (800.000 to 2.000.000 L) can be installed and filled in a few hours. The 5 to 10-year manufacturer's warranty and a service life of over 20 years make it pay back over the long term.
