Flexible Drinking Water Tank — certified for human consumption.
2.000 to 1.000.000 litres. Food-grade PVC/polyester laminate. Above-ground installation. DN50.
Hidrostation's flexible drinking water tank is made from PVC/polyester laminate certified for direct contact with water for human consumption. Inert, odourless, with no chemical migration. It installs above ground with no excavation at all — foldable for transport, ready to use in hours. Available from 2.000 to 1.000.000 litres with DN50 connections as standard.
Why the Flexible Drinking Water tank?
Unlike concrete cisterns or rigid buried tanks, the flexible drinking water tank installs above ground in a matter of hours, with no building work and no heavy machinery. The material — PVC/polyester laminate certified for food contact — ensures the stored water picks up no odours and is not contaminated by chemical migration. Ideal for domestic reserves, communal supply in remote areas and emergency reserves.
The 2 DN50 connections included as standard fit into any drinking water distribution network. Where the installation is permanent, the underground connection option lets the pipework be buried without dismantling the tank. The 5 to 10-year manufacturer's warranty and a service life of over 20 years make this an economical, dependable choice for projects of any size.
