Burgoin-Serena is a French company with a hundred years of tradition in the production of tilts.

Our leading products include flexible tanks.


Flexible tank allows storage of different types of liquids:

  • Storage of drinking water, rainwater, sewage and liquid fertilizers. The tanks are made of PVC-coated polyester canvas with a fabric weight of 900 g/m² to 1400 g/m² depending on the volume and subject matter of storage.
  • For fuel, tanks are made of special polyester canvas coated with Alcryn with a fabric weight of 1300 g/m².
  • Tanks for drinking water are made of material which is KTW- Ionesco certified. This certificate is issued by organizations which are approved by French and German states. The material fabric weight is 1100 g/m².

Take, for example, a standard 5 m³ tank for non-drinking water and well water for watering, irrigation and washing.

The folded tank dimensions are 50 cm x 50 cm x 40 cm.
The dimensions after unfolding are as follows: 5 m long, 2.3 m wide and 0.7 m maximum height.

Components for flexible tanks vary with the type of use and location of the tank.


For a 5 m³ tank, the following additional components are needed:

  • Corner reinforcement plates.
  • DN146 valve for checking and cleaning the empty tank.
  • Bypass valve DN25 for checking the water level in the tank.
  • Side inlet and drain valve – for filling and emptying the tank with flange, flange block DN50 and DN50 with brass inlet valve.


Advantages of Flexible Tanks:

  • Simple and quick installation anywhere -in the field, in the cellar of the house.
  • Possibility to move on any means of transport at any time.
  • The tank is 100% tight, the liquid does not evaporate and does not change its volume.
  • Tank volumes from 300 litres to 1,000,000 litres.
