Storage and Equipment Labaronne-Citaf FAQs

your questions about STORAGE OR EQUIPMENT FOR FLEXIBLE tank

The following FAQ lists practical information concerning storage conditions or the technical characteristics of Labaronne-Citaf’s flexible tank equipment.


The thickness of a technical fabric depends on its coating. Its thickness is generally between 0.7 and 1.2 mm. Consisting of a weave that ensures its reinforcement, the thickness of a technical fabric does not really matter. Other parameters to consider include its breaking strength and elongation at break.

The choice of our fabrics is made both by our experience and by the technical characteristics of the liquids likely to come into contact with the coating. This is why we have an extensive range of technical fabrics to meet the specificities and storage conditions that may be required of us. For example, we store manure in flexible tanks whose technical fabric is different from that used for water storage.

The valve support avoids the mechanical stresses on the technical fabric that could be induced by the weight of an equipment (valve + pipe…).

The overflow is a safety hole positioned on top of the tank. When your tank is full, the excess water drains out through the overflow. Be careful, as soon as liquid flows from the overflow, it is imperative to stop filling the tank.

If your flexible tank is installed in a crawl space, it is possible to connect the overflow to an outlet.

In France, departmental health regulations, the nomenclature of classified installations or other local regulations may make retention mandatory regardless of the volume of liquid fertilizer stored. Usually, it is advisable to find out about local regulations. It is strongly recommended to use a retention device to recover the fertilizer in the event of an incident and to avoid contamination of the natural environment.


A flexible tank is self-supporting because of its construction and the materials used. It is used for the storage of liquids only, occasionally or temporarily.

Regulations may vary from country to country or region to region. In France, the majority of these are departmental regulations called the RDDECI. Some circulars include dimensioning elements and other national recommendations, but departmental regulations are often the most detailed. These are written by the Departmental Fire and Rescue Service. For this reason, it is advisable to contact local contacts when you have a construction, rehabilitation or extension project (e. g. SDIS in your department for fire tanks).

In France, local regulations as the Health Regulations (“R.S.”) of the departments or the Nomenclature of Classified Installations (“I.C.P.E.”), may govern the storage procedures for potentially polluting products. Generally, it is advisable to find out about local regulations.

Yes, some of our products made with specific technical fabrics are suitable for this type of storage. Contact our sales department to find the best way to meet the technical specifications of your project.

D.E.C.I. Labaronne-Citaf tanks are designed to meet the requirements of firefighters. Our fire tanks are subject to numerous points of vigilance in accordance with the QB certification and the NF standard to which we are attached. All the equipment used is standardized and perfectly meets the connection requirements of firefighters. In the event of a fire, firefighters can therefore quickly connect to our fire reserves.

It varies according to the volume of the tank and the materials chosen to make it. Our sales department will advise you on the best solution according to the nature of your project.

The technical fabrics used for our flexible tanks incorporate an anti-UV treatment in their formulation. We have experience feedback on tanks installed in the desert or exposed at high altitudes to high UV radiation and which are still in use after decades of exposure. We have other tanks in France that have been in operation for more than 20 years!

The liquid stored in a flexible tank is in contact with all the walls of the tank. The fabrics used are completely opaque, so there is no photosynthesis or development of filamentous algae. It is possible that a biofilm may be created on the tank walls (as on pool liners) but this will not prevent the tank from being used.

To estimate the volume of useful water to be stored in your flexible tank, several criteria are necessary. You must take into account the rainfall in your area, the collection area and type of roof, your average water consumption per year and the number of people living in your household. To help you define the necessary volume, we have at your disposal a calculation aid sheet. You can download it here.
