Makeup Water Storage Tank Manufacturer Serving France: EN 1090, NF and Local Compliance

A makeup water storage tank manufacturer serving France must deliver EN 1090 execution class compliance with a declaration of performance and CE marking for the structural steel, design to ISO 28765 for the glass coating where used, and a lining (GFS or FBE) with a chemical-resistance list matched to the water chemistry. We have real French deliveries, a potable-water GFS tank in Guadeloupe, France (2024, phi 16.05 x 6 m), a biogas CSTR GFS tank in France (2021, 2,215 m3), and a corn silo project in France (2023, 1,663 m3), which prove our ability to deliver coated bolted tanks into France, though none are data-center makeup projects.

Structural steel tanks placed on the French and EU market must meet EN 1090 with the correct execution class and carry CE marking through a declaration of performance. Confirm the manufacturer holds the EN 1090 certification and can issue the declaration per project, because this is the gate to legal placement on the EU market.

• EN 1090 execution class.
• CE marking via declaration.
• Gate to EU market.
• Confirm per project.

For a glass-coated tank, ISO 28765 governs the enamel system and the design of the glass-fused-to-steel structure; for epoxy, the FBE system is qualified with a holiday test and chemical-resistance list. The Guadeloupe potable tank (France, 2024) used GFS, demonstrating our French-delivered coated-tank capability.

• ISO 28765 for GFS.
• FBE holiday + resistance.
• Guadeloupe GFS 2024.
• Chemistry-matched lining.

French engineers and utilities may reference NF standards and local requirements for water and construction; the manufacturer should be able to map its EN and ISO basis to those expectations and supply French-language documentation where needed. The France CSTR (2021) and corn silo (2023) show our broader French project history.

• NF mapping where required.
• French-language docs.
• CSTR France 2021.
• Corn silo France 2023.

A French makeup water tank for cooling is clean treated water, often non-potable, so NSF/ANSI 61 is not the governing standard unless potable; the lining must resist the cooling-tower treatment program. Size follows evaporation, drift, and blowdown at the site, with autonomy margin. The table contrasts European versus general compliance.

• Usually non-potable, not NSF 61.
• Lining resists treatment.
• Size by tower losses.
• Autonomy margin.

We have delivered real coated bolted tanks into France, the Guadeloupe potable-water GFS tank (2024), the France biogas CSTR (2021, 2,215 m3), and the France corn silo (2023, 1,663 m3). These are genuine French deliveries, but they are potable-water, biogas, and silo applications, not data-center makeup projects, so we present them as evidence of French-delivery capability, not as data-center makeup cases.

• Real France deliveries.
• Guadeloupe / CSTR / silo.
• Not data-center makeup.
• Evidence of French delivery.

A makeup water storage tank manufacturer serving France must operate inside the European frame, EN 1090 execution class with CE marking and a declaration of performance, ISO 28765 for a glass coating or a qualified FBE system, and French-language documentation where required, while a makeup tank for cooling is usually non-potable so NSF 61 is not the governing standard. We have real French deliveries, the Guadeloupe potable-water GFS tank (2024), the France biogas CSTR (2021, 2,215 m3), and the France corn silo (2023, 1,663 m3), which prove our ability to deliver coated bolted tanks into France, but they are potable, biogas, and silo applications, not data-center makeup projects, so we present them honestly as French-delivery evidence rather than data-center cases, and we can map our EN and ISO basis to NF expectations for your project.
