The Industry’s Gold Standards: AWWA D103 and EN ISO 28765
AWWA D103:
The American Water Works Association (AWWA) D103 standard is globally recognized for bolted steel water storage tanks, emphasizing:
Structural integrity for long-term water storage.
Resistance to chemical and environmental factors.
Rigorous design and manufacturing criteria to ensure safe, reliable operation.
EN ISO 28765:
The European Standard (EN ISO 28765) specifies the design, manufacture, and installation requirements for GFS tanks used for storing liquids. It highlights:
Robust glass coating to resist corrosion and wear.
Compliance with safety and performance guidelines for potable and non-potable water storage.
Assurance of high-quality production processes.
By adhering to these internationally recognized standards, Center Enamel ensures that our GFS tanks meet the most stringent quality and safety requirements.
