What is a raw water tank? A raw water tank is a heavy-duty storage vessel used to hold untreated water from natural sources—such as rivers, wells, or rainwater—before it undergoes purification or industrial processing. As a critical component of water infrastructure, these tanks must offer exceptional corrosion resistance to handle varying mineral content and provide structural integrity for massive volumes. Center Enamel’s bolted steel tanks (GFS and FBE) are the industry standard for scalable, leak-proof raw water containment.
Raw water storage requires a balance of speed, durability, and cost-efficiency. Center Enamel’s modular technology provides distinct advantages over traditional concrete or welded alternatives:
● Glass-Fused-to-Steel (GFS): Our signature technology fuses glass to steel at 820°C-930°C. The resulting inert surface is resistant to a wide pH range (1-14), making it ideal for raw water with high turbidity or mineral aggressive profiles.
● Fusion Bonded Epoxy (FBE): Developed with AkzoNobel, this coating provides excellent impact resistance and UV durability, ensuring a maintenance-free service life of over 30 years.
As a global leader, Center Enamel has pushed the boundaries of bolted tank engineering. Our modular design supports single-tank and cluster configurations with capacities ranging from 20 m³ to 60,000 m³+, meeting the needs of massive municipal and industrial intake systems.

Bolted tanks offer factory-controlled quality, ensuring that the internal coating is applied uniformly without the risks associated with field-painting. They are also faster to install and can be expanded if demand increases.
Yes. Every raw water tank is custom-engineered to meet local seismic activity, wind loads, and snow loads in accordance with AWWA D103-09 and Eurocode standards.
Absolutely. Our tanks are certified to NSF/ANSI 61, WRAS, and FDA standards, ensuring that raw water storage does not introduce contaminants into the treatment chain.
