Aluminium Water Tanks

Aluminium water tanks give you durable, corrosion-resistant storage that holds up where steel struggles. Made from a marine-grade aluminium alloy, they suit coastal sites, exposed locations, and any industrial environment where corrosion is a real concern. They are commonly used for fire protection, process water, and general industrial water storage on UK and international sites. 

What Are Aluminium Water Tanks? 

An aluminium water tank is a site-assembled storage tank built from a marine-grade aluminium alloy with a tailor-made internal liner. The aluminium shell gives the tank its corrosion resistance and structural strength, while the internal liner is matched to the liquid being stored. Available in a wide range of diameters, heights and capacities, the design suits projects from compact installations to large-volume storage.

Aluminium Water Tanks for Fire Protection 

For fire protection use, aluminium tanks act as pump suction tanks for sprinkler systems and as stored water reserves for fire-fighting. Their corrosion resistance makes them well-suited to long-term water storage where reliability is essential. Our fire protection tanks include an aluminium Firestore® range built to the standards of the fire protection industry, with site assembly designed for ease of installation and low ongoing maintenance.

Aluminium vs Galvanised Steel Water Tanks 

Both materials are proven for industrial water storage, but the choice comes down to the environment and the budget. Galvanised steel offers a robust, cost-effective shell with excellent corrosion protection in standard conditions. Aluminium goes a step further in harsher environments, particularly coastal or marine-tropical sites where airborne salt accelerates corrosion. Both tank types use a tailor-made liner inside the shell, so the stored water is always separated from the structural metal.

Where Aluminium Water Tanks Perform Best 

Aluminium water tanks are designed for conditions that test ordinary storage solutions. Coastal sites, marine-tropical climates, and exposed industrial locations all benefit from the alloy’s corrosion resistance. They can also be specified for sites subject to high wind speeds and seismic load conditions. That makes them a sensible choice for international projects and challenging UK sites where standard tanks would have a shorter service life.

Sizing and Installing an Aluminium Water Tank 

Aluminium water tanks are site assembled from prefabricated panels, so they can be delivered to most locations and built in place. Diameters, heights, and capacities are tailored to your project, with the design accounting for site access, load conditions, and water demand. Use our tank capacity calculator to size the tank against your stored water requirement, then talk to our team about layout, foundations, and the right liner specification. Like the rest of our bespoke water tanks, every aluminium tank is configured to the project rather than pulled off a shelf. 

Why Aluminium Water Tanks Are a Sustainable Choice 

Aluminium is fully recyclable, and the tank shell is built to last for decades, which keeps replacement and disposal cycles low. When the time comes, the liner can be replaced without rebuilding the tank, and our tank refurbishment services extend the asset’s life further. That combination, durable material, replaceable liner, and refurbishment over replacement, line up with the circular economy principles we apply across the product range.
