How do our above ground storage tanks work?

Our in-house design and engineering experts can provide you with purpose made tanks, tailor-made to your requirements and fully compliant with BS4994:1987.

Choose from a range of tanks, vertical, vertical bunded and horizontal cylindrical tanks, available with storage capacities from 1,000 litres to 250,000 litres.

Our manufacturing process also means we can customise your product, constructing wall thickness to suit the contents you wish to store as well as temperature adherence.

A range of customisation options allows you to specify access points, instrumentation, valves, inhibitors and more, to fully benefit from a truly bespoke system.

Please note, the Calona above ground storage tank is not intended for potable water. Visit our potable water tank page for solutions tailored to these needs.
