How do below ground storage tanks work?

Our in-house design and engineering experts can provide you with pre-designed or purpose built below ground storage tanks that are fully compliant with BS4994:1987. 

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. 

Below ground storage tank maintenance

Protect your investment in your below ground storage tank by having it regularly inspected by Premier Tech. 

The frequency of service depends on the size of your tank, the type and amount of liquid stored, and the environmental regulations in your area. It is best to speak with us to determine servicing that is right for you.
