tank decommissioning

Need to upgrade a site but it has redundant fuel tanks that need to go?
Nqpetro specialises in tank decommissioning and the removal of underground fuel storage tanks Australia-wide.

Soil contamination resulting from leaks in underground fuel tanks is a growing problem as ageing underground steel tanks around the country begin to fail. Experts say hundreds of tanks are likely to fail over the next decade, particularly with the growing use of modern fuel blends that can corrode older tanks and fittings. In many cases, fuel retailers, industry and local councils are opting to change their fuel storage systems before problems arise.

If you’re considering replacing your underground tanks or changing your fuel storage configuration, it’s time to call in the experts in underground tank removal and decommissioning.

Why Do I Need to Decommission Underground Storage Tanks?

Having underground tanks professionally decommissioned ensures you meet all legal and environmental requirements.

Underground fuel tanks are a major source of soil and water contamination, which can lead to costly fines and remediation work.

If you are changing your fuel storage configuration, have bought a site which includes old underground tanks or a hoping to sell or change the use of a site containing underground tanks, you’ll need to have tanks professionally decommissioned. Many local councils are also working to have disused tanks under public land decommissioned and stabilised to prevent potential contamination that could affect soil and water and be a threat to public health.

Having underground tanks professionally decommissioned ensures you meet all legal and environmental requirements and don’t need to be concerned about surplus fuel leaking from tanks into soil as the steel corrodes with time – a common occurrence in tanks more than 20-30 years old. Decommissioning your older tanks also means you can install new double-walled tanks that comply with current environmental regulations and reduce the risk of leaks, or opt for above-ground storage options that area easier to monitor and maintain.

Ensuring your fuel storage systems are modern and environmentally compliant will not only reduce risk, but potentially add value to your business.

What are the Options for Decommissioning Underground Fuel Storage Systems?

Depending on the location of your tank and your future plans for the site, you may choose to have your tank decommissioned and left in situ, or to have it removed.

Our underground tank removal specialists at Nqpetro can provide professional advice for your situation, taking into consideration local, state and environmental legal and environmental requirements. We will oversee the removal and disposal of your underground fuel storage system and all associated infrastructure, including the removal and destruction of redundant tanks. In cases where tanks are left on site they are emptied, treated and filled with a stable foam that helps prevent structural collapse.

While every site is different, our tank decommissioning process can include:

Site survey and associated testing

Foam filling UST’s in Situ. Due to close proximity to Buildings, footings etc these cannot be physically removed
