Most Effective Method Is Removal and Disposal

There may come a point in a homeowner’s life when the underground tank is not required because oil is no longer the source of heating. Most oil tanks are decommissioned in situ, but there are occasions when this is not the case. The most effective method of decommissioning is to remove and dispose of the tank. The removal process will usually begin by cleaning the tank, followed by lifting it, if it’s an external tank, then cutting it into sections to remove it. An excavation may be necessary should the tank be underground.

When a tank has to be decommissioned in place, the first move is to pump out any remnants of water and oil. An expert will use a shovel to dig to allow the top of the tank to be exposed. An opening is then formed by cutting, and the interior is cleaned out well. Any sludge remaining is pumped out.

Samples of soil are collected and screened, and if the results come back and show that no leaks are present, then the cavity can be filled up with gravel and the soil replaced. If the samples reveal a leakage, then a clean-up operation should be carried out by experts.

Removal can sometimes be the preferred option. Often, soil contamination can be a problem, and the tank will require removal so that the contaminated area can be accessed.

Experts Can Provide the Service from Start to Finish

There are many companies which provide a professional tank decommissioning service, including www.ashremediation.co.uk/tank-decommissioning.

Similar to decommissioning an oil tank, removal requires excavating to the roof of the tank – then the experts will slice it open with appropriate machinery and thoroughly clean out the interior.

According to Katu2, hidden oil tanks buried on properties may emit fumes that could cause cancer.

One point worth noting is that it’s essential that the tank is cleaned out meticulously before it is removed. Once the cleaning process has been completed, the tank is then removed from its position and transported for recycling. Once again, soil samples will be taken from the excavation to ascertain if any leaks have occurred. The excavated site is then filled with gravel and the soil replaced, resulting in a complete restoration of the site.
