Fuel tank cleaning — diesel, petrol, heavy fuel oil

Fuel tank cleaning is a legal requirement for petrol stations, petroleum product depots and industrial sites with in-house fuel systems. Accumulated sediment, water and biofilm in the tank damage the fuel, clog filters and shorten the tank's service life.

Fuel tank cleaning
in Serbia

Fuel tank cleaning is a legal requirement for petrol stations, petroleum product depots and industrial sites with in-house fuel systems. Accumulated sediment, water and biofilm in the tank damage the fuel, clog filters and shorten the tank's service life.

Our team works with every type of tank — above-ground (AST) and underground (UST), with capacities from 5,000 to 100,000+ litres. We hold ADR certification, are fully trained and have atmospheric monitoring equipment. Every job follows a complete safety procedure.

We also offer fuel sampling before and after cleaning — samples are analysed in accredited laboratories. The results form part of the official documentation. For commercial clients — monthly and quarterly contracts with priority response.

Questions
we get most often

How often should a fuel tank be cleaned?
It depends on throughput — petrol stations once a year, industrial tanks with lower throughput every 2-3 years.
How long does cleaning take?
An above-ground tank of 10,000-50,000 L — 1 day. An underground tank of similar size — 1-2 days, because access is more complex.
Does the tank have to be emptied?
Yes, the tank must be emptied before the team goes in — we transfer the fuel to a transport vehicle.
Which gases are measured?
Oxygen (min 19.5%), explosive gases (LEL), toxic gases (H2S, CO). Continuously throughout the work.
Can the fuel be put back after cleaning?
Yes, subject to sampling and laboratory analysis — if the results confirm its quality.
