Fuel tank cleaning — diesel, petrol, heavy fuel oil

Fuel tank cleaning is a legal obligation for petrol stations, petroleum product depots and industrial facilities with internal fuel systems. Sediment, water and bacteria that build up in the tank degrade the fuel and damage the system.

Fuel tank cleaning
in North Macedonia

Fuel tank cleaning is a legal obligation for petrol stations, petroleum product depots and industrial facilities with internal fuel systems. Sediment, water and biofilm that build up in the tank damage the fuel, clog filters and shorten the tank's life.

Our team works with all types of tanks — above-ground (AST) and underground (UST), with capacities from 5,000 to 100,000+ litres. We have ADR certification, training and atmospheric monitoring equipment. Every job follows a full safety procedure.

We also offer fuel sampling before and after cleaning — the 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 are asked most often

How often should a fuel tank be cleaned?
It depends on usage — petrol stations once a year, industrial tanks with lower turnover 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 a 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 returned after cleaning?
Yes, after sampling and laboratory analysis — if the results confirm its quality.
