Underground storage tanks (UST) are among the most complex structures to clean. Restricted access (through the top only), potentially explosive atmospheres, limited room for the crew — all of this makes the job demanding.
Underground storage tanks (UST) are among the most complex structures to clean. Restricted access (through the top only), potentially explosive atmospheres, limited room for the crew — all of this makes the job demanding. It takes experienced teams, specialized equipment and strict protocols.
BioClean by EZO Green specializes in UST cleaning. Our team is fully trained for the work, and we hold all the required certificates (ADR, ATEX), atmospheric monitoring equipment and dedicated equipment for work in confined spaces. We work with every type of UST.
We are particularly experienced with USTs at petrol stations — typically 20,000-50,000 litres in capacity, with restricted access. We work night shifts or during planned shutdowns. Every job follows full safety protocols, including a standby team at the surface.
The complete package — biological products, certified team, documentation.
The most common type — diesel/petrol tanks at petrol stations.
Factories with in-house fuel systems, agricultural USTs.
Solvents, acids and industrial liquids stored underground.
For old USTs being taken out of service — complete remediation and proper closure.
From the first call to the final documentation — a transparent, documented and compliant process.
Site survey, safety assessment.
Two teams — one in the tank, one at the surface.
Continuously, before and during the work.
Dedicated equipment for confined spaces.
