Underground tanks (UST – Underground Storage Tank) are among the most complex structures to clean. Restricted access (top entry only), potentially explosive atmospheres, limited room for the crew — all of this makes the job demanding. It takes experienced crews, specialized equipment and strict protocols.
EZO TEH 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 confined-space work. We work with all types of UST.
We are especially experienced with petrol station USTs — typically 20,000-50,000 litres in capacity, with restricted access. We work night shifts or during planned maintenance. Every job follows full safety protocols, including a standby team at the surface.
The complete package — biological products, a team certified to ISO 9001, 14001, 27001, 45001, 50001 and ADR, full documentation.
The most common type — diesel/petrol tanks at petrol stations.
Factories with internal fuel systems, agricultural USTs.
Solvents, acids and industrial liquids in underground storage.
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 and one at the surface.
Continuous, before and during the work.
Specialized equipment.
Wall inspection, report, certificate.
Refineries, petrol stations, oil processing plants, petroleum product depots. ADR certification for work with hazardous classes.
Foundries, rolling mills, metalworking shops. Removal of metal dust, grease, oil and corrosive deposits.
Thermal power plants, hydroelectric plants, boiler houses, transformer substations. Work scheduled during planned maintenance shutdowns.
Production plants, assembly lines, paint shops, service centres and machine shops.
Dairies, bakeries, meat processors, breweries, confectioners. Products safe for contact with food and industrial surfaces.
Facilities producing medicines and medical devices. Compliant with pharmaceutical standards, sterile processes.
