Our first step is to test the inegrity of your diesel day, surface and inground tanks testing tank structure as well as sludge and water...

tank integrity testing failIntegrity testing or otherwise known tank tightness testing is the most accurate method to ensure the ability of a bulk storage unit to be integral or complete. By pressure differentiation testing for a non-integral system DTTA can ensure that the system is complete by monitoring for allowed pressure drops over time.

Acoustic signature data collection during the pressure differentiation test provides data which can link any pressure drops to specific characteristics, allowing DTTA the ability to determine the likely causes of the pressure deviation.

DTTA’s unique testing systems have been tailored from USPS systems to suit the Australian market, with the ability to assess the integrity of underground and surface bulk storage tanks including surge units and day tanks as well as piping networks for ventilation, fuel feed and return systems and pump circuits.

Tank integrity testing allows DTTA technicians to provide accurate assessment and reporting on the integrity of the bulk storage unit and the surrounding components.

Internal Surface Inspections (ISI)


isi diesel fuel tank integrity inspection‘ISI’ servicing gives you a visual assessment of your bulk storage tanks interior.

Using remote camera technology, the internal surface inspection service allows DTTA technicians to visually inspect and provide accurate assessment of the internal surfaces of the bulk storage unit.

The ISI service allows your DTTA technician access to accurate data and imagery of any imperfections found in the internal surfaces as well as any corrosion or damage to your bulk storage unit.

ISI also provides a visual indication of the bulk stored diesel cleanliness and condition, allowing DTTA to record and provide documentation for any imperfections and monitor or rectify any potential hazards.
