UPS Diesel Storage Tank Removal

A photo of the fueling island after the dispenser was removed.

The underground tank has been uncovered so the tank sump and lines can be removed.

The underground tank has been removed and the crew is backfilling the tank grave.

The grave must be compacted every few feet so that no sink holes form after backfilling.

The area has been leveled and is ready for paving.
