This type tank is located above ground and is generally easier to inspect visually.

While you may think that a visible inspection of the tank exterior will clearly display signs of weathering or leaking, this is not always the case. Small leaks or unseen damage may be present in hidden or covered areas.

It is the obligation of a tank owner or operator to maintain a tank to ensure the safety of persons and the surrounding environment.

The integral nature of the tank or the requirement for further maintenance, cleaning or repair work to the tanks can be determined by a comprehensive integrity test and inspection.
