  • Ventilation systems, including screens designed to prevent birds, insects and debris from entering the tank
  • Inspect the exterior coating of the tank for possible damage
  • Ladders, locks, platforms, ladder cages and safety climbing devices (if specified) for corrosion and/or damage
  • Exterior sealer condition
  • Grounding of cathodic protection system

Interior Tank Inspection

Performed per manufacturer’s recommended intervals. Focuses on the interior portions of the tank, is performed while the tank is out of service, and includes the following inspections:

  • Internal sheet and roof coating integrity, particularly in areas where external damage may have occurred
  • Condition of the sealant used in all joints, at the tank wall-to-floor junction, in the area of sumps, and other tank or floor penetrations
  • Coating on galvanized parts
  • Other interior tank components, riser pipes, level gauges, overflow weirs, etc.
