Water Intrusion Assessment

Over time you may develop a water intrusion problem within your aboveground storage tank (AST) or underground storage tank (UST) system resulting from construction defects, aging, and/or damage to the tank or its appurtenances.  Water intrusion within a tank can interrupt business operations and may result in complaints and loss of customers due to the sale of compromised fuel.  Superior’s fuel quality team specializes in evaluating each tank for points of water intrusion and developing repair strategies that will solve the problem and in turn protect your investment.

Superior understands that water intrusion is a troublesome issue that can lead to any of the following issues:

  • Slow flow, phase separation, and frequent filter changes
  • Accumulation of microbial matter and debris (microbial growth, and fuel decay)
  • Deterioration of inner tank walls and submersibles
  • Damage to dispenser meters requiring replacement
  • Customer dissatisfaction
  • Chronic water alarms and readings
  • Violations if water is not addressed
  • Loss of investment

Superior recognizes these issues are important and will work diligently to determine where the points of water intrusion have occurred.  Common areas of water intrusion within tanks have been found to occur in all the following tank appurtenances:

  • Below grade spill basins and spill basins with direct drains can be stuck open with debris causing water to enter the tank
  • Broken fill or automatic tank gauge (ATG) caps that no longer seal properly can lead to water intrusion
  • Loose tank top risers within high water tables can be a major point of water intrusion
  • Broken or damaged vent cap can be a possible point of water intrusion
  • Highly corroded piping can lead to many different issues, one of which is water intrusion

Once water intrusion problems are accurately diagnosed, Superior will make repair option recommendations enabling clients to make an informed and confident decision based on needs, priorities, and short or long term plans for the tank(s).
