In the United States, there are approximately 700,000 aboveground bulk storage tanks. While aboveground storage tanks are built to withstand the elements, one fact remains: tanks leak if left unchecked. Tank leaks can occur due to several factors, including faulty equipment, corrosion, and UV degradation, to name a few. We take tank leaks very seriously at American Tanks because they can cause environmental contamination as well as workplace injuries. For clients across the country, we offer an all-inclusive approach to tank management, including regular inspections, repair guidelines, and onsite remediation.
Water storage tanks must be inspected and cleaned on a regular basis to help maintain good water quality in the distribution system and to help extend the tank’s life. Regular tank inspections can also help to identify minor issues before they become major issues, which can cause health problems and lead to costly repairs or premature tank failure. Tanks that are not cleaned on a regular basis can cause contamination events that are harmful to human health or contribute to aesthetic complaints.
Why Tank Inspections Matter
A tank leak can cause a variety of serious problems. A leaking tank can cause cosmetic issues, costly repairs, or tank failure. More importantly, a tank leak can cause significant environmental contamination as well as workplace injuries. Finally, regular tank inspections are critical for detecting and resolving potentially catastrophic tank issues. You may believe you can detect a leaking tank on your own, but this is not always the case. Many tank leaks go unnoticed for years, leaking products into the surrounding groundwater before the issue is addressed.
What Does a Tank Inspection Entail?
First, we will determine the type of tank inspection you require based on the contents of your storage tank. During our comprehensive tank inspections, we provide a wide range of services, including:
- Roof inspection, including dome and seals
- Shell inspection
- Tank floor
- Aperture
- Coating and liner
- Evaluation of settlement
- Strapping and calibration
- Nozzle inspection
Our expert tank inspectors will begin by inspecting the exterior of your tank for cracks or crazing. If cracks are discovered, our inspector will determine the depth and severity of the crack before proceeding with further testing. Our inspectors will also look for corrosion that is eroding the walls of your tank. Finally, our inspectors will inspect the tank containment area for environmental hazards. If tank problems are discovered, it is not the end of the world. Our inspectors will assess the damage and make recommendations to help you comply. Our team can often help you resolve any leaks within 24 hours of your inspection.
How often should a water system inspect and clean storage tanks?
The interval between inspections and cleanings can vary depending on the type of tank and the quality of the water. A water storage tank should be inspected at least every five years, or more frequently if required by the state. Cleaning and repairs should be addressed based on the tank inspection findings. Additional inspections are encouraged between maintenance intervals.
Circulation
Circulation is essential for preventing the stratification of water within a tank. As an aside, freezing of potable storage tanks should be avoided with proper circulation and water turnover.
Water is typically added to and drawn from the bottom of the water container via inlet and outlet piping. The water level rises when the fill rate exceeds the draw rate. When the draw rate exceeds the fill rate, the water level falls. If the fill and draw rates remain constant, the system draws the water that was just added. As a result, the water at the top of the container stagnates due to a lack of circulation, resulting in stratified and stagnant water. Furthermore, the chlorine that remains in stagnant water can deplete, allowing microbial growth as well as the development of tastes and odors. Adding mixers to your tank to help with these issues is a common and cost-effective way to prevent this.
