What is the expected benefit of using a cathodically protected tank?

Using a cathodically protected tank provides significant protection against corrosion, which is a primary concern for underground storage tanks (USTs). Corrosion can lead to leaks and environmental contamination, posing risks not only to the surrounding environment but also to human health. By implementing cathodic protection, an electrochemical method, the tank’s metal surfaces are effectively shielded from corrosive elements, particularly when buried underground, where moisture and soil conditions can accelerate deterioration.

This process involves using sacrificial anodes or impressed current systems that either corrode instead of the tank material or actively repel corrosion processes, thereby extending the lifespan of the tank and maintaining its structural integrity. Ensuring that tanks are well-protected against corrosion is crucial for compliance with regulatory requirements and for the safe storage of fuel and other hazardous materials.
