What is the primary purpose of a cathodic protection system?

The primary purpose of a cathodic protection system is to prevent corrosion. This system is particularly important for underground storage tanks, which are often made of metal and are susceptible to corrosion when buried in soil. Corrosion can lead to leaks, contamination of the surrounding environment, and structural failure of the tank.

A cathodic protection system works by applying an electrical current to the metal structure, which alters the electrochemical environment around it. This current helps to counteract the natural corrosion process. By using sacrificial anodes or impressed current systems, cathodic protection effectively prevents or significantly reduces corrosion, thereby ensuring the long-term integrity of the tank and promoting safe operations.

Understanding the need for corrosion prevention in UST systems is critical for maintaining environmental safety and regulatory compliance.
