What system is used to manage corrosion in pipelines?

A cathodic protection system is utilized to manage corrosion in pipelines, particularly in metallic pipelines that are susceptible to electrochemical corrosion. This system works by either using sacrificial anodes, which corrode preferentially, or by applying an external current to offset the corrosion process. By doing so, it creates a protective environment for the pipe material, significantly extending the lifespan of pipelines and preventing leaks or failures that could result from corrosion.

Understanding this concept is essential for water operators because corrosion can lead to serious infrastructure issues, impacting water quality and safety. The effectiveness of a cathodic protection system ensures that the pipelines remain intact and functional over time, thus safeguarding both the distribution of water and the reliability of the infrastructure.
