As municipal water system facilities are reaching their life expectancy, the need to rehabilitate or replace water mains is increasing. There is a need for water utilities to maintain their current infrastructure as they struggle to close the gap between current spending and the future capital needs. Corrosion is a phenomenon that concerns most water utilities in North America where about two thirds of the installed water main network consists of various forms of ferrous pipes, including cast iron, ductile iron, and steel pipes. Studies have shown that electrochemical corrosion is the predominant deterioration mechanism on the exterior of cast and ductile iron pipes. Cathodic protection of cast and ductile iron mains is a mitigative measure that has been shown to reduce corrosion of ferrous water mains.
