Recognizing, testing for and correcting stray current corrosion conditions are a fundamental part of a corrosion technician's job.

This paper will describe the interference that occurred between a pipeline with an impressed current cathodic protection system and a pivot irrigation system located in the same right-of-way.

Due to the lack of consistent rainfall in the Midwest some crops require irrigation. A Pivot Irrigation System is located in the center of the field. The irrigation pivot arm can extend 1000' from the center of the field and travels on equally spaced electric motor driven tower supports with rubber tired wheels. The water is applied evenly as the irrigation pivot arm circles the field.

This paper will describe the interference caused by the ICCP to the pivot wheels and the innovative solutions applied to this problem.
