This project investigated the technical and economic considerations of retrofitting buried metallic pipelines with cathodic protection (CP). It analyzed the value of existing CP systems and studied related troubleshooting and management techniques currently utilized by water utilities. The project team gathered application data and information from utilities in the United States and Canada through workshops, interviews, and surveys. Case studies demonstrate the economic value of CP, and cover retrofit alternatives for pipes of various lengths and diameters. The project includes a utility-focused design manual, which outlines standard specifications, drawings, and a financial template/methodology to help utilities measure the financial benefit of an anode retrofit program. Published in 2018.
