Cathodic Protection for Transmission Pipelines

Overview

The San Francisco Public Utilities Commission (SFPUC) and its contractor (EXARO) are installing new cathodic protection systems for the corrosion protection of several large diameter water transmission pipelines (Bay Division Pipelines and Palo Alto Pipeline), through SFPUC’s Right of Way at various locations in Fremont, Newark, Redwood City, Mountain View, Los Altos and Stanford. The major components of the cathodic protection installation will include a surface mounted rectifier cabinet, underground deep anode well, excavation to the pipeline and connection to the utility power. The project also includes the installation of test stations along the existing pipe appurtenances for future surveying of the pipeline.
