Pipeline Replacement

PG&E operates the second largest gas transmission and distribution system in the country and has made significant progress in accelerating leak repair and prevention across its 80,000-mile natural gas system.

By the end of 2014, PG&E replaced 2,270 miles of its cast iron and pre-1940 steel distribution main—which can be prone to leaks—with modern, new materials. This means PG&E is one of the first utilities of comparable size and age to complete such an action.
