Thanks in part to the careful planning and preparations, construction of the approximately $41 million pipeline was completed two months ahead of schedule and under budget. In this way, PG&E and its partners helped to ensure that the utility has the necessary infrastructure in place to serve the growing demand within the Sacramento metropolitan area, while minimizing the project’s untoward environmental effects.
