Annie Li gives us an exclusive, inside look at an engineer’s life at the SFPUC! As a senior civil engineer, Annie worked on the Alameda Siphon No. 4 Project in the Sunol Valley. The project entailed seismically-upgrading the pipeline, which extends approximately 3,000 feet from the Alameda East Portal across both the Calaveras Fault and Alameda Creek to the Alameda West Portal. Check out the video here to learn more about the project, some of SFPUC’s facilities and the road to becoming an engineer.
