Welcome to our brand new project blog!
In August, preconstruction activities, including environmental surveying, kicked off at the project site of the Seismic Upgrade of Bay Division Pipeline Nos. 3 and 4 (BDPL3&4 Seismic). The goal of this important project is to seismically upgrade and strengthen two existing water pipelines where they cross the Hayward Fault in Fremont.
Currently, the project is in the final phases of design and is expected to go out for bid by the end of the year. The world-class engineers at Jacobs Engineering are working closely with San Francisco Public Utilities Commission (SFPUC) engineers to develop high-tech pipeline improvements that will allow the regional water system to withstand a major earthquake on the Hayward Fault.
The seismic upgrade of Bay Division Pipeline Nos. 3 and 4 will improve the reliability of the water system for the Hetch Hetchy Regional Water System’s 2.5 million customers in the Bay Area, including Alameda County.
Advanced pipe elements like the ball joint pictured above will protect the new pipeline during a major earthquake on the Hayward Fault.
As the project progresses, we hope this blog will serve as a valuable resource for you and your neighbors. Check back frequently for construction updates, work details, traffic notices and fun facts about construction and engineering. For now, please visit our project page for more information about what to expect, and download our most recent construction notice at the bottom of this post to learn about the work currently underway.
If you have any questions or concerns, we encourage you to contact the Public Outreach Team. You can reach us by phone on our 24-Hour Project Hotline at 800-571-6610, or email us at baydivision@sfwater.org.
Thank you for your interest in the SFPUC Water System Improvement Program’s Seismic Upgrade project! We look forward to working with you and we hope you enjoy learning about this important public works project.
