Project Information

The Seismic Upgrade of Bay Division Pipelines Nos. 3 and 4 (BDPL 3&4 Seismic) is part of the San Francisco Public Utilities Commission’s Water System Improvement Program. This project will seismically upgrade two drinking water pipelines where they cross the Hayward Fault in Fremont. To protect the water system, the BDPL 3&4 Seismic project is replacing large sections of the pipelines with high-tech pipe elements and structures designed to protect them from damage during a major earthquake.

The pipelines, known as Bay Division Pipeline Nos. 3 and 4, cross the Hayward Fault near the intersection of Mission Boulevard and I-680 in Fremont. All project work will take place within the SFPUC’s right of way and nearby staging areas.

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 2.6 million customers in the Bay Area, including Alameda County.

Our project team is working closely with local officials to ensure construction schedules are timely and traffic and community inconveniences are minimized.
