Sutro Reservoir Rehab and Seismic Upgrade (WSIP)

Reinforcing the columns that will support the roof.

 

Project Update

Upgrade of City’s Third-Largest Reservoir Proceeding on Schedule

Seismic upgrade of the Sutro Reservoir continues on schedule, with retrofit of the East Basin (the project’s second half) nearing completion. Currently crews are restoring the roof in addition to reinforcing the walls, putting in new reservoir liner and installing a new electrical system. Refilling and disinfection of the second basin is planned for November, and we expect final completion of the project by early 2015. Reopening of the reservoir grounds (date still to be determined) will follow.

The 60-year-old two-basin reservoir is the third largest in the City. The rehabilitation will enable it to withstand a major earthquake or other disaster, improving the reliability of the entire City’s drinking water supply.

The project is part of our Water System Improvement Program (WSIP), a voter-approved bond-funded program to repair, replace and seismically upgrade the Hetch Hetchy Water System.

Concrete pour on the basin’s south side.
