Fall/Winter 2010 Update: New Crystal Springs Bypass Tunnel

The San Francisco Public Utilities Commission (SFPUC) is making significant progress on the completion of the New Crystal Springs Bypass Tunnel & Pipeline near Polhemus Road in San Mateo. We’re on schedule and making excellent progress. We expect full completion in Fall 2011.

Here is what neighbors can expect in October & November:

Surface pipeline testing work will take place into November.

Roof work will continue on the vaults at the South Shaft site.

In between rain, dust control measures are in place to reduce the amount of dust near our construction site.

The meadow area behind the trailers at the South Shaft site has been regraded. Native grass and plant seeds will be broadcast in the next month.

In January 2011, important pipeline connection activities will require additional work hours at night for approximately 2 weeks. More information and details will be provided in advance.
