Construction Update
Railroad Crossings:
On Monday, October 6, 2014 crews will start the jack and bore work to cross under the Alameda County Rail Road at the intersection of Main Street, Kilkare Road, and West Foothill Road. If work proceeds as planned, the contractor will begin the jack and bore work underneath the Union Pacific Railroad on Main Street the week of October 20, 2014. This means construction at both railroad crossings will occur at the same time.
What to Expect:
* Crews will insert a steel casing from the driving pit at the intersection of West Foothill and Kilkare Road to a receiving pit (next to the Depot Parking lot).
* Kilkare Road will be reduced to one-lane traffic during daytime at the railroad crossing. We appreciate your patience with the expected traffic delays in the area.
* Access through the area will be allowed at all times, but please prepare for delays.
* Crews might need to hand drill under the railroads to remove rocks. The equipment will generate some noise.
Bridge Crossings:
Next week, crews will complete all work related to the bridge crossings at Sinbad Creek on Bond Street as well as on Foothill Road.
Hydrant Installation:
The majority of the hydrants will have been installed at their marked locations by the end of October. There is one hydrant on Main Street that will not be installed until after the jack and bore work is completed. The hydrants should be available for use in November.
As always, please do not hesitate to contact us with any questions, comments, or concerns. The 24-hour Answering Line: (866) 973-1476 or epowell@sfwater.org or blauppe@sfwater.org.

Town of Sunol Fire Suppression System Project
Construction Update
Railroad Crossings:
Our crews have encountered difficult ground conditions at the railroad crossings that have affected our schedule. We will likely have to use a larger drill rig to break through the rocky ground.
Starting this week, we hope to begin crossing under the Alameda County Rail Road at the intersection of Main Street, Kilkare Road, and West Foothill Road. The driving pit will be at the intersection of West Foothill Road and Kilkare. If all proceeds well, the contractor will begin driving underneath the Union Pacific Railroad on Main Street in early to mid-October.
What to Expect:
* Crews will dig a deep pit on both sides of the railroad, and they will insert pipe from the driving pit at the intersection of West Foothill and Kilkare Road. The receiving pit will be near the Depot Parking lot.
* Kilkare Road will be reduced to one-lane traffic during daytime at the railroad crossing. We appreciate your patience with the expected traffic delays in the area.
* Access through the area will be allowed at all times, but please prepare for delays.
* Crews might have to hand drill under the railroads to remove rocks - the equipment will generate some noise.
Bridge Crossings:
Crews will lay pipe across the bridges at Sinbad Creek on Bond Street towards the week of September 29th, and on Foothill Road the week of October 6, 2014. Crews will bore through the abutments and hang pipe on the bridges.
Hydrant Installation:
The majority of the hydrants will have been installed at their marked locations by the end of September. There are a few hydrants on Main Street that will not be installed until after the jack and bore work is completed. The hydrants should be available in November.
As always, please do not hesitate to contact us with any questions, comments, or concerns. The 24-hour Answering Line: (866) 973-1476 or epowell@sfwater.org or blauppe@sfwater.org.

Construction Advisory: New Irvington Tunnel Irvington Portal
We wanted to inform you of some very
important construction activity affecting the neighborhood at the Irvington
Portal site off Mission Boulevard.
Irvington Portal work August 27 – September 15:
As part of the process of preparing the tunnel to be brought into service, we will need to provide additional tunnel ventilation to our construction crews at the Irvington Portal site. The equipment will begin mobilizing in the area on August 27, 2014, and work should be complete by September 15, 2014. The ventilation equipment, which includes a fan and generator, will operate 24 hours a day. Cooling air is needed for crews who are lining the tunnel with a cement mortar to prepare it for being put into service. The sound barrier walls will keep the noise to a minimum and the contractor will install additional noise reduction measures.

Disinfection Process starting October 2014:
Starting the first week of October, we will begin the disinfection process to bring the New Irvington Tunnel into service. In order to disinfect the tunnel, crews will need to stage generators and lights for the 24 hour a day filling/disinfection. The set up will occur during day light hours. The filling/disinfection process will take 2-4 days to complete once it begins. The expected night time activities should be limited to three nights.

What Happens Next?
The New Irvington Tunnel is anticipated to be in service delivering water sometime in November. The above ground work and restoration will continue into early 2015. These include final installations and burial of the new portal facilities, construction of a new security bunker at the existing tunnel portal (on top of the hill), and site restoration work, planting and fencing. The remaining sound walls will be removed after the entire site is restored.

Project Background
The New Irvington Tunnel Project is part of the $4.6 billion Water System Improvement Program (WSIP) to repair, replace, and upgrade our system’s aging pipelines, tunnels, and dams. The new 3.5 mile long tunnel will provide a seismically-designed connection between water supplies from the Sierra Nevada Mountains and the Alameda Watershed to Bay Area water distribution systems. Final construction is expected to be complete in 2015.

Why we should all be excited about Cement Mortar Lining
The
really big news from the team constructing the New Irvington Tunnel – a seismically
designed crucial tunnel between Sunol Valley and Fremont and our 2.6 million
Bay Area customers – is that installation of the cement mortar lining has
begun! Although this may seem like a
good time to yawn, this is actually really exciting news! Here’s why.
It
is one of the final stages of constructing a water tunnel before we bring it
into service. The New Irvington Tunnel
is 95% complete, and we hope to bring the new tunnel into service this
fall. Now are you more excited?
First
we excavated the tunnel from four different locations using road headers and
drill and blast methods. Then we inserted steel pipe final liners into the 3.5
mile long tunnel. We welded the pipe together and injected grout in the space
between the pipe and the tunnel to seal it off from groundwater intrusion along
the entire 3.5 mile length.
There
is still work left to be done before water delivery can begin, but cement
mortar lining application is a key step to prevent corrosion of the steel pipe
and prepare it for water conveyance. Our
workers will use specialized equipment that sprays cement on the pipe’s
interior and creates a very smooth surface.
Mortar Lining being applied in the New Irvington Tunnel
Installation of the mortar lining should take about two months. After that we will complete the
pipeline connections on both ends of the tunnel and install rounded dishhead
caps on the end of the pipe. Then SFPUC
Operation crews will disinfect the entire pipe, flush it and bring it into
service by the end of October 2015. Surface
work and restoration will then take up the remaining months of the project. We
anticipate being done in summer 2015.
So
although the words “mortar lining installation” might not stop traffic, it is
music to our ears!
