Community members and even an enthusiastic furry friend joined the Water System Improvement Program (WSIP) team to learn about water conservation, local wildlife and the Sunol Valley Watershed at the Sunol Wildflower Festival earlier this month. Visitors to our booth tested their knowledge of WSIP facts by spinning the prize wheel to with fun prizes. In case you missed the Festival, here are a couple of the most challenging questions:
· How many gallons of water does the washing machine use? 55 gallons
· Why would we have injected more than 8 million pounds of cement grout into the New Irvington Tunnel during construction? To seal the tunnel heading off from groundwater intrusion
A special thank you to our partners at the East Bay Regional Park District and Alameda Creek Alliance for hosting this wonderful event.

It is fitting that the SFPUC helped host the annual meeting of the United States Society on Dams (USSD) this last week in the same month as the anniversary of the 1906 Great Earthquake and Fire. The group finished their week of technical sessions and presentations on dam safety in extreme events with a field tour of a dam in construction.
That would be our very own Calaveras Dam Replacement Project. The project will construct a new seismically designed earth and rock fill dam right next to the existing, which will be able to withstand the maximum credible earthquake on the Calaveras fault.
The USSD Conference attendees peppered the Calaveras Dam Replacement Project Team with questions. We appreciate that the SFPUC project team members, the Construction Management team from Black & Veatch, Design team from URS, and the contractor Dragados USA/Flatiron/Sukut Construction shared their experiences with their industry colleagues.
Then the Calaveras Team returned to the current work at hand, which is continuing the major excavation work on the new spillway and stilling basin, as well as mechanical and electrical improvements to the new intake Tower.
When complete in late 2018, the replacement dam will enable us to bring the Calaveras Reservoir back to historic capacity, storing approximately half of the Hetch Hetchy Regional Water System’s local Bay area water supply.
This somber anniversary for the 1906 Great Earthquake reminds us to ensure our families are prepared for the next big earthquake. Visit 72hours.org, or http://www.redcross.org/ca/san-francisco/ to learn more.

The Water System Improvement Program (WSIP) prize wheel is back and you only have a few more days to sharpen your knowledge before you spin the wheel at the 2014 Sunol Wildflower Festival. This year’s questions range from fun facts about your local slimy, slithery friends to where your water comes from and if you know the answer, there are fun prizes to win!
We look forward to seeing you at the eleventh annual spring Sunol Wildflower Festival this Saturday, April 12, 2014 from 11 a.m. to 4 p.m. at the Sunol Regional Wilderness. In addition to stopping by our booth, make sure to check out the scheduled nature hikes, crafts, live music and nature activities.
