May 31st is National Dam Safety Awareness Day

Each year, the nation commemorates May 31st as National Dam Safety Awareness Day. We have an important dam under construction here in Sunol Valley – the Calaveras Dam. Dams play a critical role in our water supply. 

Why is it important?
  • Calaveras Reservoir, impounded by Calaveras Dam, when full provides half of Hetch Hetchy Regional Water System's Bay Area storage
    • Upon completion, we will have a new seismically upgraded dam with a structural height of 220 feet, a crest length of 1210 feet and width of 80 feet at the crest and 1180 feet at the base
    • It is crucial to the reliability of the water supply of 2.6 million people during emergencies and in times of drought
    Today reminds us just how critical our work is here in Sunol Valley to rebuild the Calaveras Dam.

    The following organizations have joined forces to commemorate National Dam Safety Awareness Day on May 31 - the Deep Foundations Institute (DFI), Association of State Dam Safety Officials, National Hydropower Association, U.S. Society on Dams and American Society of Civil Engineers.

    Schedule Update for Calaveras Road Closure

    WSIP Update on Repairing and Upgrading Your Water Infrastructure!



    It’s Infrastructure Week and here at the San Francisco Public Utilities Commission (SFPUC) we have been implementing the Water System Improvement Program (WSIP), a $4.8 billion multi-year capital improvement program, to repair and upgrade our regional and local water system infrastructure to ensure the SFPUC can continue to supply reliable water to 2.6 million people in four Bay Area counties, especially after a major earthquake. 

    Check out what the WSIP has been up to over the last year. 

    Remember #infrastructurematters!

    We are Stronger and Safer Together – National Safety Week


    This week is National Safety Week. Which means construction contractors across the country emphasize one of the most important factors of the job -- SAFETY. Right here in Sunol Valley, we have over 150 workers working on projects such as building the replacement Calaveras Dam.

    At the Calaveras Dam Replacement Project, crews have worked over 140,000 safe working hours since the beginning of the year, without any recordable safety incidents.  A recordable safety incident is when a worker requires medical treatment beyond first aid and there is a loss time on the job. Our last recordable incident was in October 2014. This is well below the industry average.

    Why is this record special? Because our construction crews at the Calaveras Dam Replacement Project work multiple shifts – both day and night – working with huge machinery, excavating earth and rock, on a very complicated job site in challenging conditions. As we continue work to complete the project, we applaud the joint venture of Dragados USA, Flatiron Construction, and Sukut Construction for making safety a priority here at Calaveras Dam during National Safety Week.

    Check out our time lapse capturing excavation work since the beginning of the project:
