WSIP Year in Review Newsletter
WSIP at 10 Years!
This year our Water System Improvement Program (WSIP) is celebrating its 10th anniversary! As the largest infrastructure project ever undertaken by the San Francisco Public Utilities Commission, and one of the largest in the nation, the WSIP is composed of 83 projects to upgrade, repair and replace our aging water infrastructure. Currently at 80 percent complete, the WSIP has employed 11,000 workers since 2007, and the program has repaired or replaced more than 280 miles of pipeline so far. Watch here for a recap of the WSIP over the past 10 years!
SFPUC Awarded 2013 Employer Champion Award
The SFPUC received the 2013 Employer Champion Award at JobTrain's 29th Annual Breakfast of Champions event on the morning of Friday, May 3, 2013 for their efforts in the hiring of 96 graduates from JobTrain's Project Build (construction) and Laborer's Apprenticeship classes over the last few years. Emilio Cruz accepts the award on behalf of the SFPUC.
Calaveras Dam Replacement Project
As the New Year began, the Calaveras Dam Replacement Project celebrated an achievement of another milestone. The team has successfully moved a total of 2 million cubic yards of rock and soils since the project began in August 2011.
Building a dam is similar to painting a house, in that the majority of the work goes into the preparation. The team needs to remove all the loose materials on both sides of the valley and the valley floor so the new dam will be built upon a solid base. The Calaveras Dam Replacement Project will have to move more than 9 million cubic yards of soils and rock during construction. About 3.5 million cubic yards of the materials will be used in the construction of the new dam, while the remainder will be disposed of onsite.
Seismic reliability. Delivery reliability. Water supply reliability.
The $4.6 billion Water System Improvement Program (WSIP) reached the peak of construction in 2012 with 18 projects valued at $2.6B in construction and all major projects launched. Currently, more than two-thirds of the 81 WSIP projects have completed construction between California’s Central Valley and San Francisco along the landmark Hetch Hetchy Regional Water System delivering water to more than 2.6 million people in the Bay Area.
This past year, redundant seismically-engineered conduits were installed where the Hetch Hetchy Regional Water System crosses three of the nation’s most active earthquake faults to help create a lifeline around the San Francisco Bay.
The program is funded by a bond measure that was approved by San Francisco voters in November 2002 and will be paid for by both retail customers in San Francisco and 26 wholesale customers that serve Alameda, San Mateo and Santa Clara counties.
The WSIP is one of the largest water infrastructure programs in the nation and the largest infrastructure program ever undertaken by the City of San Francisco.
Reliability. Sustainability. Quality. The WSIP objectives include:
- Improve the system to provide high-quality water that reliably meets all current and foreseeable local, State, and Federal requirements.
- Reduce vulnerability of the water system to damage from earthquakes.
- Increase system reliability to deliver water by providing the redundancy needed to accommodate outages.
- Provide improvements related to water supply/drought protection.
- Enhance sustainability through improvements that optimize protection of the natural and human environment.
