Concord, CA (March 1, 2023 ) – GEI Consultants has been named the prime consultant for one of the most important water infrastructure projects in California’s San Francisco Bay Area in decades. The Contra Costa Water District’s (CCWD) Phase 2 expansion of the Los Vaqueros Reservoir will provide far-reaching benefits to the people of California. The expansion will include a significant dam raise, new large diameter pipelines and connections, several new pumping plants, and a new marina and recreation facility. GEI will provide Capital Project Management Services to assist CCWD with managing the scope, schedule, and budget for the entire suite of projects. Other services will include risk management, cost estimating, contract administration, providing peer reviews for design, and staff augmentation as requested.

Located in the foothills east of San Francisco, between Livermore and Brentwood, the Los Vaqueros Reservoir is the largest reservoir in the Bay Area. Originally built in 1998 and raised in 2012, the dam can currently store up to 160,000 acre-feet of water. This expansion project will have several potential benefits, including:

  • Increased water supply reliability ranging from 44,000 to 504,000 acre-feet per year in dry periods.
  • Added emergency water supply storage for Bay Area agencies ranging from 80,000 to 120,000 acre-feet per year.
  • Increased environmental water supply ranging from 50,000 to 790,000 acre-feet per year.
  • Improved quality of water delivered to municipal and industrial water treatment facilities.

Construction for the first project is scheduled to begin in 2024 and the entire suite of projects is expected to be complete in 2030.
