The San Vicente Dam Raise project adds 152,000 acre-feet of water storage capacity to the reservoir, enough to serve more than 300,000 homes for a year. Filling the reservoir will take two to five years, depending on water supply and demand conditions statewide. The newly added storage volume is greater than any reservoir in the county. The San Vicente Dam Raise project is the largest piece and final major element of the Water Authori- ty’s $1.5 billion Emergency Storage project, a system of reservoirs, interconnected pipelines, and pumping stations designed to ensure a six-month supply of wa- ter for the San Diego region in case imported water deliveries are interrupted – for instance, by an earth- quake. About one-third of the reservoir’s new capaci- ty – 52,000 acre-feet – is for emergency use. The proj- ect also provides 100,000 acre-feet of “carryover” storage that is designed to be filled during wet years and tapped in dry years. The dam raise project cost $416 million. Related projects that include a surge tank, a pump station and 11 miles of large-diameter underground pipeline brought the overall cost to $838 million. Approximately 200 state and local water leaders, elected officials, civic and business leaders, and community stakeholders attended a dam raise dedi- cation celebration at the project site on Wednesday. “This vital enhancement to the region’s water stor- age system will protect our economy and quality of life during future droughts and water supply emergen- cies,” said Thomas V. Wornham, Chair of the Water Authority’s Board of Directors. “It proves once again that our region’s water agencies, civic leaders and ratepayers are committed to doing what it takes to maintain a reliable supply of water, not only for today but for generations to come.” San Vicente Continues on Page 8 Article courtesy of San Diego County Water Authority 6 CONTRACTOR NEWS HISTORIC SAN VICENTE DAM RAISE PROJECT COMPLETED Largest water storage increase in county history adds 152,000 acre-feet of capacity CONTRACTOR NEWS 7 Originally constructed in 1943 at a height of 220 Ft, the new raise added 117 ft in height. 600,000 CuYds of Roller-compacted Concrete San Vicente Continued from Page 6 and CEO Jerry Sanders praised the Water Authority’s ef- San Vicente Dam has been owned and operated by the forts to diversify its water supplies so that the region is city of San Diego since it was built in 1943 to hold 90,000 no longer dependent on a single supplier for almost all of acre-feet of water for city customers.
