Jacobs was selected by the Delta Conveyance Design and Construction Authority (DCA) for engineering design management services related to the California WaterFix program.

Jacobs' initial $93 million contract will support the preliminary and final engineering design phase of the 15-year program. Major infrastructure components include three water diversion intakes (3,000 cubic feet per second (cfs) each) with fish screens, two large tunnels (40 ft diameter and 35 miles long), two large pumping stations (4,500 cfs each) and new roads and utility relocations.

Following more than a decade of studies, WaterFix was chosen to address California's water shortages while also improving environmental conditions in the Sacramento-San Joaquin Delta.

Estimated at $17 billion in 2017, WaterFix is intended to bolster the reliability of the state's water supplies, while protecting and enhancing the San Francisco Bay-Delta estuary.

The program is slated to begin in early 2019, and will upgrade outdated and unreliable water infrastructure that is more than 50 years old and that depends on levees that potentially put water supply at risk from earthquakes and sea-level rise.

Jacobs provides services that include scientific, technical, professional and construction- and program-management for business, industrial, commercial, government and infrastructure sectors.
