The CWF project is a comprehensive effort to improve water conveyance from the Delta area to Southern California. A key aspect of the project is to ensure that the new structures are as resilient as possible in this earthquake-prone area, safeguarding water supply throughout Southern California. It will also provide ecological and environmental benefits for the Sacramento and San Joaquin river deltas at the north end of San Francisco Bay.

The project involves constructing conveyance facilities which include three river water intakes, twin 30-mile long, 40ft diameter deep main tunnels, two forebays, a pumping plant and canals to deliver water from the Sacramento River to existing infrastructure, including the State Water project and Central Valley project pumping plants located 42 miles away in the Southern end of the Delta.

Fugro will deliver an integrated site characterisation program and engineering support to optimise design and minimise construction risks. The program comprises geological assessment, geophysics, drilling, sampling and laboratory testing.

Brice Bouffard, director of the land division said: "We are extremely pleased to work with the Delta Conveyance Design and Construction Authority in support of this important project that will contribute to improving the delivery of fresh water to millions of Californians. In line with our ‘Path to Profitable Growth' strategy, we are leveraging our core expertise and assets to increasingly deliver services in support of amongst others fresh water supply. As a result of global trends such as climate change and population growth, this market is expected to grow significantly."

The five-year contract for Fugro and its partners is valued at US$75 million. The Fugro team for this contract includes five sub-consultants as well as over 35 speciality sub-contractors.
