California water infrastructure upgrades

Overview

In late July 2026, the Santa Clara Valley Water District awarded a $1.88 billion contract to a Flatiron-Dragados-Sukut joint venture to rebuild Anderson Dam. The seven-year seismic retrofit, part of a $2.8 billion effort, will reconstruct the dam and spillway, install new outlet pipes, and add safety upgrades, with construction slated to begin in early 2027.

A few days later, on 28 July 2026, the Valley of the Moon Water District opened the Park and Verano Aquifer Storage and Recovery (ASR) project in Sonoma Valley. The ASR system stores water in the aquifer for later recovery during droughts or peak demand, improving local water-supply reliability. The ceremony also reiterated the Anderson Dam contract and highlighted that Valley Water has secured over $114 million in state and federal grants for critical water-infrastructure projects.

By late August 2026, FlatironDragados and Sukut Construction have commenced seismic reinforcement works on the Anderson Dam in Morgan Hill. The project aims to improve the dam's ability to withstand major earthquakes, which would allow the reservoir to return to normal operating levels. Since 2020, the managing agency, Valley Water, has been forced to limit the reservoir to approximately 3% capacity due to seismic safety concerns. The scope of work includes reconstructing the dam body and spillway, installing new drainage infrastructure, and implementing road, utility, and environmental improvements. Additionally, FlatironDragados is nearing completion of a 518-meter-long tunnel designed to serve as a bottom outlet for reservoir level control.

Together, these developments illustrate a coordinated push by California water agencies to strengthen water storage, enhance flood protection, and increase resilience against seismic risk.
