California is implementing various infrastructure and legislative measures to enhance water security and drought resilience. Major projects include the Sites Reservoir, which is entering an investment period following a revised water right permit, and the completion of a $14.3 million upgrade to the Santa Ynez Drinking Water Reservoir in Los Angeles to meet federal safety requirements.

Further efforts include a $78 million water main improvement project in Los Angeles and the completion of a $235 million valve system rehabilitation at Oroville Dam. On the legislative front, a bipartisan Senate committee bill has passed to secure funding for desalination projects to address water stress in the western United States.
