Data centers: water use disclosures.

Chamber Passed·5/27/26

California AB2469 mandates water use disclosures and assessments for data centers, requiring local approvals for construction or expansion.

California AB2469 establishes requirements for data centers to disclose water use and implement water scarcity plans. Local governments cannot approve data center construction or expansion without specific assessments and plans. These include a water supply assessment, water use assessment, and a water scarcity plan. The bill also mandates a cooling alternatives analysis and detailed water use estimates. The Department of Water Resources and the State Water Resources Control Board must recommend a water use classification system for large consumptive use facilities by June 30, 2028.
