A review by The Tech Buzz finds that major technology companies including Google, Microsoft, and Meta are consuming billions of gallons of water annually to cool AI data centers, with projections showing demand accelerating as GPU-dense facilities come online. The analysis draws on publicly disclosed water usage effectiveness figures and third-party environmental assessments. Some facilities in water-stressed regions are drawing from the same aquifers serving agricultural and residential users. Researchers and regulators are pressing companies for watershed-specific disclosure rather than aggregate global figures.
