Oracle Corporation has engineered and deployed a direct-to-chip, closed-loop, non-evaporative cooling architecture across its new AI data center facilities. This design eliminates ongoing community water consumption for cooling purposes entirely. Once the system is filled at construction using water delivered by tankers, it operates as a permanently sealed, recirculating system with no evaporation, no blowdown, and no continuous makeup water requirement. This white paper documents the engineering basis of that design, its community impact profile, and its significance as a counter-narrative to opposition claims that modern data centers pose a water resource threat.
