Closed-loop liquid cooling means the Meta Lebanon campus will use no water.
What the evidence supports
Meta says the design will recirculate cooling water and use zero water for a majority of the year. That is narrower than zero annual or total campus water use and remains a future design claim until operating measurements exist.
Still unknown
Actual annual withdrawal and consumption, potable and nonpotable shares, the heat-rejection architecture used in operation, and operating measurements.

Why The second review found that a literal zero-water conclusion is not established by Meta's narrower future design statement.
