Question reviewed
Answer
Verdict on the wording above: Unknown We looked; the reviewed sources do not establish it. Unknown is not zero, not absent, not noncompliant. How verdicts work →
- How it was framed
- A question DataCenterData examined; no one is quoted.
- What the evidence establishes
- We looked. The reviewed sources do not establish it. 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. Unknown is not zero, not absent and not a failure.
- Biggest limitation
- Actual annual withdrawal and consumption, potable and nonpotable shares, the heat-rejection architecture used in operation, and operating measurements.
- Checked

From Partially supported; unknowns not recorded
To Not independently verified; operating water unknowns and the future design scope are explicit
Why The second review found that a literal zero-water conclusion is not established by Meta's narrower future design statement.
Evidence re-reading of the sources already cited on this claim; no new source.

From Not independently verified
To Unknown
Why The prior label is defined for an unverified statement by a non-company party. This card tests a common inference instead; the reviewed company source does not establish annual or total campus water use.
