unresolvedsite 'No burden on our water supply'; yet 10 acre-feet 'for industrial use' and up to 1,000 more water shares sought

- Valar at the state economic board (minutes) (2026-07-09): Announced "a waterless data center in Orangeville".GOED Board Meeting Minutes, July 9, 2026 (posted with the Sept 10, 2026 meeting) (Board of the Governor's Office of Economic Development (Utah Public Notice Website), 2026-09-10)
- Carbon County commissioners, as ETV News reported it (2026-07-01): Combining Valar's helium-cooled reactor with NVIDIA's air-cooled chips "eliminates the need to draw from local water supplies".
What the record shows
- Holds for the reactor itself: Ward 250 is cooled by helium, and DOE's review puts site water use at 'less than 1000 gallons/day for domestic use' with no process-water discharge.NEPA Determination DOE-ID-26-005: Valar Ward250 Research Reactor (categorical exclusion B5.26) (U.S. Department of Energy, Office of Nuclear Energy, 2026-04-22)
- Castle Dale City Council minutes, 12 March 2026: Valar's Utah operations director said 'The reactor requires minimal water—about 10 acre-feet for industrial use'. The minutes give no time period; if yearly, that is about 8,900 gallons a day on average, and DOE's review mentions no industrial water.Castle Dale City Council Meeting Minutes, March 12, 2026 (scanned) (Castle Dale City (Utah Public Notice Website), 2026-03-12)
- Orangeville minutes (9 July 2026): 1,000 water shares under discussion are 'not part of the data center'; ETV (28 July) reports Valar plans to obtain up to 1,000 shares for future development on land it is buying.July 9, 2026 City Council Meeting Minutes (Orangeville) (Orangeville City (Utah Public Notice Website), 2026-07-09)
- At the Carbon County site, water is 'considered to be fully appropriated'; Valar would have to buy existing rights and move them by a publicly advertised change application (Trust Lands memo).09.17.2026 TLA Board Packet (Item 10A: SULA 2095-OBA Board of Trustees Memorandum, Carbon County letter, lease map) (Utah Trust Lands Administration (Utah Public Notice Website), 2026-09-17)
The gap: The reactor needs no cooling water, so that part of the claim holds, and Valar's 'waterless' wording refers to cooling. The site and campus plans do use water: Valar told Castle Dale about 10 acre-feet 'for industrial use', with no time period (it could be an allocation rather than a yearly draw), which DOE's review does not mention; Valar is working toward up to 1,000 more water shares for future development; and a Carbon campus would have to buy rights in a fully appropriated basin.
In plain termsWard 250 is cooled by helium gas, not water, and DOE's review lists only household-scale water use; so 'the reactor needs almost no water' holds. But Valar told one city council the reactor needs about 10 acre-feet 'for industrial use,' which, if that is a yearly figure, is roughly nine times DOE's number and appears nowhere in DOE's review. Valar is also working toward up to 1,000 more water shares for future projects, and its Carbon County campus would have to buy water in a basin where the state says all water is already spoken for. 'No burden on our water supply' is true of the reactor's cooling, not of everything Valar plans to build around it.
Why it matters: Water is scarce in Castle Country; figures in the federal review and in local statements should match, and campus-scale use is where the burden would fall.
What would settle it: FOIA to DOE Idaho Operations Office for the environmental checklist Valar submitted for the categorical exclusion; GRAMA to Orangeville City and Castle Valley SSD for Valar's water connection records; watch the State Engineer's 'Notice to Water Users' for any Valar application.
