The EPA's facility registry lists Oppidan Data Center at 5341 N. Hanley Road, Berkeley, MO 63134 in Berkeley, Missouri, with a water permit. It is not yet verified: a public permit shows this site exists; its current status has not been confirmed from a record.
How much power it needs, how much water it would use and who would use it have not been disclosed.
How to read this page. Every fact links to the source it rests on; a number in brackets is its place in the source list. A figure no source gives reads Not disclosed, and nothing is estimated. Where sources give different figures, each is shown with who gave it, and another source's figure never stands in for the record's own. Entries are added and never overwritten; corrections are listed under What happened.

The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.
