No federal rule requires a United States data center to disclose its water use
As of this build no federal regulation requires a data center in the United States to report or publish how much water it draws or from what source. Two bills would create such a duty and neither has been enacted, and the EPA is reported to have declined to set nationwide requirements.
The verdict
Absent
The ledger searched and found no instrument. The record says where it looked and when.
Where the ledger looked: Searched the Federal Register full text API for data center water rules and for large load interconnection dockets on 15 September 2026, searched congress.gov and GovInfo for enacted legislation on data center water reporting, and read the introduced texts of S. 4213 and H.R. 9825, which exist precisely because no such duty exists today. No federal rule, standard or reporting form was found. The EPA position reported in June 2026 was that no nationwide environmental requirements would be set.

- The only federal instruments found are bills: S. 4213 introduced 25 March 2026 and H.R. 9825 introduced 22 July 2026.
- Both bills would create the reporting duty, which is evidence that the duty does not exist today.
- The absence is of a disclosure duty. Water withdrawals can still be permitted under state law and under federal permits that apply to any industrial user.
- This record is a written search, not an argument from silence, and it is re-run each month.
What it changes
For an operator, a utility or a community
An operator can answer a community question truthfully by saying that no federal form exists, and then choose whether to publish anyway. A utility asked for a site's draw should check its state's own reporting regime, because that is where any duty lives. A community should stop waiting for a federal filing to appear and should look at state water permits and at the state tracker instead: see /tools/us-ai-energy-policy for the state by state energy record.
