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.
What is known
Each figure as its source gave it. The number in brackets is its place in the source list.
- Water
- 238,100,000 gallons a year (withdrawal) measured What at most 2,174 American families use at home, at the EPA's more than 300 gallons a family a day (the EPA gives no year for it).
- [1] sustainability.google
- Who leads it
- Google as stated by the source
- Undisclosed in public filings
- Land, Buildings, Power it would draw, Who would use it, Jobs once it runs, Tax each year
The math behind the comparison
- Google Stonewall Business Park data center, water: 238,100,000 gallons a year.
- 238,100,000 gallons a year ÷ 365 = 652,329 gallons a day.
- Water used at home each day by the average American family, more than: 300 gallons a day.
- 652,328.77 ÷ 300 = 2,174.43 (gallons a day over gallons a day).
Sources:
- Google (opens in a new tab)
- EPA WaterSense, How We Use Water (opens in a new tab), the page's opening paragraph (page last updated August 4, 2026)
The two count different water: the data center figure is water withdrawn from its source, and the EPA's is water used at home, which the EPA does not split into water consumed and water returned.
A comparison is arithmetic on two published rows and is never a new fact (how comparisons are made).

A blank value cell means not disclosed by any source on file; a blank basis cell means the source gave the figure without saying on what basis.
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.
Still not public, and where it would show up
The record adds each the day a source gives it. Why these documents.
- Who would use it A lease announcement or a tenant named in a filing.
- Power the campus would draw A utility or public service commission docket, an interconnection filing, or an air permit for an on site plant.
- Jobs and tax An incentive agreement, a county's economic development filing or a fiscal note.
