The resource footprint
Modelled averageIn one day, this campus consumes about
6.7950-metre swimming pools
Filled with the volume of water consumed by the campus and its electricity supply.
The actual estimate4,483,782 US gallons consumed
Power-plant water may come from a different watershed. This is a volume comparison, not a claim that households lose this water.
At current operating capacity · Annual model spread evenly over time, not a live meter. Site estimates may differ by roughly ±40%.
Comparison sizes & sources
One pool = 50 × 25 × 2 metres = 2.5 million litres (about 660,430 US gallons). Pool depths vary; this is a defined comparison size.
One home-year = 10,791 kWh, the EIA’s 2022 average US residential electricity purchases. This excludes electricity generated at home and is a fixed US benchmark for all sites.
One car-year = 4.6 tonnes CO₂, the EPA’s typical passenger vehicle tailpipe estimate. The campus model is in CO₂e; the comparison expresses approximate climate scale, not equal mixtures of pollutants.
Monthly values are annual totals ÷ 12; daily values are annual totals ÷ 365. Actual demand varies. Comparisons cover the whole campus, including non-AI uses.
Water: see the numbers and sources
This is water used up, mainly through evaporation. Power-generation water may be used in a different watershed.
- Pressure on local water
- Low-Medium — a regional measure of demand compared with available water
- Where the water comes from
- Municipal potable supply
- Cooling
- Evaporative cooling towers on industrial-park supply
- Basis
- Fitted to a published figure of 1,081 million gallons a year (2025)
- Operator table
- Withdrew 1,397 million gallons, discharged 315, consumed 1,081
- Claimed vs observed
- Google 2026 Environmental Report (FY2025): withdrew 1,396.7 million gallons, discharged 315.3, consumed 1,081.4 — second only to Council Bluffs in Google's US fleet.
Air: see the numbers and sources
The totals include nitrogen oxides, sulphur dioxide and fine particles. They cover both this site and the power plants supplying it.
- Health range
- $36.7–104 million a year. Lower bound is EASIUR national mid-range; upper is EPA benefit-per-ton at a ~$12M VSL.
- Statistical deaths
- 8.69 a year at that VSL — a national-average conversion from tons, not a local concentration study.
- Equals
- 750,743 cars of NOx
- Where it burns
- SPP — Kansas / Oklahoma
- Generation mix
- Wind 45 · Gas 26 · Coal 22
- Diesel backup
- No on-site prime generation reported. Generator permits were not retrieved.
- CO₂e
- 976 kt/yr — climate, not air quality
The project, approvals and community concerns
- Who asked for it
- Google — self-build; Epoch AI models TPU v5p and v5e at this campus
- Who approved it
- MidAmerica Industrial Park / Oklahoma Ordnance Works Authority; Grand River Dam Authority supply plus Google PPAs on adjacent Mayes County solar
- What it serves
- Google Cloud, Search, and TPU training
- IT capacity
- 370 MW current capacity / 700 MW full-build scenario
Google's second-thirstiest campus: 1.08 billion gallons consumed in 2025, on a wind-and-gas SPP grid. Opened in 2011 as Google's second dedicated US hall and has been expanding ever since; a $9 billion Oklahoma package in 2025 covers more Pryor capacity plus Stillwater.
