16. How Much Water Would the Whole Site Use?
The earlier water article asked where Site Layer 1 would get water. A second question is just as important: how much would the entire site need during its hottest, driest, busiest period? A yearly average may conceal the moment when wells and other users face the greatest pressure.
The applicant’s published notice describes generating engines, but does not provide the complete water balance for computing, generation, construction, and ordinary building uses. I cannot infer this project’s withdrawals from another company’s data center or from the engines’ nominal power rating.
Cooling language can be misleading. Water may recirculate in a closed loop at the chips while a separate cooling tower evaporates replacement water to reject heat. DOE’s explanation traces those loops. Air-cooled or dry systems can reduce direct water use, but may require more electricity under hot conditions; DOE advises evaluating the combined water and energy effect rather than one number alone.
Grant County needs separate figures for withdrawal, consumption, and discharge. It also needs the source wells or suppliers, legal rights, groundwater analysis, and a plan for any users affected if predicted drawdown proves wrong. A design using treated or reclaimed water would still need a named supply, treatment plan, and dependable pipeline. No such choice is confirmed for this project in the reviewed notice.
I would want the same comparison for opening day and full buildout: normal year, extreme heat, prolonged drought, and a failure of the preferred cooling equipment. The power plant’s cooling and treatment water belong in the total. So do fire protection, maintenance refills, and wastewater. An independently reviewed model should account for other pumping in the relevant basin.
What a useful answer would include
A seasonal whole-site water balance, peak-day demand, identified rights and wells, cumulative groundwater study, baseline monitoring, and funded response thresholds. Publish measured results after operation begins.
Questions worth asking
- What are annual and peak-day withdrawals at each phase?
- Which components consume water, and which merely recirculate it?
- What changes during heat or drought?
- Which wells and rights supply the water, and how could nearby users be affected?
- Who pays for monitoring and an immediate remedy if a well is harmed?
