What it really means for a community when a data center comes to town.
The Concern
A data center uses water — mostly to stay cool.
Servers run hot
Racks of computers run around the clock
Cooling needs water
Water carries the heat away
Design sets the draw
Evaporative, hybrid, or closed-loop
Follow the Water
Every gallon withdrawn meets one of three fates.
Withdrawn
Evaporated or leaves with productleaves the watershed — gone
Rechargedsoaks back into the aquifer
Dischargedtreated, returns downstream
By the Numbers
Same ground — what gets withdrawn each year.

Data center figures are illustrative for a ~200 MW facility; actual use depends on cooling design and climate. Cropland: ≈ 300 ac × ~10 in × 27,154 gal/acre-in. Figures rounded.
Withdrawal Isn’t Consumption
What’s withdrawn and what’s consumed differ significantly.

A data center has no product like a crop — its consumed water is all evaporation.
On the same site, a data center can consume significantly less water than the farm use it replaces.
In Summary
Data centers can incorporate special water-cooling processes to decrease withdrawal and evaporation compared to agricultural use.
