Data centers and water
Data Center Water Use in Laramie County, WY
Laramie County, Wyoming has 22 mapped data center facilities, including Microsoft, Meta, carrying about 4.35 GW of estimated power load.
Water pressure for new demandHow hard a large new water user, like a data center, would press on this county's water. It blends recent drinking-water compliance, drought, and existing industrial demand. Higher pressure means new demand competes harder with current uses. It is not a judgment about whether one should be built.
Moderate water pressure
Laramie County has no health violations in the last 5 years, extreme drought, low existing industrial water demand.

Supply versus demand
How much water do Laramie County data centers use?
Exact facility water draw is rarely public. As a screening proxy we compare the Clean Water Act permitted discharge mapped to these facilities against the county's entire industrial water baseline from the USGS 2020 series.
No Clean Water Act permitted discharge is reported for the mapped facilities in Laramie County. The figures below show the county's industrial water baseline for context.
- Mapped facility discharge
- Not reported
- County industrial baseline
- 1.24 Mgal/day
Model a build
Can Laramie County support more data centers?
Laramie County carries 29 on the water-pressure scale, so new large-load demand warrants closer scrutiny. Size a hypothetical build to see the daily draw against the county industrial baseline.

Facility data combines EPA ECHO, EPA Clean Water Act permits, OpenStreetMap, and the IM3 Open Source Data Center Atlas (DOE/PNNL), geocoded to county FIPS. Capacity and water baselines come from IM3 and USGS 2020 water-use data. These are county-level screening figures, not a facility-level water-use audit. Read the full methodology.
