Data centers and water
Data Center Water Use in Los Angeles County, CA
Los Angeles County, California has 19 mapped data center facilities, including AWS, carrying about 120 MW 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.
Low water pressure
Los Angeles County has no health violations in the last 5 years, no drought stress, high existing industrial water demand baseline.

Supply versus demand
How much water do Los Angeles 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 Los Angeles County. The figures below show the county's industrial water baseline for context.

Model a build
Can Los Angeles County support more data centers?
On the water-pressure scale, Los Angeles County sits at 10, below the national median, so new large-load demand has more slack here than in most counties. Size a hypothetical build to see the daily draw against the county industrial baseline.

Los Angeles County is one of 330 US counties with mapped data centers. See the full ranking and the interactive map in the national atlas.
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.
