Data centers and water
Data Center Water Use in Middlesex County, NJ
Middlesex County, New Jersey has 15 mapped data center facilities, including Barclays, DataBank, Digital Realty, carrying about 493 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
Middlesex County has no health violations in the last 5 years, moderate drought, low existing industrial water demand.

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.
