Microsoft data centers in Mount Pleasant in southeast Wisconsin are projected to use much more water annually than would fill four Olympic-size pools.

Water to operate the facilities, including for cooling, will be supplied by the city of Racine.

The first data center, described by Microsoft as “the world’s most powerful data center,” is expected to begin operation in 2026.

Racine projects that facility will use 2.81 million gallons of water (roughly four Olympic pools) in 2026.

But a second data center is also under construction and a 15-center expansion is planned.

Racine projects total water usage will be 8.44 million gallons annually (roughly 12 pools).

The projections don’t include water that will be needed to generate electricity to fuel the data centers.

The Lawrence Berkeley National Laboratory estimated in 2024 that 92.5% of the water U.S. data centers used was to generate electricity, 7.5% for cooling.
