Recycled Wastewater Can Cool AI Data Centers, but Potable Water Use Persists
Recycled wastewater can cool AI data centers, but Loudoun County still draws 260 million gallons of potable water daily as infrastructure buildout lags.
Summary
TechCrunch reported on August 20, 2026, that Liquid Death and Garage Beer enlisted former Philadelphia Eagles star Jason Kelce for a campaign proposing urine to cool AI data centers, which require millions of gallons of water. The joke reflects a real practice: treated wastewater and sewage, including urine, can displace potable water, said Ecolab executive Michael Obradovitch and Bruno Pigott, WateReuse Association executive director and former acting EPA water assistant administrator. Raw urine is unsuitable because salts, urea, bacteria and organic matter cause deposits and constant cleaning, while evaporative cooling would pass hot air through it. Astronauts convert urine into drinking water, but that is inefficient at scale. Treatment plants instead use membrane bioreactors, reverse osmosis and ultraviolet light to produce industrial water, sometimes potable water.
CDM Smith water reuse leader Dr. Greta Zornes, a specialist for more than two decades, said data center demand has driven a recycled-water boom, but projects need nearby plants capable of treating millions of gallons daily. Rural facilities are often too small, and infrastructure takes time. Loudoun County, Virginia, outside Washington, D.C., has more than 250 data centers and at least two dozen planned. In 2025, they used about 200 million recycled gallons daily, 43% of consumption, while 260 million potable gallons supplied 57%, according to Loudoun Water. Obradovitch said data centers could anchor municipal upgrades; Meta will invest at least $270 million near its facilities while losing about $4 billion quarterly on Reality Labs. Pigott supports legislation offering a 30% recycled-water infrastructure tax credit. A Gallup poll found about seven in ten Americans oppose data centers in their communities amid consumer backlash against AI products.
Positives
- About 200 million recycled gallons supplied 43% of Loudoun County data centers’ daily water consumption in 2025.
- Meta will invest at least $270 million in wastewater infrastructure projects near its data centers.
- Membrane bioreactors, reverse osmosis and ultraviolet light can make sewage water suitable for industrial cooling and sometimes drinking.
- A proposed 30% tax credit could accelerate recycled-water infrastructure for data centers and other industries.
- More than two decades of industrial water reuse experience give data center operators established treatment methods to adopt.
Risks & concerns
- About 260 million potable gallons still supplied 57% of Loudoun County data centers’ daily water consumption in 2025.
- More than 250 Loudoun County data centers operate today, with at least two dozen more planned.
- Rural wastewater plants often cannot treat the millions of gallons required daily, while new infrastructure takes time to build.
- Raw urine contains salts, urea, bacteria and organic matter that would create mineral deposits and require constant cooling-system cleaning.
- About seven in ten Americans oppose data centers in their communities, according to a recent Gallup poll.
