How Dirty Water Is Powering the AI Boom

Veolia and Amazon will reuse 83M gallons of treated wastewater annually to cool Mississippi data centers starting 2027

9 Jun 2026

Amazon and Veolia have agreed to redirect treated wastewater for cooling data centres in Mississippi, targeting reuse of more than 83 million gallons per year. That volume is roughly equivalent to the annual water supply of 760 US homes. Operations are scheduled to begin in 2027.

The deal responds directly to growing scrutiny over freshwater use by data centres, whose cooling demands have risen sharply alongside the expansion of artificial intelligence infrastructure. Amazon has committed to returning more water to communities than its data centre operations consume by 2030.

Veolia's containerised treatment systems will draw effluent from nearby municipal plants and process it to meet industrial cooling standards. The technology is designed for replication, and Veolia is packaging the approach under its Data Center Resource 360 offering, which positions data centres as circular water hubs rather than net consumers.

AI sits inside the operational layer too. Amazon will provide cloud infrastructure and generative AI tools to support real-time process optimisation and predictive maintenance across Veolia's global water treatment network.

"By combining Veolia's water expertise with Amazon's AI technologies, we're transforming data centers into engines of innovation for sustainability," said Veolia chief executive Estelle Brachlianoff.

Replicating the model elsewhere will not be straightforward. Permitting timelines, local effluent quality, and available wastewater volumes will each constrain how widely the approach can scale across different regions.
