Water reuse systems for data center cooling

Veolia and Amazon launch a water reuse initiative in Mississippi, deploying autonomous containerized treatment systems to support 2030 water positive targets.

The collaboration introduces a technical framework to transform municipal effluent into industrial-grade cooling water for high-density data centers. By implementing modular, scalable treatment units, the project aims to reduce the withdrawal of local groundwater and potable supplies, contributing to regional water resilience. This initiative is a critical component of Amazon's broader strategy to achieve a "water positive" status across its global data center operations by 2030.

Decentralized Water Treatment and Modular Infrastructure
The project utilizes Veolia’s newly launched Data Center Resource 360 offering, which focuses on the "circularity" of water and energy within the digital supply chain. The first facility, scheduled for completion in 2027, will be the first of its kind in Mississippi to utilize reclaimed water for thermal management.

The technical core of the system consists of autonomous, containerized treatment modules. Once fully operational, the Mississippi project is expected to reuse over 83 million gallons of potable water annually, a volume equivalent to the average annual water consumption of approximately 760 U.S. households.

AI-Enhanced Operations and Predictive Maintenance
Parallel to the physical hardware deployment, Amazon Web Services (AWS) and Veolia are co-developing AI-enhanced operational solutions. These software-defined capabilities are hosted on Amazon's cloud infrastructure, leveraging machine learning and generative AI to optimize the automotive data ecosystem of water management.

Strategic Impact on Water Stewardship
The initiative aligns with Veolia’s Green Up strategic program, which emphasizes resource preservation and decarbonization. By converting "wastewater into cooling power," the partners are addressing the increasing water demands of next-generation AI workloads.

This project serves as a repeatable technical model for industrial water stewardship. As data centers become more power-intensive, the ability to decouple cooling requirements from local drinking water supplies becomes essential for securing a "license to operate" in water-stressed regions. The integration of 5G-enabled sensors and cloud-based AI ensures that these decentralized systems operate with the same reliability as centralized municipal infrastructure.
