Australia: AWS connects a new data center to recycled water
What's New? Greater Western Water will supply recycled water from its Melton plant to a new AWS data center in western Melbourne, the first Victorian data-center connection designed around recycled cooling water from initial operations.
Why It Matters: The connection converts water stewardship into utility infrastructure, preserving drinking-water capacity while giving the operator a defined alternative supply and the utility a large industrial customer for expanded recycled-water production.
What's Next? The next evidence is completion of connection assets, coordinated commissioning with the new facility, and verified annual potable-water savings as the utility begins the next upgrade phase at the Melton recycled-water plant.

Global: Google adopts watershed tests for cooling choices
What's New? Google introduced water-stewardship principles requiring watershed assessment before new data-center development and limiting water cooling to resilient sources, with air cooling or recycled water selected where local supplies face high risk.
Why It Matters: A corporate commitment becomes a site-selection rule, linking cooling architecture to basin condition before capital is locked. That creates a clearer approval test for communities, utilities, investors, and project development teams.
What's Next? The assessment would strengthen with disclosure of how watershed thresholds are applied, evidence of design changes driven by local risk, and a connection between replenishment claims, site-level consumption, seasonal scarcity, and alternative-cooling performance.

Japan: Daikin and NTT DATA test predictive cooling control
What's New? Daikin and NTT DATA began a July 2026 proof of concept that predicts server thermal conditions from indirect data and coordinates HVAC, chillers, and liquid cooling at an operating Japanese data center.
Why It Matters: Integrated control could reduce systematic overcooling without requiring access to sensitive processor data, giving operators a pathway to lower electricity use while retaining reliability across mixed air and liquid cooling infrastructure.
What's Next? The trial runs through March 2027. Procurement or wider fleet deployment depends on demonstrated prediction accuracy, energy savings, cost reduction, and operational automation under changing workloads and representative summer conditions.

FreeWaterLoop: integrated facility-loop cooling
What It Does: Alfa Laval's FreeWaterLoop combines pumps, heat exchangers, and filtration in one liquid-based facility-loop system, using stable natural-water temperatures for heat transfer while returning water to its source and minimizing net consumption.
Why It Matters: The packaged architecture addresses a deployment gap between high-density computing equipment and external heat rejection, reducing integration complexity while preserving a continuous cooling flow for facilities evaluating alternatives to conventional air-based loops.
Strategic Impact: Commercial value depends on source-water permissions, thermal discharge limits, fouling risk, redundancy, seasonal performance, and verified net-water and energy outcomes across sites, not the novelty of integrated equipment alone in commercial operation.

HyperSolved: end-to-end cooling-water treatment
What It Does: Gradiant says HyperSolved integrates treatment, reuse, chemistry, digital controls, and service delivery for AI data-center cooling water, with deployments already supporting unnamed hyperscale operators across multiple major global operating markets.
Why It Matters: End-to-end accountability can reduce interface risk among treatment packages, cooling assets, water quality, and operating teams. The claimed deployments indicate hyperscalers are buying managed water outcomes rather than assembling isolated equipment components.
Strategic Impact: Because customers and site results remain undisclosed, commercial confidence remains dependent on independently auditable recovery, blowdown, energy, chemical, reliability, and cost data. Verified performance will determine whether integrated service models become a standard hyperscale specification.

Advancing Data Center Cooling Innovation East: 21–23 September 2026
The three-day engineering forum convenes at the Hyatt Regency Dulles in Herndon, Virginia, bringing mechanical, thermal, and cooling specialists from hyperscalers, colocators, developers, engineering firms, equipment suppliers, and contractors.
Focus: Sessions address scalable liquid cooling, heat rejection, water stewardship, facility controls, and utility constraints, with emphasis on operating choices required for higher rack densities and AI-ready infrastructure across established and emerging eastern hubs.
Features: Decision value lies in comparing deployment evidence, commissioning practice, retrofit constraints, water-performance measurement, and the transferability of architectures across climates, utility conditions, workload profiles, and existing facility designs at scale.
