Closing the Water Loop for Data Centers

Data centers rely on consistent, reliable water supplies to manage thermal loads and maintain uptime. Many facilities consume large volumes of freshwater for cooling tower makeup, evaporative cooling, and humidification. As water stress intensifies globally and regulators scrutinize data center water use, facility operators face mounting pressure to demonstrate water stewardship, secure long-term water access, and reduce environmental impact.

Closed-loop water recovery

Aqua Fission enables data centers to close their water loops by recovering clean water from cooling tower blowdown and other onsite process streams. The system separates water from dissolved salts, minerals, and treatment chemicals at low temperature using deep-vacuum distillation. Recovered water is returned to the cooling system or reused elsewhere onsite, reducing demand on municipal supplies and minimizing wastewater discharge.

True zero liquid discharge

Where discharge is prohibited or uneconomical, Aqua Fission can be operated as a zero liquid discharge (ZLD) system. The result is a fully circular water system with no continuous wastewater output. Concentrated residuals are retained as a controlled solid or semi-solid output suitable for compliant disposal or recovery, eliminating the environmental liability of brine discharge.

Onsite water security and autonomy

By recovering and reusing water onsite, data centers reduce exposure to supply interruptions, municipal restrictions, and water price volatility. This improves operational resilience and supports business continuity, especially in regions where water availability is constrained or seasonal.

Cost reduction over time

Reducing reliance on municipal or delivered water can lower operating costs. Aqua Fission eliminates the need for continuous wastewater hauling or disposal, reduces fees associated with discharge permits, and extends the useful life of cooling tower water by reducing blowdown volumes. The low-temperature operation minimizes energy consumption, and modular design enables incremental deployment aligned with facility growth.

ESG leadership and regulatory compliance

Data centers are under increasing scrutiny from investors, customers, and regulators regarding environmental performance. Closing the water loop and achieving ZLD supports environmental, social, and governance (ESG) objectives, strengthens sustainability credentials, and can improve public perception and stakeholder relations. In regions with stringent water conservation mandates, Aqua Fission can help data centers meet or exceed regulatory requirements.

Scalable and modular architecture

Aqua Fission's modular architecture allows systems to scale as data center capacity grows. Units can be deployed in containerized or skid-mounted form, enabling rapid installation and integration with existing infrastructure. The system can be powered by grid electricity, renewables, or waste heat from the data center itself, creating opportunities for energy synergy.

The result

Data centers using Aqua Fission can achieve meaningful reductions in water consumption, eliminate continuous wastewater discharge, improve operational resilience, and demonstrate measurable environmental leadership—all while maintaining the reliability and performance that mission-critical infrastructure demands.
