How Vertiv's PurgeRite Advances Data Centre Water Recycling

AI workloads are reshaping the data centre landscape, pushing facilities towards higher-density computing and more sophisticated cooling systems.

With that, operators are facing fresh challenges around water sourcing, wastewater management and infrastructure commissioning.

Vertiv is aiming to address those pressures with the launch of Vertiv PurgeRite NearZero, a fluid management service designed to reduce the water, wastewater and hauling requirements associated with commissioning closed-loop hydronic systems.

The offering combines water recycling, treatment and monitoring technologies to help data centre operators prepare cooling infrastructure for operation while reducing resource consumption.

Cooling infrastructure under pressure

The growth of AI and high-density computing is increasing the complexity of the cooling systems that support modern data centres.

Primary and secondary fluid networks are becoming larger and more critical to overall facility performance, creating new demands during commissioning.

According to Vertiv, operators are encountering challenges linked to water availability, discharge restrictions and maintaining predictable commissioning schedules.

These issues can become more pronounced as facilities scale to support more powerful computing environments.

With NearZero, Vertiv is expanding its cooling capabilities by integrating engineered flush planning, reverse osmosis, continuous water-quality monitoring and closed-loop water recycling into a single service.

Ron Bednar, Senior Vice President of Services, Americas at Vertiv, says the role of fluid infrastructure is becoming more important as data centre designs evolve.

He says: "As data centers move to higher-density architectures, fluid networks are becoming more critical to deployment speed, system cleanliness and long-term reliability.

"Vertiv PurgeRite NearZero helps customers limit water consumption, wastewater handling and hauling complexity during commissioning while supporting the reliability required to bring mission-critical cooling systems online with confidence."

Recycling water throughout commissioning

A key feature of PurgeRite NearZero is its ability to recycle flushing water throughout the commissioning process.

Traditional commissioning approaches can require substantial volumes of fresh water, alongside transportation and disposal activities once the flushing process is complete.

Instead, Vertiv combines mechanical flushing, water treatment and filtration with reverse osmosis and continuous monitoring.

The objective is to reuse water within the commissioning cycle, reducing the amount that must be sourced, transported or discharged.

The company says this supports cleanliness and passivation requirements for closed-loop hydronic systems while helping to minimise water consumption and wastewater generation.

For data centre operators, the benefits extend beyond water conservation.

Reducing hauling requirements can also simplify logistics during large-scale construction and deployment projects, particularly where water delivery and wastewater disposal are subject to local regulations or infrastructure constraints.

As AI data centres continue to expand in size and complexity, the ability to reduce dependencies on external water supply and disposal processes may help improve commissioning efficiency.

Measurable reductions in water use

Vertiv reports that selected deployments of PurgeRite NearZero demonstrate notable reductions in water consumption and related operational requirements compared with conventional commissioning methods.

According to the company, total water consumption is reduced by up to 78%, while water haul-off volumes fall by as much as 91%. Discharge management costs are also reduced by up to 34% in some deployments.

The impact can also be seen in transportation requirements.

At one site, the process reduces water delivery and removal needs by approximately 300 tanker trips.

Fewer journeys mean less truck traffic and lower fuel consumption associated with transporting water to and from a facility.

Vertiv notes that actual results vary depending on project conditions, including incoming water quality, contaminant levels within the system, discharge regulations, local disposal requirements and transportation logistics.

The service complements Vertiv's wider portfolio of thermal management and fluid management offerings for hyperscale, colocation and enterprise data centre environments.
